Disassembly Procedure
Important:
*
Replace all the components included in the repair kits used to service this brake caliper.
*
Lubricate the rubber parts with Delco Supreme 11(R), GM P/N 12377967 (Canadian P/N 992667) or equivalent DOT-3 brake fluid from
a clean, sealed brake fluid container to make assembly easier.
*
If any hydraulic component is removed or disconnected, it may be necessary to bleed all or part of the brake system.
*
The torque values specified are for dry, non-lubricated fasteners.
*
Perform the service operations on a clean bench, free from all mineral oil materials.
Caution: Do not place your fingers in front of the piston in order to catch or protect the piston while applying compressed air. This could result
in serious injury.
1. Remove the brake caliper from the vehicle.
Notice: Use clean cloths to pad interior of caliper housing during piston removal. Use just enough air to ease the pistons out of the bores. If the
pistons are blown out, even with the padding provided, it may be damaged.
2. Remove the brake caliper piston from the caliper bore by directing low pressure compressed air into the caliper bore through the brake fluid inlet
hole.
