Pre-procedure1
Enter rear brake pad replacement mode.
- HINT:
Turn the ignition switch off.
Procedure1
Check that the rotating parts are not seized or the actuator is not spinning freely.
Check that the parking brake actuator assembly LH is installed properly to the rear brake caliper and that it is not spinning freely.
- HINT:
-
For the parking brake actuator assembly LH removal procedure: Click here
Check that there is no damage to the rotating parts from the parking brake actuator assembly LH to the rear brake caliper.
Inspect the parking brake actuator assembly LH and check that it operates correctly.
Check that the rear brake caliper threaded part rotates and that the rear disc brake piston moves outward.
- HINT:
-
For the check procedures, refer to the parking brake forced release method when not using the GTS.
- Result:
Result Proceed to Parking brake actuator assembly LH is malfunctioning A Other than parking brake actuator assembly LH is malfunctioning B
Post-procedure1
Return to normal mode after work is complete.
