Automatic Cable Adjuster (ASZE Unit)
WARNING: This page is about a different car, the 2004 BMW Z4 and 2003 BMW Z4. However, it is still accessible from the selected car via links, so may be relevant.
The ASZE unit provides automatic cable adjustments (for normal stretch) and is located in the mounting pan. The ASZE unit consists of cable tensioning spring, rack extension, locking clip and hook. The ASZE unit holds both cables under equal tension via a balance arm. Parking brake lining wear is not compensated by the ASZE unit. Traditional adjustments at the wheels are still necessary.
