Meritor 53-123601-002 or 53123601002 is an X30 lightweight balanced brake drum measuring 15.00 in. by 8.63 in., with outboard drum mounting for disc wheels. Ten bolt holes of .94 in. diameter sit on an 11.25 in. bolt circle, with an 8.78 in. pilot diameter, and the brake surface is 9.11 in. wide.
The drum is the rotating friction surface the brake shoes press against to slow the truck. A worn drum can show cracks running through the wall, deep scoring where the lining has worn away, or an out-of-round surface that wears one side of the lining faster. This is a genuine Meritor part from Pro Gear and Transmission. Call us to confirm proper fit for your axle.
