brake cleaning

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.

What?

That sounds like bullshit. Give me the specs on your bike, and I'll see if I can come up with something.

Rebuild kit? I don't know about Prilla's, but every caliper I ever took apart had a dust shield, square-edged O-ring, and piston(s). That's it. A Scotch Brite pad can be used to polish the piston (hopefully, there's no rust on it if you changed the fluid sometimes) and bore, soap and water to clean the dust shield, and a new O-ring (and I can't believe someone doesn't have new ones).

Oh, and my CBR uses pins that the pads slide on. They get wear-grooves and cause the pads to stick. If Aprilia uses a sliding pin or pins, replace that first.

That's whats usually in the rebuild kit (minus the piston).
