GM Brake Calipers

The factory brake calipers in your vehicle are an essential part of your braking system. In fact, it could be argued that they're one of the most important parts of a disc braking system. That's the type most modern GM vehicles have on their front brakes.

What Brake Calipers Do

Put simply, the brake caliper clamps down on the brake rotor to slow, and then stop, the wheel from turning. When you press on the brake pedal, brake fluid is sent out of the master cylinder. That fluid puts pressure the pistons inside the caliper, which forces the caliper against the rotor. Each caliper has brake pads inside to cushion the rotor from metal-on-metal contact that can warp it.

How to Know When Calipers Begin Failing

Even the highest-quality brake calipers can eventually start to fail due to the heat generated when you brake. Other than your warning light alerting, here are some signs to look for:

• Your brakes made grinding, squealing, or squeaking noises
• Your vehicle pulls to the side when you brake
• You have to pump your brake pedal to get your brakes to work
• Your brake pad feels soft or spongy

If you experience any of these signs, have your brakes looked at. Since the seals in your calipers can weaken and eventually break down, yours may have become dirty, contaminated, or rusty. You might even be leaking brake fluid. When you do need to replace your brake calipers, demand the best solution. That means installing the original GM brake calipers that are designed to fit and work with your model. You can find them online right here in our auto parts department.
