Abstract
A brake assembly includes a piston housing, a piston moveably arranged within the piston housing, and a bearing cover mounted to the piston housing. A spring assembly 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 when the brake assembly is mounted to a vehicle axle that passes through the spring assembly.
