Frequently asked questions

How do I know if my brake pump is faulty?
A spongy pedal, a leak or a loss of pressure are the usual signs. Have the whole circuit checked before going back on track.

Can a pump be repaired with a seal kit?
When the body is sound, replacing the seals is often enough. Otherwise, a complete replacement is safer.
