Abstract:
1. A disc brake assembly for a vehicle, the vehicle having a primary direction of movement, the disc brake assembly including: 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 operable to apply a force to the brake pad to apply the disc brake assembly; 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 reaction abutment and third reaction abutment extending substantially parallel to the third reaction abutment; and said first, second and third pad abutments being operable to transfer brake pad drag torque to the first, second and third reaction abutments respectively, the disc brake assembly being 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, and wherein the disc brake assembly is configured such that applying the brake when the vehicle is traveling in the primary direction of movement, braking with a first force resulting in a first circumferential drag force on the brake pad is reacted substantially entirely at the third reaction abutment alone, and braking with a second force higher than the first force and resulting in a second circumferential drag force on the brake pad that is higher than the first circumferential drag force is reacted at both the third reaction abutment and the first reaction abutment.
