Shell disc brake

摘要

A disc brake with a caliper housing having first and second side walls, the first wall having a cavity with a piston slidably mounted therein, the piston having a first shoe for frictional engagement with one of the sides of a rotor, the housing also having a bridge spanning the sides of the rotor and extending from the bridge, the housing having a second wall with an attached second shoe for frictional engagement with the rotor opposite the first shoe. A bracket is connected with the vehicle having first leading and second trailing reaction arms. The caliper is slidably mounted with the bracket arms. Extending the piston from the caliper housing to actuate the brake brings the shoes into engagement with the rotor and causes the inboard shoe to react on the trailing bracket arm and the caliper housing to react in the trailing direction into the leading bracket arm.
