Brake test of the parking brake on the brake test stand (all-wheel drive)
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2023 BMW M5, 2022 BMW M5, 2021 BMW M5, 2020 BMW M5, and 2019 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.
- Position the vehicle with its rear axle on the brake test stand.
- Position the selector lever in selector lever position N (neutral).
- Run engine at idle speed.
The brake test stand starts automatically.
The control unit runs a plausibility check (comparison of wheel RPM) to identify within a few seconds that a vehicle is on the brake test stand and changes to brake test stand mode.
If brake test stand mode has been activated and the EMF actuators are open, the indicator light for the electromechanical parking brake (EMF) flashes slowly.
- Operate the parking brake button: apply brake pads
When brake test stand mode is active and the EMF actuators have been partly applied, the indicator light for the electromechanical parking brake (EMF) flashes quickly.
- Operating the parking brake button briefly several times: The brake force is increased until the maximum brake force is reached and if necessary, forces the vehicle out of the brake test stand.
- Read the maximum brake forces on the left and right.
- If necessary, release the parking brake button (1) .
This releases the parking brake.
- Shift the vehicle from the brake test stand.
Brake test stand mode is automatically quit upon driving off the brake test stand.
