The disc brake system in your BMW car or SAV relies on a number of parts – including the brake calipers –working together to slow -- and eventually stop -- the wheels' rotation. For you, it's simple. You press your foot against the brake pedal. However, there's a lot more to the process.

How Brake Calipers Work

When you apply pressure to the brake pedal, the master brake cylinder directs hydraulic brake fluid to pistons inside the brake calipers. The pressure builds and forces the calipers to clamp onto the brake rotors. That produces the friction, or resistance, needed. Since the calipers and rotors are both made of metal, their contact is protected by brake pads that are attached to the calipers.

However, even the best brake components can begin to go bad due to the heat and pressure of the braking act. If your brake pads get too thin or fail, the caliper seals can begin to deteriorate. If that happens, the calipers can corrode. That makes it harder for you to stop on command.

How to Recognize Failing Brake Calipers

Signs that your brake calipers are going bad include:

You hear grinding or squealing sounds when you're braking
The brake pedal feels softer than usual when you press on it
Your Infiniti pulls to one side when you brake
The brake warning dash light comes on
