You do an excellent job explaining things, like an old truck version of essential craftsman! Keep it up man.
Thank you very much!
This has got to be the best most informative video on the internet of tandem hydrovac brake system. Thank you!
I have a 1959 Chevy Viking 40 (2 ton) and equipped with a Bendix HydroVac also, Works very well, My wheels have twin wheel cylinders and this truck even fully loaded stops on a dime with ease.
Great to hear! Sounds like a cool truck too. Out of curiosity, what's your cruising speed on that rig? About 40?
@@SealedBeamRallyTeam When on the freeway I drive 55 mph at 3500 rpms. It has 6.13 - 1 gear ratio.
I recently replaced all the wheel cylinders, master cylinder and booster on my '67 F600. Thank you for explaining the booster in great detail because this information is basically nonexistent. My truck was abandoned for years on an old farm in Georgia that is now a subdivision. Fortunately all the drums were like new. The cab has no rust and the cab mounts have no rust. I wire brushed the floor then sprayed cold galvanized paint before replacing the original rubber factory mat. I put a new fuel tank and all new fuel components, as well. New radiator, water pump and hoses. I replaced the distributor with a new HEI that is a bit more modern than the old points. I love your videos of your truck and I love to see you working with your father. Our old trucks become family members after a while.
Great story! Unfortunately the farm i bought mine from is less than a mile from the incessant march of subdivisions, and particularly ugly ones at that. Guess that's one reason they get put up for sale. Good to save the trucks as family projects even if we can't save the farms.
Very informative video sir! I keep buying big old trucks, and so far all of them seem to have a hydrovac brake system and I was curious how they worked. I'm currently rebuilding the brakes on a 1966 C60. I also found the video about the split rim wheels to be extremely helpful! My truck seems to have the Firestone RH 5s on it.
Thank you for the BONUS chicken cam!!!!! Honey/Buffy is ready for her close up!!!!! Missed Nikki though!!! Loved all the vintage truck brochure shots. I'm ready to get back on our project now!!! (Shhh!!!)
Oh you're gonna work on it again?
@@SealedBeamRallyTeam Yes, indeedee!!
thanks
That was explained well without a bunch of fluff. Well except for the chickens trying to steal the show.
Chickens ALWAYS steal the show!!!
Great vdo i subscribed. Hey looking for 1972 f600 left front brake line. Any suggestions where to find it
Line you'll have to make yourself. Hose you could call Brake & Equipment Warehouse in Minneapolis. They can probably look it up.
@@SealedBeamRallyTeam ty so much for fast reply
Having trouble getting air out brakes. Can a bad booster put air into the system.
Thanks. I just rebuilt my 2 units from a 69 motorhome.
Curious where you got the rebuild kits!
what is the part number of the new booster? where did you get it?
Rebuilt
I have a 64 f600 thats missing all the hydrovac stuff, Im just going to run a fiewall mount booster on it.
You probably have the 300 I6 with the intake on the passenger side right? I wasn't confident I could find a firewall booster that could fit next to the oil bath air cleaner.
Hey Kevin, did it work for you? I have a 79 international with hydrovac booster and can’t find a replacement.
@@martingomez4216 Martin if you haven't, I would recommend gathering part numbers and calling Brake & Equipment Warehouse in Minneapolis. They may be able to rebuild it for you.
@@martingomez4216 I'm just going to run it with no booster and see how bad it is first.
@@SealedBeamRallyTeam no, mine has an FE v8, I am just going to try it out without a booster first and see how bad it is.
ed here, found rebuilt hydrovac at napa, all cyclinders 6 working, new master. still wont stop with load! wondering if drums worn out?
I assume the brake pedal depresses properly. Double check the vacuum lines?
@@SealedBeamRallyTeam yes, hard petal, took off drums and watched wheel cyclinders move but dont remember seeing both cycl. move on back wheels [top & bottom]
@@patriciareynolds2729 Check to make sure you're getting fluid. There could be a kink or the hose to the rear axle might be collapsed internally.
@@SealedBeamRallyTeam thank u, found kink and that helped. left rear brakes will lock but right wont.
@@patriciareynolds2729 You've replaced all the brake hoses?
I am considering buying a 66 Ford F700. The owner says it needs the brakes worked on. I called around and no one local will supply the parts. Do you know of any good online suppliers?
Check out my later video on brake installation, but here's the short of it
Napa has wheel cylinders, master cylinder, and hardware kits. They might be able to get a rebuilt hydrovac, but don't count on it. For shoe relining and drum turning, find a local brake specialist shop. I used Brake And Equipment Warehouse in Minneapolis. They had all the wheel cylinders and whatnot in stock as well, Raybestos brand. They sent my hydrovac to Texas to be rebuilt. Hard to find hydrovac parts but they still do exist! Consider a newer firewall mounted booster with dual master if you have the room- i didn't. I of course made all the lines by hand from nicopp.
@@SealedBeamRallyTeam Thanks. I checked Napa online but they didn't have anything listed so I might stop in the local shop to inquire. Maybe they can help with the pads and drums. Will look for a shop local that relines and turns as well.
@@timothyneiswander3151 If your local Napa can't find it, let me know and I can send you the part numbers
I'm putting a 2005 f550 rear axle in mine bought it today for 500 with almost new tires on it.
Bolt pattern and tire sizes match??
@@SealedBeamRallyTeam no I mean I took the whole rear axle out of my 1966 and replaced it with the 2005 f550 axle. It bolted right up. Perfect tire size now I think.
@@MrBlaze256 Did you use the F550 wheels/tires? Or widow makers? I really dig the 2 speed axle, so I'm looking eventually swap a T56 6-speed in, but I'm curious about the options.
@@SealedBeamRallyTeam i just have the f550 19.5 inch back rims on and leaving the front axle stock for now. Got to find some 19.5 rims for the front to match the rear. There is also an auxiliary transmission that adds a overdrive.
@@SealedBeamRallyTeam my truck doesn't have much power. It's either a 240 or 300 6 cylinder. I hope I can find a good deal on a diesel engine to put in it.
I'm in superior and nead your help
Brake And Equipment Warehouse in Minneapolis was my main source for brake parts, although NAPA can get a lot for it. Factory service manual is necessary.
Any specific problem you're having?
Diesels don't have any vacuum don't have anything to do with the turbos. Diesels don't have a throttle flap it's wide open all the time and the gas pedal just controls how much Diesel fuel gets injected
Good point! That combined with turbo gas engines would cover most of the engines in modern pickups.
Thank You sir for the informative and educational video. Keep up the good videos. Have A Good Day! 🛻🚚🚛
