Removing
Instructions: Before disconnecting the connector, turn off the ignition and wait at least 30 seconds.
Disconnect connector -1- from parking brake motor.
Unscrew both Torx bolts -arrows- for parking brake motor. Remove the parking brake motor from the brake caliper. Remove sealing ring.
When doing this, make sure that the annular groove of the sealing ring and the mating surfaces of the parking brake motor are not damaged. Clean the annular groove and mating surface of the parking brake motor.
Installation
Lightly lubricate the new O-ring with brake fluid before installing. Turn the spindle back a little using the 8 mm polygon -A- so that the handbrake motor can be installed correctly.
Caution: Do not unscrew the O-ring while installing the parking brake motor.
Carefully install the parking brake motor, properly fitting the O-ring. Turn the parking brake motor so that the holes for its mounting bolts and the threaded holes in the caliper match. In this case, it is necessary to ensure a tight fit of the parking brake motor to the brake caliper. Never press the parking brake motor into the brake caliper using the mounting bolts. Screw in Torx bolts -arrows- by hand and then tighten. Connect connector. Carry out the basic setting of the brake system. Connect tester -VAS 5051- and select function.
