The Meritor Air Brake Spider forms the foundation mounting structure for drum brake hardware at the axle end. This spider assembly uses a 7.25-inch bolt circle and 5.50-inch pilot diameter, giving the brake setup defined mounting details for proper placement. It holds the anchor, cam, shoe, and related mechanical brake areas in position as air brake force moves into the foundation assembly. The spider’s role stays structural, while air pressure control happens through separate valves, chambers, and lines. The Meritor A3211J5782 places the brake hardware around a measured axle-end mounting base.
