F.A.Q.

What should I do if the caliper has been in a crash?
Stop using it immediately. The caliper is a safety-critical part—send it for professional evaluation.

Can I repair the caliper?
Yes. Original replacement parts are available. Using non-original parts may compromise performance and void inspection.

What brake fluid should I use?
Use DOT 4 Accossato Racing Brake Fluid. DOT 5.1 may damage seals if left in the system after use.

How tight should I torque the bleed screw?
Tighten the bleed valve with a torque wrench to 8–10 Nm. Do not over-tighten by hand. After bleeding, clean the area with compressed air.
