Disassembly and Assembly
Disassembly1. Remove the disc brake caliper.
2. Drain brake fluid from the disc brake caliper.
3. Secure the disc brake caliper in a vise.
4. Remove the caliper piston.
1. Place a wood block between the caliper bridge and the caliper piston.
2. Apply low air pressure to the fluid port of the disc brake caliper.
3. Force the caliper piston out to the wood block. Remove the wood block and the caliper piston.
5. Remove and discard the caliper piston seals and dust boots.
6. NOTE: Do not hone the caliper bores. Caliper pistons are not available for honed calipers.
If the front disc brake calipers are leaking, replace the caliper seal kits. If the caliper bores are damaged, replace the front disc brake caliper.
Assembly
CAUTION: Do not reuse piston seals or dust boots. Damage to the vehicle can occur.
NOTE: Use new brake fluid for assembly and bleeding of the brake system. If DOT 3 is not available use DOT 4 Brake Fluid Meeting Ford specification SAE-J-1704-DOT 4.
1. Lubricate with High Performance DOT 3 Motor Vehicle Brake Fluid C6AZ-19542-AB or DOT 3 equivalent meeting Ford specification ESA-M6C25-A, DOT 3, the following brake system components:
1. Piston dust boot.
2. Piston seal.
3. Caliper piston.
4. Caliper bore.
2. Install the caliper piston.
1. Install the caliper piston seal.
2. Install the caliper piston dust boot.
CAUTION: Use care when installing the caliper piston, or damage to the caliper piston seal or dust boot may occur.
3. Install the caliper piston into the caliper bore.
4. Press the caliper piston into the caliper bore. Use even pressure while making sure the piston does not cock.
3. Install the disc brake caliper.
