What is brake caliper?
A caliper is part of the disc brake system, the type most cars have in their front brakes. The car brake caliper houses your car’s brake pads and pistons. Its job is to slow the car's wheels by creating friction with the brake rotors. The brake caliper fits like a clamp on a wheel's rotor to stop the wheel from turning when you step on the brakes. Inside each caliper is a pair of metal plates known as brake pads. When you push the brake pedal, brake fluid creates pressure on pistons in the aftermarket brake calipers, forcing the pads against the brake rotor and slowing your car.
The symbol of your brake caliper is broken
1.1. Pulling to one side
A seized brake caliper or caliper sliders can cause the vehicle to pull to one side or the other while braking. Sometimes the car will pull while driving down the road as well.
1.2. Fluid leaks
Brake calipers, which are activated by hydraulic fluid, can develop brake fluid leaks from the piston seal or bleeder screw.
1.3. Spongy or soft brake pedal
A caliper that is leaking can cause a spongy or soft brake pedal. Also, a seized piston or sticking sliders can create excessive clearance between the pad and rotor, causing abnormal pedal feel.
1.4. Reduced braking ability
Obviously, if you’ve got a faulty caliper, resulting in a soft brake pedal, your car will exhibit reduced braking ability.
1.5. Uneven brake pad wear
Uneven brake pad wear is often caused by sticking caliper slider pins. In some cases, a sticking caliper piston can also cause uneven wear. The reason being, in both scenarios, the pads will be partially applied, causing them to drag across the rotor.
1.6. Dragging sensation
Obviously, if you’ve got a faulty caliper, resulting in a soft brake pedal, your car will exhibit reduced braking ability.
A stuck brake caliper can cause the pads to be pressed against the rotor while driving. As a result, the car may exhibit a dragging sensation, since the brakes at the affected wheel are applied (or partially applied) at all times.
1.7. Abnormal noise
Eventually, a sticking brake caliper will wear down the brake pads. And when that happens, you’ll hear the familiar sound of grinding brakes.
How to install the brake calipers
After you taking off the wheel that’s in front of the brake caliper you’re replacing, you remove the 2 bolts on the back of the caliper with a ratchet, then you pry the caliper off of the brake pads with a screwdriver and remove the brake pads from the caliper bracket. Last , you take out the 2 bolts holding the caliper bracket in place.
