REPAIR PROCEDURE
1. Remove some brake fluid from the master cylinder.
2. Raise and support the vehicle.
3. Remove the front wheels.
4. Remove the front brake hose mounting bolt.
5. Remove the brake caliper lower flange bolt, then pivot the caliper up out of the way.
6. Remove the front brake pads, the shims, and the retainers.
7. Check the brake disc thickness.
Maximum refinishing limit
138
26.0 mm (1.02 in)
8. If the disc is within the service limit for refinishing, refinish it with a Honda-approved commercially available on-car brake lathe. If the disc is
not within the service limit, replace it.
9. Apply a thin coat of M-77 assembly paste to the retainer mating surface of the caliper bracket.
10. Install the pad retainers, then wipe off any excess assembly paste.
11. Mount the brake caliper piston compressor tool on the caliper body.
12. Press in the piston with the compressor tool so the caliper will fit over the brake pads. Make sure the piston boot is in position to prevent
damaging it when pivoting the caliper down.
13. Apply a thin coat of M-77 assembly paste to the pad side of the shim, and to the back of the brake pads.
14. Install the new brake pads, shims, and V-springs.
15. Pivot the caliper down into position. Install the flange bolt, and torque it while holding the caliper pin with a wrench, being careful not to
damage the caliper pin boot.
16. Reinstall the brake hose mounting bolt.
17. Repeat steps 4 thru 16 for the other side.
18. Install the front wheels.
19. Lower the vehicle.
20. Press the brake pedal several times to make sure the brakes work.
NOTE
Brake engagement may require a greater pedal stroke immediately after the brake pads have been replaced. Several applications of the
139
brake pedal will restore the normal brake pedal stroke.
21. Add brake fluid as needed.
22. Test-drive the vehicle, and check for judder or squealing.
