InstallationNBBR0037CAUTION:
IRefill with new brake fluid ªDOT 3º.
INever reuse drained brake fluid.
1. Install caliper assembly.
2. Install brake hose to caliper securely.
3. Install all parts and secure all bolts.
4. Bleed air. Refer to ªBleeding Brake Systemº, BR-8.
Brake Burnishing ProcedureNBBR0086When experiencing soft brake pedal feel at very low mileage, or
after replacing the rotor, burnish the brake pad contact surfaces
according to the following procedures.
CAUTION:
Only perform this procedure under safe road and traffic con-
ditions. 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 sec-
onds.
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 burnish-
ing procedure.
