Installing rear brake pads on a vehicle equipped with an integral parking brake may be difficult if you don’t know what you are doing.
For those who do not know an integral parking brake means that your caliper piston does two jobs. First it applies pressure to the pads when you press the brake pedal. Second it has a ratchet mechanism to apply pressure when you press the parking brake. How this system works is the caliper piston instead of just pushing out like it would on a normal system, rotates while it comes out. The rotation is how the parking brake applies. This is what makes changing brake pads difficult on these vehicles if you don’t have the correct tool. You need a tool that rotates and presses the piston in at the same time.
