ATE BMW Brake Master Cylinders for BMW 1 Series E82 (2008-2013)

Clear BMW chassis

Please ensure your correct model is selected

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.

Make sure your pedal force is actually making it to the calipers, otherwise, you won't be able to stop. Stop quicker, better, and more reliably with new braking components.
