PEDAL STROKE
• When parking brake pedal is operated with the specified force, make sure the stroke is within the specified
number of notches. Check by listening and counting the ratchet clicks.
INSPECTION
• Make sure the components are attached properly, checking for looseness or backlash.
• Check parking brake pedal assembly for bends, damage and cracks, and replace if necessary.
• Check cable for wear and damage, and replace if necessary.
• Check parking brake warning lamp switch for malfunction, and replace if necessary. Refer to DI-27, "
Wiring
Diagram - WARN -".
ADJUSTMENT
1. Remove the lower instrument panel LH. Refer to IP-10, "Removal and Installation" .
2. Partially engage parking brake pedal to access adjusting nut.
3. Insert a deep socket wrench to rotate adjusting nut and loosen
cable sufficiently. Then, disengage the parking brake pedal.
4. Remove the wheel and tire using power tool.
5. Remove the disc rotor and measure inner diameter at widest
point using Tool.
6. Transfer measurement less 0.6 mm to the parking brake shoes
and adjust accordingly.
7. Using wheel nuts, secure the disc to the hub to prevent it from
tilting.
8. Rotate the disc rotor to make sure there is no drag.
9. Adjust cable as follows:
a. Operate pedal 10 or more times with a force of 490 N (50 kg-f,
110 lb-f).
b. Rotate adjusting nut with deep socket to adjust pedal stroke to
specification.
c. With parking brake pedal completely disengaged, make sure
there is no drag on the parking brake.
10. Install the disc rotor.
11. Install the wheel and tire using power tool.
12. Install the lower instrument panel LH. Refer to IP-10, "
Removal and Installation" . Pedal stroke : 3 − 4 notches [under force of 196 N (20.0 kg-f, 44.1 lb-f)]
