BMW 135i Brake Calipers

The factory-installed brake calipers on your BMW 135i are critical components of its braking system. As a matter of fact, without them, you wouldn't be able to brake at all. They're an essential part of the car's disc brake system.

How Your Brake Calipers Work

For you, braking is simple. You press the sole of your foot against the brake pedal, and your BMW 135i slows or comes to a full stop. There's a lot more to it than that, though. When you apply pressure to the brake pedal, that signals the master brake cylinder to send fluid to the calipers. The force of that fluid makes your brake calipers close onto the brake rotors, creating the resistance required to slow the rotation of the wheels. Since the calipers and rotors are both made of metal, the calipers are protected by brake pads to help prevent warping and scraping.

Signs of Brake Caliper Problems

Even the best brake calipers can go bad, due to the incredible heat and pressure generated during the act of braking. Here are some indications that yours may need to be replaced:

• You hear squealing or grinding noises when you apply the brakes
• The brake pedal feels soft or squishy
You have to repeatedly pump the brake pedal to get your brakes to work
• Your car pulls to one side when you brake

It's not advisable to drive for long when your calipers start to fail. Replacing them with genuine BMW brake calipers is the right way to go, since they're guaranteed to fit and perform properly right out of the box.
