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, integrated with the wheel hub. The brake discs are solid on the rear axle.
The brake caliper (1) comprises two halves joined with screws, positioned over the brake disc. 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 armature, which is secured to the wheel spindle.
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 inner brake pad against the brake discs. On account of the action-reaction principle the brake caliper (1) is pressed backwards. This movement presses the outer brake pad against the brake disc. (Also, see FOOT BRAKE AND PARKING BRAKE .) The sliding brake caliper's retainer (2) presses the outer brake pad against the brake disc.
The dust boot prevents dirt getting in between the cylinder and piston.
Old brake calipers at the rear are replaced with new calipers filled with brake fluid from the factory. This simplifies bleeding.
The splash guard prevents water and salt from soiling the brake disc. Any soiling results in reduced friction and hence reduced braking power.
