Spring applied brake and drive axle assembly

摘要

A brake assembly includes a piston housing (34), a piston (32) moveably arranged within the piston housing, and a bearing cover (38) mounted to the piston housing. A spring assembly (35) is located between the piston and the bearing cover, wherein mounting the bearing cover to the piston housing compresses the spring assembly to achieve an initial spring force. The initial spring force of the spring assembly causes the piston to act against a vehicle brake disc assembly (25) when mounted to a vehicle axle that passes through the spring assembly.
