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.

One of the common problems on these BMW’s, these bushings will tear/rip over time. You might feel a shimmy or vibration in the front when you brake. Inspect your bushings!
