Front Brake Caliper Replacement
Disc brakes are commonly used on each wheel of a modern car’s braking system. Brake calipers are part of a disc brake system.
Brake pads are located in the brake caliper. When the brake master cylinder applies pressure to the brake caliper, it distributes pressure to the brake pads. The brake pads come into contact with the brake rotor (disc). The more pressure generated in the brake caliper, the more pressure is applied to the brake pads. The greater the pressure applied to the brake pads, the sooner a vehicle stops.
Brake calipers operate in much the same way as do brakes on a bicycle. Instead of mechanically pulling a cable to get rubber blocks to come in contact with the rim of the bicycle tire, hydraulic pressure pushes brake pads into contact with a brake rotor (disc).
To replace a brake caliper, the technician first removes the wheel, then the defective caliper. We recommend replacing brake calipers as a pair to maintain optimum operating efficiency. After replacing the brake caliper, air must be removed from the brake system to enable it to function correctly.
