Disk Brake *break-in* questions

Hello,

I have been having all types of strange noises coming from my disc brakes(Avid Mech.), and i was told to correctly *break-in* the pads.... how exactly do I go about doing this? do i be gentle to them or should i ride down a hill and use them hard?
Thanks,
Kevin

hold the brakes and pedal around or ride down a steep hill and hold your brakes. That should break them in

My brakes do that all the time too. They also do it after I clean my bike (due to stuff dripping on the rims from the chain). I hardly notice it at all anymore.

Are these totally new brakes or just replacement pads? Just wondering if maybe they were setup wrong in the first place, or something to do with the pads. I've got Avid's and they have never made a sound except after going through water, and then just for a couple rotations.

New replacement pads, seems to me that when i'm gentle to them they scream at me and i try cleaning thema nd they groan at me so i guess i'll have to keep trying... but its not cheap replacing the pads... (25 a pair)

Thanks,
Kevin

I wonder about polishing the rotors. Like with fine emery paper. I know on car brakes when you replace the pads if you don't turn the rotors they squeak. You might try leaving a note to Avid on their site and ask them. DG

The best thing to do for bedding in Disc Brakes is to take a short ride with the brakes setup to rub the disk, take a few bottles of water with you and pour water over the caliper and disk. Repeat this a few times and hey presto! problem solved.

This is from the horses mouth so to speak, ie One of the blokes who runs Hope.

I'm with Campagfetishboy on this one. The best way to bed rim brakes in (thankyou Klein, good to know your sarcasm gland is in top shape ) is to keep 'em wet for a while, it allows the friction by-products and maybe some muck in the water to shape the blocks to the correct shape; sort of like grinding valves in with grinding paste .

HTH.
