Calipers are part of a vehicle’s disc brake system and are critical in stopping the car.
The caliper mounts on the brake rotor like a clamp. It houses the brake pads and pistons, slowing a car by creating friction with the brake rotors. When you step on your brake pedal, it transfers pressure to the pistons inside the caliper, pushing the brake pads against the rotor. This causes the vehicle to slow down and, eventually, stop.
Like other braking system parts, the calipers will wear down with time and use. The heat generated by the pads squeezing the rotor can weaken the seals inside the caliper. They typically don’t wear down as quickly as other braking components. Calipers can become rusty or dirty if a vehicle sits for an extended period, possibly leading the caliper to leak brake fluid.
If your brakes squeal, squeak, or grind, have them examined. If the pedal is soft or you see brake fluid on your wheels, have them inspected. Replacing the brake calipers usually starts at about $300 and can get into four figures, depending on the hourly labor rate.
