Disc Parking Brake

(Figure 1) Parking Brake Free Travel Adjustment:

PARKING BRAKE FREE-TRAVEL
The adjustment process requires a second person to apply a light brake pedal load. Parking brake lever free-travel is set by the position of the adjuster screw (# 11 figure 1). Turning the adjuster screw clockwise increases the free-travel; turning the adjuster screw counterclockwise decreases the free-travel.
The inner and outer pad assemblies must be new or parallel to within 0.15 mm (0.006 inch). Parking brake adjustment is not valid with heavily tapered pad assemblies and may cause caliper/parking brake binding.

^ Inspect old inner and outer pad assemblies and replace with new ones if they are tapered.

^ Parking brake free-travel should only be changed if the caliper has been taken apart, or when the pad assemblies are replaced.

^ This adjustment will not correct a condition where parking brake actuator levers will not return to their stops.

ADJUSTMENT
1. Disconnect parking brake cable assembly and remove actuator lever return spring (# 4 figure 1).
2. Have an assistant apply light brake pedal load, enough to stop rotor from turning by hand. This takes up all clearances and ensures that components are correctly aligned.
3. Apply light pressure to parking brake actuator lever (# 5 figure 1).

Measure
Free-travel between parking brake actuator lever and caliper housing (# 14 figure 1) at point B. Free-travel must be 0.61 mm to 0.71 mm (0.024 inch to 0.028 inch).

4. If free-travel is incorrect, do the following:

a. Remove adjuster screw.
b. Clean thread adhesive residue from threads.
c. Coat threads with adhesive.
D. Screw in adjuster screw far enough to obtain 0.61 mm to 0.71 mm (0.024 inch to 0.028 inch) free-travel between parking brake actuator lever and caliper housing at point B.

5. Have assistant release brake pedal assembly, then apply brake pedal assembly firmly three times.
6. Recheck free-travel as described in steps 2 and 3 and adjust as necessary.
7. Install actuator lever return spring and parking brake cable assembly
