Abstract

A disc brake assembly includes a brake pad having a first pad abutment spaced from a second pad abutment and a third pad abutment positioned between the first pad abutment and the second pad abutment. An actuator is operable to apply a force to the brake pad to apply the brake. The disc brake assembly has a first reaction abutment facing the first pad abutment, a second reaction abutment facing the second pad abutment, and a third reaction abutment facing the third pad abutment. The first, second and third pad abutments are operable to transfer brake pad drag torque to the first, second and third reaction abutments respectively. The disc brake is configured such that under no load conditions with the third pad abutment engaging the third reaction abutment, the first pad abutment is spaced from the first reaction abutment.
