PEDAL STROKE

Operate parking brake pedal with a force of 196 N (20 kg, 44 lb), make sure pedal stroke is within the
specified number of notches. (Check it by listening and counting ratchet clicks.)
INSPECT COMPONENTS

Make sure that the mounting conditions (looseness, backlash, etc.) of each component are normal.

Check the following:
–Device assembly for bend, damage and cracks. Replace if there are.
–Cables and equalizer for wear and damage. Replace if there are.
–Parking brake switch. Replace if it does not work correctly.
ADJUSTMENT

To perform adjustment operations, remove rear tires from vehicle with power tool.
1. Insert a deep socket wrench onto adjusting nut. Rotate adjusting
nut to fully loosen cable, and then release parking brake pedal.
2. Secure disc rotor to hub using wheel nut so as not to tilt disc
rotor.
3. Remove adjuster hole plug installed on the disc rotor. Turn the
adjuster in direction “A” using a flat-bladed screwdriver as
shown, until disc rotor is locked. Turn the adjuster in the oppo-
site direction by 5 or 6 notches after locking.
4. Rotate disc rotor to make sure that there is no drag. Install the
adjuster hole plug.
5. Adjust parking brake cable with the following procedure.
a. Operate parking brake pedal 10 or more times with the force of
full stroke.
b. Rotate adjusting nut to adjust parking brake pedal stroke using a
deep socket wrench.
CAUTION:
Do not reuse adjusting nut after removing it.
c. Operate parking brake pedal with a force of 196 N (20 kg, 44 lb), make sure the pedal stroke is within the
specified number of notches. (Check it by listening and counting ratchet clicks.)
