brake cleaning - Page 2

Brake cleaner. Brake dust turns into a sticky powder type mess. Just unbolt them and get a bucket. Slide a caliper in the bucket and go to town on it. Do your best to not hose down the brake line or the rubber boot/s too much.

I've cleaned mine before. I use a biodegradable bike wash. Unbolted the caliper, squeeze the lever just enough to expose clean piston and scrub those babies. Worked great.

Why the fuck are you riding your bike in wet concrete you silly goose?

Could also be the fork alignment. When replacing the front wheel, the axle bolts could be tightened too much. Or a spacer in the wrong position. The bottom of the forks would then be closer together than the top. This binds the fork movement up and down, and could cause the calipers to bind.

I measured the distance between forks on my old Suzuki decades ago with a set of calipers. I had to shim the axle to get the fork distance perfect, and the rotors equal distance from the forks. I haven't had to replace the fork seals on it in 45K miles. And the brake pads just skim the rotors. But I bet if I took out those shims, the brake pads would bind against the rotors, and the forks would bind.

But would that happen out of nowhere? I replaced the steering head bearings at the start of the season and the front wheel bearings soon after. I have about 5k on the clock so far this season and it just started up a few days ago after an oil change. I didnt touch the front end though.

just heard from af1. they tell me neither brembo or aprilia makes a rebuild kit and that you need to buy a new caliper. Unfrekin believable.
