OPERATION
Depress the brake pedal several times at 5-second intervals with the engine stopped. Start the engine with the
brake pedal fully depressed. Check that the clearance between brake pedal and dash lower panel decreases.
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.
AIR TIGHT
1. Run the engine at idle 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 each time the brake pedal is depressed when performing this operation.
2. 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 sec-
onds or more.

BRAKE PAD
BRAKE PAD : Inspection and Adjustment
INFOID:0000000009267529
INSPECTION
Check brake pad wear thickness from an inspection hole on cylinder
body. Check using a scale if necessary.
ADJUSTMENT
Burnish contact surfaces between disc rotor and brake pads according to the following procedure after refin-
ishing or replacing brake pads, or if a soft pedal occurs at very low mileage.
CAUTION:
• 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.
DISC ROTOR

INFOID:0000000009267530
INSPECTION
Appearance
Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace it if necessary. Refer to
BR-15, "DISC ROTOR : Inspection and Adjustment"
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.
.
3. Inspect the runout with a dial indicator to measure at 10 mm
(0.39 in) inside the disc edge.
4. Find the installation position that has a minimum runout by shift-
ing 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. Refinish or replace the disc rotor if the runout is outside the limit even after performing the above opera-
tion.
CAUTION:
If the thickness is less than wear thickness + 0.3 mm (0.012 in), replace the disc rotor. Refer to
37, "BRAKE CALIPER ASSEMBLY : Removal and Installation"

Thickness
Check the thickness of the disc rotor using a micrometer. Replace
the disc rotor if the thickness is below the wear limit. Refer to
.
ADJUSTMENT

INSPECTION
Brake Lining
1. Remove plug from back plate. Refer to
2. Check brake lining wear thickness (A) from an inspection hole
on back plate. Check using a scale necessary.
ADJUSTMENT
Burnish contact surfaces between brake lining and brake drum according to the following procedure after
refinishing or replacing brake lining, or if a soft pedal occurs at very low mileage.
CAUTION:
