AIR DISC BRAKE SYSTEM WITH CALIPER RETRACTION AND METHODS FOR THE USE AND ASSEMBLY THEREOF

An air disc brake system includes a carrier and a guide pin mounted to the carrier. A caliper is slidably mounted on the guide pin. The caliper has an annular groove extending radially outwardly from an inner circumferential surface. The caliper is moveable relative to the guide pin from a non-braking position to a braking position. A friction ring is disposed in the annular groove and is deformable from a first configuration when the caliper is in the non-braking position to a second configuration when the caliper is in the braking position. The friction ring biases the caliper from the braking position to the non-braking position. Methods of using and assembling the air disc brake system are also provided.
