Understand How Your Brake Caliper Works

Brake calipers grip the brake rotor to slow down the wheel, using hydraulic pressure to squeeze the brake pads together. Caliper construction plays a crucial role in this process.

Most modern cars use floating calipers, which have one or two pistons that push the brake pad onto the rotor. Fixed calipers, on the other hand, have multiple pistons on both sides of the rotor. They provide better stopping power and heat dissipation, but are more expensive to manufacture.

Another important aspect to understand is the function of brake fluid. It’s the hydraulic fluid that transfers force from the brake pedal to the caliper, creating the pressure that clamps down on the rotor. Brake fluid needs to be changed periodically, as it absorbs moisture over time and loses its effectiveness. Low brake fluid level or leaks can cause the caliper to malfunction, making it harder to stop the car or causing the brake pedal to sink to the floor.

To recognize common signs of brake caliper issues, you need to have a basic understanding of how the caliper works. If you hear a grinding or squeaking noise when you apply the brakes, it could be a sign that the brake pads are worn out or the caliper is sticking.

Uneven brake pad wear can indicate a caliper that’s not functioning properly, causing one side of the rotor to wear out faster than the other. In some cases, a seized caliper can cause the car to pull to one side when you brake.

It’s important to address these issues promptly, as they can compromise your safety on the road.
