E39 Brake Booster Brake Fluid Leak

Posted in San Diego BMW Auto Repair Service by San Diego BMW Auto Repair Service on May 16, 2013

This is a Brake Booster & Master Cylinder out of a E39 530.  This master cylinder had been leaking brake fluid for a while. The brake fluid leaked into the brake booster, causing the booster to start to rust on the inside.  Symptoms of a leaking master cylinder are a very soft brake pedal, that travels to the floor.  A brake booster going bad can cause a very stiff brake pedal.  This vehicle had a strange combination of both.

We recently started performing Carbon or Walnut Blasting.  This is a process used on Direct Injected vehicles to clean the carbon build up off of the intake valves.  Carbon build up can lead to rough idle, misfire and poor performance issues.  This customer commented that his vehicle felt as it did when it was brand new.  ImageImageImage
