The video shows how easy it is to replace the front and rear brake pads and rotors, without paying a shop a few hundred dollars. Since the video was published, BMW has introduced electric parking brake systems on many of the newer and current models. While the front brake renewal procedures have not changed, the procedures for replacing the rear pads is unique, due to the addition of the electric parking brake system. There are currently two different electric parking brake systems. The first generation system uses an electrical actuator that activates cables to standard drum-style parking brake assemblies. The second generation system uses electric actuators directly on the brake calipers. Here are the links to our other brake service videos: http://blog.bavauto.com/10012/bmw-brake-pad-and-rotor-change-brake-job-diy-video/ http://blog.bavauto.com/11430/bmw-diy-late-model-brake-pad-and-rotor-how-to-%E2%80%93-e90-e92-e60-e65-e66-e89-z4-etc/ As noted above, the second generation electric parking brake system incorporates an electric motor driven caliper piston extender mechanism than mechanically extends the brake caliper piston to compress the pads against the brake rotor (as opposed to a separate small cable actuated drum brake assembly inside the brake rotor’s hub, or hat). Unlike a standard brake caliper, the piston cannot be simply pushed back into the caliper, using a piston compressor tool. According to BMW, the pistons must be retracted through use of the BMW factory scan/diagnostic tool. The tool is connected to the vehicle’s diagnostic port and then programmed to retract the pistons through the parking brake motor actuators. Once the parking brake piston extenders are retracted, the s
