Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.

The vehicle has disc brakes on all four wheels to ensure optimum braking performance. The foot brake is combined with the parking brake on the rear axle.
The brake discs are ventilated on the front axle and are available in different diameters depending on engine type. There are three different types of rear brake discs.
- ventilated disc for electric parking brake
- solid disc for electric parking brake
- solid disc for foot operated mechanical parking brake.
The brake caliper (1) consists of two parts, housing and holder. The caliper grips across the disc brake and slides in the holder on two sliding pins (4). The sliding pins are greased and protected with a rubber bushing (3). The braking force from the brake pads (5) is absorbed via the holder (2), which transfers the force to the spindle.
The sliding pins are made of steel. They are screwed into the holder, which is secured to the stub axle.
The brake caliper contains a piston (8) together with a sealing ring (10) and dust boot (11). The piston cylinder is made of steel.
The piston presses directly on the internal brake pad. Based on the action-reaction principle, the caliper (1) presses backwards. Through this movement, the outer brake pad presses against the brake disc.
