Frequently Asked Questions
How do I know this caliper seal is bad?
Fluid weeping at the caliper and a brake that drags point to a failed seal. Inspect the bore for pitting before fitting the new seal.
Should I check the bore before resealing?
Yes. Inspect the caliper bore for pitting first - a marked bore will not hold a new seal and needs a caliper instead.
