Skorp Posted April 4, 2012 Report Share Posted April 4, 2012 Use CRC BrakCleen when its dirty. I have one in my car to use when the bike gets road dust on it. or to use when i ride on dry dirt. If you have oil on your pads or disc, you have to cook them. I normally use a metal plate and a torch. Cook it until it doesn't smoke anymore. You can also use a cooking plate.

JD™ Posted April 4, 2012 Report Share Posted April 4, 2012 All about boiling discs, then chucking them in the oven for a bit. With pads, chuck them in a bath of meths, and light the b*****d. Just remembered I've got to do the same to both of mine before Friday, so I might even remember to do a little 'how to' for the amount of times this gets asked Quote Link to comment Share on other sites More sharing options...
the mysterious leemur Posted April 4, 2012 Report Share Posted April 4, 2012 A favorite of mine is to get an old metal water bottle , put in some sort of flammable material put the backs in and set it on fire . For cleaning a disk just put it in boiling water , wipe it with a cloth and if you want a light bit of sanding if you want to and wash both off after .

xTrials_Rider Posted April 4, 2012 Author Report Share Posted April 4, 2012 thanks, i boiled the dics and then wiped it, i "cooked" the pads and put them on and went out to test how they work and they dont seem to bite, i pull the lever right in and the bike keeps rolling any advice?

Each time you change anything about the pads or rotors, you'll have to bed the brake back in. Time to find yourself a big hill and take a bottle of water with you! Ride down hill, do a mix of sharp stops and dragging the brake. Splash water over rotor and pads while you walk back up the hill to repeat. Then again, being able to pull the lever to the bars sounds like it needs a bleed anyway. Quote Link to comment Share on other sites More sharing options...

Make sure the pads and roter are cool before doing this as if they are hot and you put water on them it can "glaze" the pas and decrease performance.

xTrials_Rider Posted April 4, 2012 Author Report Share Posted April 4, 2012 so: 1. go down a hill while holding the brake in 2. wait till the pads and disc are cooled down 3. splash water on both 4. back up the hill and repeat everything again?

the mysterious leemur Posted April 4, 2012 Report Share Posted April 4, 2012 (edited) I'd personally put the water on at the top of the hill personally . Apart from that , it's fine Edited April 4, 2012 by the mysterious leemur Quote Link to comment Share on other sites More sharing options...

Depends on the length of the hill You'll know when they're getting there though, because of the changing feeling of power. I wouldn't worry about the glazing comment either - I've always had my previous discs (albeit not on trials bike) steaming away while bedding in and never glazed them. That's the point of the mix of short sharp stops and dragging the brake. Quote Link to comment Share on other sites More sharing options...

the mysterious leemur Posted April 4, 2012 Report Share Posted April 4, 2012 Just want to add glazing only happens on certain pads , I believe it's on organic compounds that it affects Quote Link to comment Share on other sites More sharing options...

How Original Posted April 4, 2012 Report Share Posted April 4, 2012 This also may be wrong, but I was told if the brake squeaks then it's still a bit warm, so perhaps wait until it stops squeaking then put water on and back down you go.

My hopes , maguras and echos have only squeaked when wet Quote Link to comment Share on other sites More sharing options...
How Original Posted April 4, 2012 Report Share Posted April 4, 2012 My hopes , maguras and echos have only squeaked when wet I think I was chatting sh!t then But nah they will squeak in the wet anyway. They're having to work harder. Quote Link to comment Share on other sites More sharing options...
Rockman Posted April 4, 2012 Report Share Posted April 4, 2012 Don't cook your pads or blowtorch them, this can weaken the bond between the material and backing.. which means the material might rip off the backing.. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted April 4, 2012 Report Share Posted April 4, 2012 The bedding in process serves a couple of main purposes; - To get everything running perfectly straight (though most of this should be done when installing the brake obviously!) - To deposit a small amount of pad material around the rotor which helps boost braking Short sharp burst are great but try to combine them with some more constant, progressive braking too for better results Quote Link to comment Share on other sites More sharing options...
the mysterious leemur Posted April 4, 2012 Report Share Posted April 4, 2012 Another tip for disk brakes : Don't try cutting some TNN LGM compound and glueing it to a disk pad backing and using it , it works amazingly well for a small time but then it burns :$ Quote Link to comment Share on other sites More sharing options...
