A disc brake is a wheel brake that slows rotation of the wheel by the friction caused by pushing brake pads against a brake disc with a set of calipers.

Disc Brake Caliper:

Brake Caliper failure is a very common problem to have. The Caliper can fail for many reasons. The piston can extend too far from excessive brake pad wear and the piston(s) can become stuck or the seals can tear. The calipers also can become “frozen” from overheating the brakes and they will no longer function properly. The seals can simply get old and dry and they will leak fluid. So as you can see, there are many reasons calipers can fail, so they require frequent inspection. They should be inspected every time the oil is changed in your engine.

The Caliper is the component of the braking system that actually puts pressure (friction) onto the rotors to make the vehicle stop. When you step on the brake pedal, the brake fluid is pushed through the brake lines and hoses, into the calipers and this pressure pushes the piston inside the caliper onto the brake pads. The pads then press against the rotors and stop the wheels from spinning. ...
... If the caliper goes bad, one of two things will happen. The vehicle will not stop properly or, the rotors may “lock” the wheel and make the vehicle feel like it is has no power.

Different Brands for OEM or Remanufactured Calipers:

If you find yourself in need of a replacement brake caliper, you can purchase either a remanufactured or new one. There are many companies that offer new calipers. Centric, AC/Delco, Motorcraft, Bendix, TRW as well as many others offer new calipers. A1 Cardone, ARC and AC/Delco all offer remanufactured brake calipers. The difference between new or remanufactured brake calipers is really just whether or not the non-wearing parts were ever used before. Both new and remanufactured brake calipers will always have new seals and sliding parts where necessary. The re-used outer casting and piston(s) is where you save money.

How Static and Floating Caliper Differs in Working Principle:

There are two distinct types of calipers that your vehicle can have. One type is called static or solid mount caliper, and the other is called a floating mount caliper. Solid mount calipers are mounted to brackets in a fixed position at the wheel. There are either two or four pistons in these calipers. In either case, the pistons are positioned on either side of the rotor. When the brake pedal is pressed, the pistons push the brake pads evenly against the rotor from both sides. With this design, the rotors and pads wear evenly and the vehicle handles better under hard braking conditions.

Floating calipers are mounted onto a bracket at the wheel with a sliding bolt design. These calipers normally only have a single piston that puts pressure on the pads. When the piston presses the outer pad, it presses the pad against the rotor and the force slides the whole caliper away from the rotor and pulls the inside pad against the rotor. This causes uneven wearing of the pads, as the piston side pad will wear more than the opposite side pad. With this design, the outer pad will almost always wear faster.
