BMW Brake Master Cylinders for BMW 1 Series

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.

When the brake master cylinder goes bad, your brakes will no longer operate as they should. You might get a brake warning light on your dashboard and the brake pedal might sink down and not return to its normal position. When this occurs, be sure to replace that master cylinder. The brake master cylinder is bolted to the Brake Booster with two bolts.

The brake booster in a car is essential for improving the efficiency of the braking system by amplifying the force exerted on the brake pedal. As time passes, the brake booster may undergo wear and tear, resulting in problems like reduced braking power, a soft or spongy brake pedal sensation, and potential brake fluid leaks. These issues pose a threat to the overall safety and performance of the vehicle. Consequently, replacing a worn or malfunctioning brake booster is crucial to maintaining optimal braking performance and ensuring the safety of the vehicle.
