Oiwa Garage Tech Note
"This is the front brake caliper seal kit. Inspect the bore for pitting before resealing; a marked bore will not hold a new seal. Bleed the brakes and confirm a firm pedal before driving."
Frequently Asked Questions
How do I know the caliper seals are done?
Fluid weeping at the caliper and a sticking or dragging front brake point to failed seals. Check the bore for pitting before you reseal.
Should I check the bore before resealing?
Yes. Inspect the caliper bore for pitting before you reseal; a pitted bore needs a caliper, not a seal kit.
Do I need to bleed the brakes after?
Yes - any time you open the caliper, bleed that corner and confirm a firm pedal before driving.
