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).

Appreciate the help but now its all moot ans the priller is being put to sleep. Hell I may have a kegger and set it on fire LOL

I know a place we can do that.

Be better if its not around here, most of my neighbors think I am nuts anyway. Get the looks when I drive up blaring machinehead and fear factory in the car:rockwoot:

We can go to a place where no one would bat an eyelash at a massive flame.

at a kkk meeting lol

Well sure, but no.
