Frequently asked questions

My caliper is leaking, what should I do?
A leak usually comes from a piston seal or a fitting. Replace the seals or the caliper concerned, then bleed the circuit before going back on track.

How do I know if my caliper is compatible?
Compare the reference and the mounting centre distance with those of your original caliper, and check the disc diameter. If in doubt, contact us.
