FRONT DISC BRAKE
BRAKE PAD
BRAKE PAD : Inspection and AdjustmentINFOID:0000000003811179
INSPECTION
Check brake pad wear thickness from an inspection hole on cylinder
body. Check using a scale if necessary.
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.
DISC ROTOR
DISC ROTOR : Inspection and AdjustmentINFOID:0000000003811180
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 FA X - 6 , "
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.

FUNCTION
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
SELF DIAGNOSTIC RESULT
Operation Procedure
Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for approxi-
mately 1 minute.
Display Item List
Refer to BRC-48, "DTC No. Index".
How to Erase Self-diagnosis Results
After erasing DTC memory, start the engine and drive the vehicle at 30 km/h (19 MPH) or more for approxi-
mately 1 minute as the final inspection, and make sure that the ABS warning lamp and brake warning lamp
turn OFF.
CAUTION:
If memory cannot be erased, perform applicable diagnosis.
NOTE:
 When the wheel sensor malfunctions, after inspecting the wheel sensor system, ABS warning lamp and
brake warning lamp will not turn OFF even when the system is normal unless the vehicle is driven at approx-
imately 30 km/h (19 MPH) or more for approximately 1 minute.
 Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or in case of brake
fluid level switch operation (when brake fluid is insufficient).
