Great instructional video. Unfortunately my bolts were welded on and two of them were stripped by the 25x. Ended up being a hell of a job with blowtorches, diamond disc cutters, big screwdrivers and hammers all getting involved at one point or another!
I know that people are kind of poking fun at this video because of how basic it is, but having just had to pull off a disc that someone else had sheared the T25 interface on, I really feel like they could have done well to watch this.
+Kevin Dudd Cheers Kevin, we think theres a lot of little bits of knowledge within MTB mechanics that need passing on this way because the job seems so simple however it makes a lot of difference to do it the right way.
+Matthew Laidler Centerlock removes the danger of stripping a bolt's head, also ussualy centerlock hubs are lighter and it uses the same key as a cassete removal tool (some of them).
Centre locks provide even tension across the whole rotor. If a six bolt rotor isn't tightened properly or if it isn't checked periodically the bolts can work themselves loose and can end pretty badly
I was trying to do this to my bike but the dice has no hex bolts .they look like there rivited on .do I need to replace the hub .IAM not sure ant info would be great 👍
I just got new disk for my bike and they don't have anything engraved into them. I'm not sure what side to put them on. Also they didn't come with any papers or instructions. Thank you in advance.
As a former shop mechanic, I watch these to see what they may or may not be doing differently than the way I was trained. Sometimes I see something that makes me slap my head because the way they do it is so much simpler.
I got new brake pads and they are howling like a wolf pack on a full moon. What's the solution? Should I use some cleaner and degreaser? It might even also be the pads. How could I get those dry?
+Tyler Lovejoy you could clean your rotor, spray it on to a dry cloth and thoroughly clean the rotor. It could be from the heat they have become glazed, why not try some emery paper to take the surface off the pads and rotor? Cheers... Scott
Anyone else had trouble with very loud squealing Avid Clear Sweep 180 front disc? Well......I changed mine for an Onoff Components 160 with Onoff Components organic pads. I took out that 20mm spacer (obviously). After a few 'emergency stops', et viola, silence is golden! I was worried about under braking at the front end, but no problems so far except that even pressure on both brake leavers occasionally locks up the rear wheel first. So changing a disc could be part of a brake silencing plan after you've tried everything else. New discs should come with pre-coated torx screws.....handy.
#askgmbn I want to upgrade my 180mm front rotor to a 203mm rotor. Can't find anything in the owners manual about it, is it safe for the frame? Bike is a Kona precept 130. Thx :)
+Oli Taylor I started just over 2 years ago, in my local shop (well, 30 miles) as an unpaid trainee. Now I'm a level 3 mechanic and have contacts all over the place, be that reps from distributors or race team mechanics. It's a small industry, and most people are happy to teach if you're happy to learn. If you show promise, and make an effort to impress, then you'll get on fine
All the comments about people shearing the T25 bolts. Please don't use cheap torx bits like you get from wilko or b&m. Draper or hilti or better work so much better. The cheap ones are made from cheaper materials and easily chip and don't bite in correctly. That's the experience I've had working with these types of bolts and fixings for 20 years now 😇
Like everything else they get worn down and loose performance! a 'braking groove' can form meaning that when you replace pads not all f the surface is used effectively
So much hate in these comments now. Lay off the lads, if they covered every race on the calendar as well as videos on every little thing you can imagine then they'd be stuck even finding time to get out and ride for themselves.
I've heard that you shouldn't touch the rotors with your bare hands, otherwise the oils on your fingers will contaminate the rotors, thereby decreasing brake strength and making them noisy.
+Global Mountain Bike Network Ah okay. Just curious though, but in my opinion, I think touching the rotors reduces the effectiveness of the brakes itself. Thanks for replying
+Alphonse Gabriel As Scott just demonstrated, it literally takes 5 mins to change 2 rotors. Going to a lbs for that would just be a waste of everyone's time
Are you kidding? What's next? How to remove a saddle? How to sit on a bike? Buy some tickets to the south of spain, ride the shit out of local trails and make useful videos please.
stupid video.. whoes rotor isnt near impossible to remove due to excessive locktite... you literally skipped the only difficult part where tips and tricks would b helpful..

He is doing it much better now. Gaining self confidence. Good job mate.
where was he weak and not confident?

Well you made it look easy to remove the rotor,In my 2 mtb rotors are very tight i broke 2 🛠 and damage one screw already
No star pattern for tightening up the rotor bolts?
+MatadorCE He said he does every second bolt which is basically the same thing, assuming he goes round 1, 3, 5, 2, 4, 6 until they're all tight
+MatadorCE he also forgot to apply medium strength Loc Tite.
+MatadorCE went for every second bolt pattern, similar to the star pattern...
Great explanation. Big thanks to you.
Does the directionality of the rotor really affect heat dispersion? I thought it would have more to do with mechanical stress.
I know that people are kind of poking fun at this video because of how basic it is, but having just had to pull off a disc that someone else had sheared the T25 interface on, I really feel like they could have done well to watch this.

Hey GMBN, I got a tip for ya, How about washing a whole wheel before installing a rotor?
I agree if your gonna change it clean what you can get at while it's off
Can you do a video on servicing the rear shock or front fork? Thanks.
where can I get the centre lock removal tool you are using cheers
This made my allen key smooth
Hey Scott, when do you use loctite and when do you use regular grease on the thread?
Are centre lock disks better than 6 bolt or is it just two different ways of doing the same job
+Matthew Laidler Centerlock removes the danger of stripping a bolt's head, also ussualy centerlock hubs are lighter and it uses the same key as a cassete removal tool (some of them).
Centre locks provide even tension across the whole rotor. If a six bolt rotor isn't tightened properly or if it isn't checked periodically the bolts can work themselves loose and can end pretty badly
I was trying to do this to my bike but the dice has no hex bolts .they look like there rivited on .do I need to replace the hub .IAM not sure ant info would be great 👍
Can i attach a pannier rack?
Is it the same for the back rotor?
Do i need new Hubs/wheels if i want to fit discs on my bike
I just got new disk for my bike and they don't have anything engraved into them. I'm not sure what side to put them on. Also they didn't come with any papers or instructions. Thank you in advance.
I think my bike has central lock system and I just got 2 new rotors in the mail with 6 bolts each. Do I have to return it??? :(
Next up: how to pull in your brake levers "like a pro"
+Justin F They already done that video :)

whats it called ?

do i really need to torque them up? what if i just get them tight?

What means adult. my size should be around 27 inches wheels and 18 inches frame. help me to choose the right size. i'm 5.7
What size of t25 torx key i need. Theyre is like x1, x2
Thanks, bro!

even though you guys are good with bikes ...but i have never seen you guys bleed hope tech 3 brakes only shimano?
+Gareth Davies Avid is up next!!!
+Global Mountain Bike Network is hope after them?
My ceterlock Shimano XT discs came with nuts that had to be assembled with a Kassette-tool.
Nice subject ..............................
I'm only 16 but my dream job is being a bike mechanic for one of the race teams. any tips on where to start?
Start in a local shop, offer to do some hours for free, it's a foot in the door in the industry
+Chris Henry thank you, I've been trying to get a job in my local trail centre but not heard anything yet. But thanks

+Chris Henry Thank you, I'll see what happens now as to whether I look somewhere else
+Oli Taylor Wages are awful just don't bother
what happened to buying a second hand bike

What is the point in replacing brake rotors
Like everything else they get worn down and loose performance! a 'braking groove' can form meaning that when you replace pads not all f the surface is used effectively
Global Mountain Bike Network how often should an enduro rider replace the rotors / how can you tell
Mine are hold up by rivets how will I remove them then?
My are to.not sure if we would have to replace hub to do it
3:36 Never grab a spoke.
Wonder how your rim got bent?
Hey guys, my most recent video is raw mountain biking! Really proud of it, and I would highly appreciate if you gave it a check, cheers!
So much hate in these comments now. Lay off the lads, if they covered every race on the calendar as well as videos on every little thing you can imagine then they'd be stuck even finding time to get out and ride for themselves.
Must need a better tool as everytime i try to get the bolts i brake the tool
Instead of disk break cleaner use pure alcohol and make sure you dont drink it all :)
I'd let Scott work on my bike
+JD Walter bring it to the GMBN HQ...
Why are my bolts so fucking tight?
I've heard that you shouldn't touch the rotors with your bare hands, otherwise the oils on your fingers will contaminate the rotors, thereby decreasing brake strength and making them noisy.
yeh u shld wear gloves when doing this
+John May correct that's why at the end we cleaned the rotor again...
+Global Mountain Bike Network Ah okay. Just curious though, but in my opinion, I think touching the rotors reduces the effectiveness of the brakes itself. Thanks for replying
+John May certainly would but if you clean it afterwards with disc cleaner then no problem!!!
+Global Mountain Bike Network Okay, makes perfect sense now. Sorry if I was being a nuisance or anything like that
You guys do realize its the 2nd year that you managed to not cover the Cape Epic? Tour de France of mountain biking? Sigh
GMBN,please invest in good microphones ffs,geeeeeez
Can't we just call 'em discs?
Support your local Bike shop.........Just Saying!!
+Alphonse Gabriel As Scott just demonstrated, it literally takes 5 mins to change 2 rotors. Going to a lbs for that would just be a waste of everyone's time
+SmevMev Thats simply not true, yeah and in five minutes some dudes fuck up big time believe me.
+Alphonse Gabriel to your lbs to losen some bolts? Hahaha...
+jutech1 Not me, but others who are ham fisted and fuck the bike up and expect the shop to sort it out , of course garantie!!!!!!!!!!!!!!!!
Not all bike shops are quality. Trust yourself to do things right, trust gmbn.
Are you kidding? What's next? How to remove a saddle? How to sit on a bike? Buy some tickets to the south of spain, ride the shit out of local trails and make useful videos please.
+spybot2d grated it might be a easy task to many a home mechanic however it wasn't the first time that this was requested by our viewers...
+spybot2d dont like it dont watch it jerk
if you already know how to why watch this video fk off m8, Thanks GMBN for making these videos they are very helpful!
spybot2d fuck urself I found this useful for my own reasons
stupid video.. whoes rotor isnt near impossible to remove due to excessive locktite... you literally skipped the only difficult part where tips and tricks would b helpful..
this guy is the reason why I don't watch GMBN...such anoing guy...just one look at him and I can tell that he's reading from script...
You guys do realize its the 2nd year that you managed to not cover the Cape Epic? Tour de France of mountain biking? Sigh
+Hayden Napier it's in the DSS this week as a wrap up!
