A1 Cardone 1B-1000 Air Brake Disc Brake Caliper
for 2008 (please select make/model)

ADB calipers generate much shorter stops under the same loads and speeds when compared to drum brakes. ADB calipers enhance braking capability and increase safety. The brake pads may last twice as long as drum linings in most cases. ADB calipers also have a sealed design with an integrated automatic brake adjuster for optimal performance. This design also allows for easy access to the brake pads for a significantly quicker installation.

There are two ADB caliper designs. The first type is a sliding caliper with an integral brake actuator. This consists of a brake actuator that moves an eccentrically supported lever which transmits the force to the brake pads through a bridge with a threaded spindle on the end of the piston. The second type is a floating caliper. This design consists of a main body which includes the actuating and adjustment mechanisms and a brake carrier which enables the caliper to slide while holding the brake pads and transferring the load that is exerted during brake application to the axle.

Most manufacturers recommend a visual brake pad wear inspection every three months or 20,000 miles. A more thorough inspection is recommended at six months or 50,000 miles. Refer to the service intervals stated by the caliper original equipment manufacturer.

Most rotor manufacturers state that small radial cracks, no more than 1.5 mm wide and 1 mm deep are acceptable provided the cracks don't extend across more than 75 percent of the disc face. A rotor with cracks that extend to either edge of the rotor should be replaced. Grooves are acceptable as long as the groove is no deeper than 1.5 mm. Refer to the rotor manufacturer for exact specifications.

For most applications there is no need to remove the wheels. Inspection can be done by checking the wear indicators on the brake caliper with a flashlight.
