Abstract
A drum brake for use in a brake system (10) having first (14) and second (16) shoes retained on a backing plate (20). The first brake shoe (14) has a first end (22) connected to an actuator (12) and a second end (26) connected to an anchor arrangement (24) and the second brake shoe (16) has a first end (36) connected to the actuator (12) and a second end (38) connected to the anchor arrangement (24) The actuator (12) responds to an input signal during a brake application by moving the first (14) and second (16) brake shoes into engagement with a drum (18). The anchor arrangement (24) includes a load sensor (64) for measuring a torque generated between the first (14) and second (16) brake shoes and the drum (18). The anchor arrangement (24) has a bracket (44) with a base (46) having first (48) and second (50) side walls which are secured to the backing plate (20). The first side wall (48) has a first central opening (56) therein while the second side wall (50) has a second central opening (58) therein. A core member (64) of the load sensor is retained by the bracket (44) between the first (48) and second (50) side walls is connected to a controller (28). First linkage (66) extends t…
