FRONT DISC BRAKE
Check the thickness of the disc rotor using a micrometer. Replace
the disc rotor if the thickness is below the wear limit.
ADJUSTMENT
CAUTION:
 Burnish contact surfaces between pads according to the following procedure after refinishing or
replacing pads, or if a soft pedal occurs at very low mileage.
 Be careful of vehicle speed because the brake does not operate firmly/securely until pads and disc
rotor are securely fitted.
 Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake for a few minutes to cool the brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.Limit

INSPECTION
Check brake pad wear thickness from an inspection hole on cylinder
body. Check using a scale if necessary.
ADJUSTMENT

 Burnish contact surfaces between pads according to the following procedure after refinishing or
replacing pads, or if a soft pedal occurs at very low mileage.
 Be careful of vehicle speed because the brake does not operate firmly/securely until pads and disc
rotor are securely fitted.

DISC ROTOR
DISC ROTOR : Inspection and AdjustmentINFOID:0000000003811182
INSPECTION
Appearance
Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace if there are any abnormal
conditions.
Runout
1. Fix the disc rotor to the wheel hub and bearing assembly with
wheel nuts (2 points at least).
2. Check the wheel bearing axial end play before the inspection.
Refer to RAX-3, "
Inspection".
3. Inspect the runout with a dial indicator to measured at 10 mm
(0.39 in) inside the disc edge.
4. Find the installation position with a minimum runout by shifting the disc rotor-to-wheel hub and bearing
assembly installation position by one hole at a time if the runout exceeds the limit value.
5. Replace or refinish the disc rotor if the runout is outside the limit even after performing the above opera-
tion.

BRAKE BOOSTER
 Idle the engine for 1 minute to apply vacuum to the brake booster,
and stop the engine. Then depress the brake pedal several times
at 5-second intervals until the accumulated vacuum is released to
atmospheric pressure. Check that the clearance between brake
pedal and dash lower panel gradually increases (A → B → C) each
time the brake pedal is depressed during this operation.
 Depress the brake pedal with the engine running. Then stop the
engine while holding down the brake pedal. Check that the brake
pedal stroke does not change after holding down the brake pedal
for 30 seconds or more.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. This is a normal phenomenon due
to the brake system operation.
ADJUSTMENT AFTER INSTALLATION
Perform the brake pedal adjustment after installing the brake pedal assembly. Refer to BR-6, "Inspection and
Adjustment".

FRONT DISC BRAKE
1. Install the pad retainer to the torque member if the pad retainers has been removed.
CAUTION:
 Securely assemble the pad retainers so that it will not be lifted up from the torque member.
 Never deform the pad retainers.
2. Apply copper based brake grease to the mating faces between the brake pads and pad retainers.
3. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to the mating faces between the brake
pads, shims and shim cover, and install them to the brake pad.
CAUTION:
Always replace the shims together with the shim cover when replacing the brake pad.
4. Install the cylinder body and brake pads to the torque member.
CAUTION:
 Never damage the piston boot.
 When replacing a pad with new one, check a brake fluid level in the reservoir tank because brake
fluid returns to master cylinder reservoir tank when pressing piston in.
NOTE:
Use a disc brake piston tool to easily press piston.
5. Install the lower sliding pin bolt and tighten it to the specified torque.
6. Depress the brake pedal several times to check that no drag feel is present for the front disc brake. Refer
to BR-34, "
BRAKE PAD : Inspection".
BRAKE PAD : InspectionINFOID:0000000003811206
INSPECTION AFTER REMOVAL
Replace the shims and the shim cover if rust is excessively attached.
