Before the handbrake shoes can be replaced, the assembly mode must be activated. This is done to facilitate removal of the brake disc and to prevent damage to the handbrake mechanism. After replacement, the start-up, parking brake and brake bedding-in functions must be run. The start-up and parking brake steps are only applicable to E70.
Test conditions:
Engine off, ignition on.
No faults in the system.
Procedure:
To activate the assembly position, select the "Set assembly mode" function and follow the instructions.
To deactivate the assembly position, select the "Cancel assembly mode" function and follow the instructions.
If deactivation is not possible, it will occur automatically when the vehicle is driven faster than 3 km/h to prevent the loss of braking effect.
