fingers.
2. Carefully depress the brake pedal to hydraulically push piston out of its bore. Once completed, apply and hold down the brake pedal to any
position beyond the first inch of pedal travel using a brake pedal holding tool. This will prevent the fluid in the master cylinder reservoir from
completely draining out.
3. Disconnect the brake fluid flex hose from the caliper assembly and remove it from the vehicle.
CAUTION: Do not use excessive force when clamping caliper in vise. Excessive vise pressure will cause bore distortion.
4. Mount the caliper in a vise equipped with protective jaws.
5. Remove the piston dust boot from the caliper and discard.
NOTE: Do not use a screw driver or other metal tool for seal removal. Using such tools can scratch the bore or leave burrs on the seal groove
edges.
6. Using a soft tool such as a plastic trim stick, work the piston seal out of its groove in caliper piston bore . Discard the old seal.
7. Clean the piston bore and drilled passage ways using alcohol or a suitable solvent. Wipe it dry using only a lint-free cloth.
8. Inspect the piston bore for scoring or pitting. Bores that show light scratches or corrosion can usually be cleared of the light scratches or corrosion
using crocus cloth.
