"Component" .
CAUTION:
Before installing torque member to vehicle, wipe oil and grease on mounting surface of steering
knuckle and torque member.
2. Install brake hose to caliper assembly. Refer to BR-14, "
Hydraulic Circuit" .
3. Refill with new brake fluid and bleed air. Refer to BR-8, "
Bleeding Brake System" .
4. Check front disc brake for drag.
5. Install tires to the vehicle.
Brake BurnishingINFOID:0000000001717009
Burnish the new braking surfaces according to following procedure after refinishing or replacing disc rotors,
pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Be careful of vehicle speed because brake does not operate easily until pad 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 pedal for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.

3. Drain brake fluid. Refer to BR-8, "Bleeding Brake System".
4. Remove connecting bolt and torque member bolts using power tool, and remove cylinder body.
5. Remove caliper and disc rotor. If the disc rotor cannot be removed, remove as follows:
Make sure parking brake lever is completely disengaged.
Hold down the disc rotor with the wheel nut and remove the
adjuster hole plug.
Insert a flat-bladed screwdriver through the plug opening and
rotate the star wheel on the adjuster assembly in the direction
shown to loosen and retract the brake shoes.
Prior to removing disc rotor, make alignment mark using a
marker between the hub and disc rotor.
Remove wheel nut and rotor.
INSTALLATION
CAUTION:
Refill with new brake fluid. Refer to MA-19, "
Fluids and Lubricants".
Never reuse drained brake fluid.
1. Install disc rotor.
Align marks made during removal on the hub and disc rotor.
2. Install cylinder body to the vehicle, and tighten torque member bolts to the specification. Refer to BR-27,
"Component".
CAUTION:
Before installing cylinder body to the vehicle, wipe off oil and grease on washer seats on axle
assembly and mounting surface of cylinder body.
3. Install brake hose to cylinder body and tighten connecting bolt to the specification. Refer to BR-27, "
Com-
ponent".
CAUTION:
Do not reuse the copper washer for connecting bolts.
Securely attach brake hose to protrusion on cylinder body.
4. Add new brake fluid and bleed air. Refer to BR-8, "
Bleeding Brake System".
5. Install master cylinder reservoir cap.
6. Adjust the parking brake. Refer to PB-4, "
On-Vehicle Service".
7. Attach the tires to the vehicle. Refer to WT-6, "
Rotation".
CAUTION:
Burnish the brake contact surfaces when refinishing or replacing brake rotors, after replacing pads, or
if a soft pedal occurs at very low mileage. Refer to BR-29, "
Brake Burnishing".
Brake BurnishingINFOID:0000000001724670
Burnish the brake contact surface according to the following procedure after refinishing or replacing rotors,
after replacing pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive the vehicle on a straight smooth road at 50 km/h (31 MPH).
2. Use medium brake pedal /foot effort to bring the vehicle to a complete stop from 50 km/h (31 MPH).
Adjust brake pedal /foot pressure such that vehicle stopping time equals 3 to 5 seconds.
3. To cool the brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.
4. Repeat steps 1 to 3, 10 times or more to complete the burnishing procedure.

3. Spin the wheel of the vehicle by hand and observe the red SENSOR indicator on the ABS active wheel
sensor tester. The red SENSOR indicator should flash on and off to indicate an output signal.
NOTE:
If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and
retest.
Does the ABS active wheel sensor tester detect a signal?
YES >> GO TO 3
NO >> Replace the wheel sensor. Refer to BRC-83, "
Removal and Installation".
3.CHECK TIRES
Check for inflation pressure, wear and size of each tire.
Are tire pressure and size correct and is tire wear within specifications?
