Checking the parking brake system (BMW 5 Series E39)

The parking brake system of cars with disc brakes on the front and rear wheels consists of separate drum brakes installed on the rear wheels. Since the brake linings of the parking brake system in these models of cars practically do not wear out, it may happen that the brake drum begins to rust and the brake linings become covered with dirt. Therefore, before checking, it is recommended to perform the following actions.

On a still street or in a parking lot at a speed of approximately 40 km/h, carefully tighten the handbrake until the first signs of braking appear. Maintaining the speed, tighten the handbrake another notch and drive approximately 400 m. Release the handbrake and allow the brake mechanisms to cool down.

Raise the car from behind.

Place the handbrake lever in the 5th locking groove. Turn both wheels by hand. A slight braking action should be felt on the rear wheels.

Place the handbrake lever in the 6th locking groove. Now the rear wheels should be able to be turned by hand with sufficient force. If the handbrake needs to be tightened further before a noticeable braking effect is achieved, the parking brake system must be adjusted in accordance with the instructions in section "Brake system".

Lower the car.
