chuck your pads in a pot of boiling water for a bit- they may have iol and greasy shit on them then give them another go. If they still squeek, chuck mud and sand and stuff on the rotor.

I had my pads 3 cm over a flame today, is that enough? also with the water bit.. do i leave it in the water then boil, or should i chuck it in after the water is boiling and for how long?

How old are the brakes? Mine started doing that when I'd had them for a couple of months...

Burn, boil, bake, fry or stew your pads at your own risk. It is really not a sound procedure and I would advise dishing out for some new pads; that's if they actually are contaminated, some just squeak, live with it.



PS: Bring on the "I stewed all the pads I've ever owned!" responses, we know you can get away with it but IMO it just isn't worth the risk.

To clean your disks you can used brake cleaner (available from servo's) or carburettor cleaner. using some rubber gloves isn't wimpy with these things, esp the carburettor cleaner. The disks may alsoo like a light sanding, just to get the shine off, say P120 paper. But disks go for ages.
What is more common is the pads become glazed. Pull them out of the the caliper, and rub them against some concreate (it's gotta be rough, not the polished kind). This is like sanding the pads, but it has to be against a firm, flat suface, you can't do it with paper in your hand. Bike pads are relitivley hard, so it'll take a bit of force, but you'll see as soon as the pads are clean.

Quick way, as Rik said, put some water on your disks, throw some building sand on them, and ride for a bit. I think that worked well for him last week.

Good luck.

Be careful using auto dick cleaner. Bicycle disks don't get anywhere near as hot as car ones, so there can sometimes be a residue left from the car cleaner on the rotors which is not cool. Isopropyl is always a safe bet.

Yeah, if you buy car products, don't skimp. Use a brand like Wurth, otherwise yoiu may get an oily residue, which won't help you at all!
