Description

Overview

Brake Drum 16.5×7 11in PCD suits common trailer hubs that run 16.5in x 7in foundation brakes. Because drums see heat and load, matching PCD, pilot and height helps the shoes run true and reduces uneven wear.

• 16.5in x 7in braking surface size to match standard shoes
• 9.44in (239.8mm) drum pilot to locate on the hub
• 8.25in (209.5mm) drum height for correct stack-up

Compliance and Safety

Brake work affects road safety, so follow the axle or brake maker’s service limits and replace drums with cracks, damaged stud holes, or severe heat checking.

• Torque wheel nuts evenly and recheck after bedding-in
• Keep friction surfaces clean and dry during assembly
• Inspect shoes, rollers, cams and slack adjustment together
• Use suitable lifting gear because drums are heavy
