Before the new handbrake cable is installed and adjusted, the mechanical adjustment devices in the two brake callipers of the rear axle should first be checked and reset. Correct adjustment of the parking brake is only possible if the parking brake Bowden cables and all moving parts of the parking brake move easily and are functional.
To do this, remove the brake calliper and operate the mechanical lever on the brake calliper until the brake piston extends slightly. After successful testing, turn the piston back completely using a reset tool (Figure 3).
While this task is being carried out, all other components such as brake blocks/pads or guide bolts should be checked for wear and functionality at the same time. Worn or defective components should be replaced.
Put brake callipers back together and reinstall. Then bring the brake pistons into their working position by means of light pedal pumping.
