Service Information

If no service information is available for repair of brake noise, follow the procedures:

1. Replace brake pads with the latest available part number.

- Chamfer (smooth out) edges of pad by about 2 mm before installing.

- Apply anti squeal high viscosity brake disc quieter on pads as directed by the product manufacturer.

2. Check rotors for wear and/or corrosion.

- If the rotors pass visual inspection, machine the rotors, applying a non directional swirl finish.

- Repair or replace rotors as necessary (see appropriate Shop Manual for rotor specification and service procedure).

Note:
Whenever possible, an on car lathe is recommended for machining rotors.

3. Apply Squeak Relief Spray on Brake Treatment on rotors as directed by the product manufacturer (available at most auto parts stores).

4. Perform "bedding in" procedure, as noted, to reduce brake noise and to make pads last longer.

A. From 30 to 40 mph, brake gently until the vehicle almost stops.

B. Resume normal speed for 30 to 40 seconds to cool the brakes.

C. Repeat steps A & B five times.

D. Accelerate vehicle to 55 mph and brake gently down to 20 mph.

E. Resume normal speed for 30 to 40 seconds to cool the brakes.

F. Repeat steps D & E five times to complete the "bedding in" procedure for reducing brake noise.
