BMW Brake Master Cylinders for BMW Z3 (1996-2002)

The brake master cylinder is responsible for distributing fluid from the reservoir to the front and rear brake systems. The fluid reservoir actually sits on top of the master cylinder with hard metal brake lines running out of it. There are a few places where the master cylinder can leak and cause a spongy or soft brake pedal. The inside has several pistons with o-rings and seals that can fail and allow brake fluid to escape. Likewise, the external metal lines also have o-rings where fluid can seep out or let air/moisture in.

Has your brake pedal become stiff and hard to depress, or goes right to the floor with no pressure or feel, most likely the brake booster unit has failed. Replace the brake booster right away to restore proper braking performance.
