  • Patent number: 9303703
    Abstract: An improved bracket assembly for receiving a brake assembly and a brake actuator is provided. The bracket assembly includes a tube configured to receive a camshaft of the brake assembly and an actuator mounting bracket disposed proximate a first end of the tube. The actuator mounting bracket is configured for coupling to the actuator and defines an aperture configured to receive the tube. The bracket assembly further includes a brake spider mounting bracket disposed proximate a second end of the tube. The spider mounting bracket includes a body defining inboard and outboard sides, is configured to receive a brake spider on the outboard side and defines an aperture configured to allow the tube to extend therethrough. The spider mounting bracket further includes a neck extending from the inboard side of the body that is configured to receive the tube and positions the weld away from the body to reduce stress.
