34 00 009 Checking brakes on test stand

WARNING: This page is about a different car, the 2005 BMW 645Ci and 2004 BMW 645Ci. However, it is still accessible from the selected car via links, so may be relevant.

Necessary preliminary tasks:

Check tires for damage
Check tire treads
Check tire pressure

In the case of vehicles with ASC+T or DSC, the system must be deactivated with the switch. The ASC+T or DSC telltale and warning light must light up in the instrument cluster!

The brakes must be at normal operating temperature. For this purpose, gently warm up the brake disks/drums while dry by braking the vehicle several times.

E65 and E66: Carry out parking brake function check.

IMPORTANT: You should only use brake dynamometers whose test speed is less than equal to 5 km/h. You must follow without fail the guidelines contained in the operating instructions of the relevant test stand manufacturer. Failure to do so may result in damage to the vehicle and the system and also personal injury.
