- A pile of rust on the ground and an assortment if broken tools tells the story of the day on this bus. The rusted brake caliper and rotor that should have been replaced decades ago are complete trash now.

I had no idea that buses that look so nice on the outside could be a total disaster on the inside with decades of delayed maintenance.
Every bus that looks good usually is a nightmare underneath.
@@BusGreaseMonkey That's why buses, like boats, should be referred to as 'she'.
My thought on this is, don't be so concerned about how much it costs as opposed to can you afford the maintenance?
Yeah seen it time and again. Pretty bus often means Struggle Bus.
haha that makes me laugh, my friend oh my goodness
Scott, you have taught me to stay the hell away from private coaches on the highway. Thank you!
This bus is a very graphic example of what winter road salt can do to any vehicle. Only road salt can be this destructive!
I drove those coaches commercially when they just came off the line. How can they be this old? I know I am not that old!
Thanks for posting this…. better than watching the debate!!
Anything better than watching worthless politics
Those Budd wheels look beyond the end of their life
Very poor shipping on Prevost part
Sad!!!! Disgusting!!!
Poor, poor, poor maintenance. Oops!! NO maintenance
@@jaygraham5407 You do know your posts are in response to mine…right?
As I have gotten older (now 70) I just replace everything (Rotor and calipers on cars) it is just easier, cheaper safer in the long run.
Absolutely insane, why isn't there a way to hold bad/ dangerous mechanics accountable? I just worked on a trailer, it had 3 Haldex and 1 meritor slack adjuster, basically only 3 brakes were working. This bus could've easily gone up in flames. Neither of us has any legal way to hold the previous mechanic accountable.
A long time ago, a n old retired Roadway line mechanic showed me a way to help loosen a bunch of lugnuts like that.
while one guy is hammering on the nut with the impact, another guy hammers straight down on the socket with a heavy hammer. It really helped me with those stubborn ones. Also Keine Tools makes a specialty fixture just made for truck disc brakes(air) that you can just jack them up and roll them away. Have a nice day.
Well, so much for the air vs. cordless strength argument.
Milwaukee has a new version of the 1/2” that is more powerful
IR makes pneumatic 1in that are a lot more powerful (2000 ftlbs) than the old bluepoint he owns and they cost cost about 700 bucks. Cordless is bullshit in a shop, especially when you consider the fact it isn't going to last as long as a pneumatic tool and isn't nearly as durable.
@theprofessorfate6184 that Milwaukee gun is awesome. One wheel in a year it struggled on. And the torque multiplier was going to break and still not get it. It broke the giant bud wheel socket.
A little heat goes a long ways
A little heat doesn’t usually do anything. A lot of heat we go to often but it wasn’t needed
That bus looks like it came from Ohio or new York glad your getting it fixed
I was at first impressed with the Prevost access panels for maintenance until you pointed out the sharp impalers left behind. I would have stuck a piece of packing foam on those because certainly my head would find them.
Couple tips from a 45 year machinist... take the extension off the Milwaukee. The extension absorbs a lot of shock without it.. that Shock will go directly to the socket and break Free More difficult nuts... also rap the top with a heavy hammer when you soak them and every now and then when they don't come Free... the shock helps loosen the thread and migrate the penetrating oil deeper... But it's mostly the shock.. You can get a high frequency to go right through that bolt
..
Extensions loose lots of torque. That is not an extension on the Milwaukee it’s the anvil.
This man and his understudy are capable of anything!
Some of the stuff you guys see in just insane. I hope other maintenance people watch your videos and learn something.
Thanks for the entertainment = struggling with tough jobs. As an Aussie I cannot believe the corrosion that can occur in vehicles in your environment. I have 60 year old cars with no rust.
Keep up the good work
Ken, you have less water and you have no ice so you have no salt so you have no rust.
Scott, put tennis balls with some tape on sharp parts.
Meaning, make a hole in the tennis ball. We use it in film as eye protection from sharp things.
@@51actual Was at a movie setup the other morning and the gaffers had unloaded their truck (space was at a premium) and a cart with color coded "C" stands with a milk crate of yellow tennis balls was in the cart stack. Looking around I saw their use, got to think for everyone on a set...
You can send that Brake Rotor down to Clarke Easterling at Windy Hill Foundry and he'll recycle it for you! 🤣
Great channel reminds me of my dad's shop, only they were working on semi's. The busses are different, but the size of gear and problems are similar.
I`m always amazed of knowledge here on this channel. Scott is a walking breathing book of experience.
I'd fluid film the entire chassis....I'm in the rust belt and I use fluid film on all my vehicles, motorcoach, trailers, tractors, ect... i put that stuff on everything.....i gave up on removing rust up here, just keeping it at bay is cost effective.
I am firm believer in Fluid Film
You fellows do such great work. Look forward to each video.
Another great episode!
I love how you always put safety first when working with your guys 👍👍
The young lad should have had safety glass removing the lug nut, after seeing that socket break…..😮
The labor for the repairs will be more than the coach is worth.
I never used rachets till I had stuff broke loose because they could break. (big farm equipment with big bolts). LOL we used a lot bigger cheater bars as there was more open space on farm equipment. (my uncle was 6-4 230) We also lost a lot of sockets as he dropped the tools where we worked once the job was done. I would like to get a metal detector and sweep the spots we worked. Bet we would find several sets of tools.
Great testament (reason for) impact sockets and breaker bars LOL
I've allways said ,don't paint your studs and nuts😎👍
What a rust bucket 🪣
This Prevost did serve its previous life in the Salt Lake City area...and we all know what that means.
Now you can get an idea of what it was like , repairing busses and coaches for NYC transit
I was taught many years ago, that you do not use a ratchet wrench in high torque situations. Always use flex head bar. I guess things have changed in the last 60 years.
Wow, this has been the most amusing video yet, albeit at your expense. A serious amount of work!
Those removable side are nice for when you have to chain up out west too. Been there done that.The D.O.T. Would have had a field day with that rotor. It really surprises me that bus did not burn down with those calipers as bad as they were! Wow. I cannot tell you how many ratchets,breaker bars, and sockets we broke over the years taking those caliper bolts out. We had the luxury of having an in ground hoist, so we would use a 3/4 breaker bar with a pipe, use a jack stand to support the pipe and let the hoist down. Lol
I guess all this work is cause by the lack of proper maintenance over the years. its amazing that you can really get this stuff apart and have anything left to work with,
That was impressive breaking that many and the type of tools. Lots more work to go though. Someone did this bus massively wrong.
it looks that this bus had a lack of maintenance and it is stuck with rust .May be this bus was decomitionned for quit a long time or that bus run in winter with salt and abrasive and remember this bus has been built in a place called ST-CLAIRE ,QUEBEC with rough winter ,so good luck for the rest of your repairs.
I was in a couple railroad shops years ago and I noticed the tools for the really big bolts were just thick plates steel stampings with the six point hex on one end and the handle end was made for either a hammer or very large extension bar --- no harbor freight ratchets or breaker bars or ratchets of any kind above a certain size - I also saw what had to be some of the biggest dam impact wrenches on the planet, looked like around inch and a half or inch and a quarter drive with sockets that would likely break your foot if you dropped one on it. I assume this kind of thing in the video is why.
Wow I love how much access there is with the panels off. Maintenance should be dumb easy with all that room
I've had to put a 243 lb starter in on the outside of an engine on the ship mostly on my head never any fun. You get it done.
Scott, this is probably one of the worst buses you have had to work on. I can appreciate the issues you have in North America because of road salt but I suggest that the state of this vehicle, the rust everywhere, general neglect, driving it on the roads borders almost on criminal neglect. The condition of this bus has taken years, not weeks! Its is shameful that anyone has let this vehicle get to its current state of general disrepair. I certainly hope that you can get it to a condition that makes it relatively safe to drive on the road, and I hope something can be done about the treatment of the overall rust. The very best of luck to you.
Trust me, he's seen worse.
That 1950’s bus they just did was no picnic either. Old buses seem like a lot of labor. 😂
That Milwaukee looks like a mini anti-aircraft gun.
And Kroil is not overrated.
having a lot of fun with that bus, keep the clips coming
That Icon ratchet was an impressive break I was expecting the yoke to break if any thing did.
Jonathan is a beast! Great assistant
Never again will I look at a shiny coach or RV in the same way. This RV is/was a disaster.
Wow, to break that many tools, so far ... on such a young bus, good luck with the front end 😊
Sounds like my sons 1st car ,, yes one owner vehicle yet every thing I MEAN every thing needs servicing .
Lots of seized things on that Knorr-Bremse brake caliper. Tappets, pins. Probably had water egressed at the booster seal. A real struggle. Don’t miss those days!
Private coaches should be pulled in for random roadside safety inspection.
A young bus wow that’s a new one. I thought he was going to say it was a newer bus.
Good luck trying to get these Lug Nuts off on the side of the road. Oh, well I've had a similar problem getting Lug Nuts off on my 4 wheeler after a Car Dealer visit
Sometimes, I threaded the bolt of nut back on a little to get the bolt nut out of the socket. Hammering the socket or the bolt on the floor or with a hammer sometimes worked it loose.
Never paint threads ! There is much discussion on the next comment, but I have NEVER had a problem. I apply a very thin layer of anti seize to wheel nuts, then I apply the correct torque with a torque wrench. Works like a charm. Mostly because I am the guy who has to remove the wheel next time !
No wheel manufacturers recommend anti seize on threads. None. Lubricated threads are a totally different torque value. Clean and dry with proper torque is perfect. Over torqued wheels from idiot installers is the problem.
Looked brutal; great channel
That brake system is a mess. Good job making it safe. Heavy duty stuff!
I have never seen one rig...let alone one wheel/axle break so many tools. The kicker is that the rig is not horribly old...like Lenny. As for the ratchet failure...I thought the same thing as you did as to teeth/guts failing before the case. It makes me wonder how the tool mfr tests/breaks tools when they are in the design stage.
A great video on a heckuva nightmare scenario...imagine if it had gotten a flat...
You guys never cease to amaze me with the rigs you have brought to you and how many were just a hair away from something catastrophic happening.
The motoring public thanks you in all that you do fixing other peoples eff ups and making things safe again🙂
Lordy-that is gonna be one SPENDY fix. Disc brakes are outstanding-but when they have deteriorated to that extent-get the Amex Black card out.......
All those bolts, nuts and bushings look original. Maybe the shocks could be newer but that’s it. I can’t believe people take care of their equipment so shoddily. At least you can exchange the tools.
How your son and his bus going I havent been getting notifications TH-cam for your channel and you are not the only channel
Nice, dang that’s alot of work. That bus definitely did much of its service in the salt, guessing the passenger side is always worst because of the build up of slush on most roads goes toward that side. Need to try that 1/2” tite reach on those caliper bolts, I use my 3/4” drive Milwaukee impact on mine all the time and have hammered the crap out of it and it’s still going fine. I bought a backup one when you posted that discount but it’s still in the package so far.
I feel certain that bus sat in salt water for an extended time. That’s a ridiculous amount of rust!
I wonder if that bus was one of the ones that got flood damage back several years ago in Nashville
This invoice is going little bit up right.insane grease fitting no grease and brake chambers boots noise on this.thanks video again expose this.😮
Why not use some heat to remove lug nuts
Here in the UK we have a term for those brake discs ....
Well those are well f**ked 👌🏼
This must have been Sponge Bob Square Pants coach🐟🐡🐙🐚🦈
Fancy new calliper brakes and old fashioned neglect. Neglect wins every time.
With that calliper I am not in the least surprised as the required torque for the securing bolts is about 400 lbs ft. On the Volvo B7L they used cap head screws and could be a challenge the break loose… And those callipers are heavy old things as well. Given the amount of corrosion on the thing I suspect that your tool dealer will be rubbing his hands in glee.
Salt=job security.
Part of the problem with the wheel nuts is the paint in the threads.
I was told that if a vehicle you looking at is extremely nice outside. Most of the time there is something being hidden. Putting lipstick on a pig it's still a pig.
It's scary seeing the condition of these buses
Speaking from experience, you may want to have that bus's owner pick up a spare disc brake chamber to carry with, i spent two days trying to find a shop that had one in stock. The chambers for disc brakes are different than the chambers for drum brakes, and don't interchange.........
I’ve never seen a caliber look that bad or a rotor, will take it back. I had metal metal once
holy hell how do you even get lugnuts that tight.
New England road salt.
😅you could save yourselves hours of frustration by using MALTBY Penetrating Oil. Family owned since 1919. I'm an ASE Master tech, been using it for 50 years.
These wheels are as tuff to get off as UPS trailer and dolly wheels.
I believe that the tag axle rim is toast
I didnt know they came with disc brakes being how old it is...and who tightened all the bolts on that axle? Donkey Kong himself??
Looks like the sand blasting box will get some use.
I think the drum brakes with the S cam are a lot simpler and easier to maintain.
This all looks pretty normal up here in Michigan.
those brakes have been hot
Sad, that bus has seen NO Maintenance
Hammer wrenches work well for getting those bolts off
I think hobo Freight will exchange that wrench for you
Air disc brakes have not proven themselves to me yet.
Nastiest brakes I’ve ever seen.
The last wheel you removed appears to have been run with loose luge nuts.
Well I understand why Milwaukee makes that insane gun now, heavy-duty is a different world from light cars\trucks.
Must have lived on the east coast.
All that metal in the rim was stuff the brake pads were throwing off the rotor!!
He was literally using his fingers to pull flakes and chunks off the rim. Yes some of the pile was from the brakes but the rim is bubbling and deteriorating
I allways wire brush end of threads croil them then tap s flat , more croil , it might give a better start
Some gorilla must have torqued up those wheel nuts, lucky it didn't need changing at the side of the road
If you have a quick disconnect coupler on 1 inch gun it could restrict air flow they make hi flow quick disconnect couplers try putting air line directly on gun
I've never seen someone break a rachet
Free socket… Now if only you could find another socket wrench to replace the broken one you would be even.
No wonder people don't travel in states that use salt on roads. I bet there was a lot of shovelling rust and debris off the floor after it left.
It looks like a Le Bus coach, they use alot of salt on the roads in Utah
I have a tire gun I call "Uncle" if it doesn't loosen it it will snap the stud off!
That blue point gun actually sucks, should invest in a IR
gonna be a shocker when you see the cost of the replacement brake components
Cheaper than a bus fire or accident
Got same Milwaukee gun and 12 amp batt ,, many times I go to braker bar and some cheater pipe to give me 2 half meters and I,m 52kg, it works for me unless socket brakes or I slip and go arse up , never happened yet cause I have a idea of 3 points of connection, 2 hands to grab handles or anything for support and then if it won't go with arm strength I go to never fail leg strength 😊 kicks air and Milwaukee arse many times ,, pissing me off that bloody Milwaukee cost us shiploads to buy and many times my cheater bar blitzed it, only good if studs had anti seized on them and not over torque, 2 of worst practices use anti seize and torque wrench, no more issues, bad studs or wheel nuts go in bin
It's a Florida coach alright... Salt everywhere.
Salt Lake City
@@BusGreaseMonkey Wow... ok Didn't realize it was that salty there...
