1 x brake piston seal 1.125 for AP Racing classic caliper 3086

Bore size 1.125inch (28.6mm) CP4949-109

Fitting Instructions:

1. Soak new seals in brake fluid for minimum of 30 minutes.
   
2. Clean brake caliper with warm soapy water and dry off.
3. With the pads removed insert a brake disc or block into the centre of the caliper. Using either hydraulic pressure or compressed air carefully extend all pistons against the disc or block. Remove block and remove pistons. WARNING: Keep your hands and all body parts away from escaping high pressure air and caliper pistons.
4. Carefully remove old seals with a narrow blunt edged tool.
5. Ensure that caliper bores, seal grooves and pistons are clean and free from debris and moisture. Use only Alcohol based cleaning fluid, not Mineral oil.
6. Carefully fit replacement seal into groove in caliper body ensuring that it seats correctly in the groove. Check the seals are free from damage and correctly seated in the groove not twisted or kinked.
7. Carefully engage piston into the caliper bore and, using a suitable rigid flat bar to apply even pressure, push the piston fully into body.

N.B. Excessive force should not be necessary. If the piston does not slide smoothly into bore remove & check that the seal has been fitted correctly.
