Get the Best Priced BMW 545i Master Cylinder

Your BMW 545i's master cylinder is the brake fluid reservoir that activates your hydraulic brakes when you step on your brake pedal. It's mounted on the engine. When you step on your brakes, you push a piston through the master cylinder, which, in turn, forces brake fluid through the brake lines. This fluid applies pressure to the caliper, which pushes the brake pads against the rotor. It's this action that stops your car. Automotive experts estimate that the typical driver applies the brakes at least 75,000 times a year. PartsGeek.com sells master cylinders for your BMW 545i.

Most master cylinder malfunctions involve leaks. When your master cylinder loses fluid, air gets trapped in the system, which will make your brakes feel spongy when you step down on them. Your brake pedal will go all the way down to the floor before your car finally stops.
