Meritor E1108 is an air brake spider assembly for 12.25 in. brakes, intended for Standard Forge axles that are not drilled for dust shields. It has a 5.63 in. pilot diameter and includes the E-759 bushing and E-1416 seal. When a spider is worn, cracked or out of alignment, you may see uneven braking, extra brake shoe wear or odd noises from the wheel end, so the camshaft and shoes are worth inspecting whenever it is replaced. This is a genuine Meritor part from Pro Gear and Transmission.
