new ones.

Reassembly

1. Install caliper body.

2. Install bleeder with cap and tighten the cap to the

specified torque.

Torque: 8 N·m (69 lb in)

3. Apply special rubber grease to the piston seal and

cylinder wall, then insert the piston seal into the
cylinder. The special rubber grease is included in
the repair kit.

Brake Pads Inspection

Check the outer pads by looking at each caliper from
above. Check the thickness on the inner pad by looking
down through the inspection hole in the top of the
caliper. Whenever the pad is worn to about the
thickness of the pad base, the pad should be removed
for further measurements. The pad should be replaced
anytime the pad thickness (1) is worn to within 1.0 mm
(0.039 in) of the pad itself.
Wear indicators are installed on disc brake pads, disc
brake pads need replacement when the wear
indicator is heard.

Minimum limit (1): 1.0 mm (0.039 in)
