IMPORTANT INFORMATION

Always confirm the correct OEM part number, wheel brake type, and brake dimensions before ordering, as Knott produces several brake shoe configurations including 160×35, 203×40, 200×50, 250×40, and 300×60 variants that are not interchangeable. When replacing brake shoes, it is recommended to inspect the brake drums, adjusters, springs, cables, and wheel bearings for wear to ensure optimum braking performance and long-term reliability. Community maintenance discussions also commonly advise measuring the drum diameter and shoe width rather than relying solely on trailer model, as different production years may be fitted with different Knott axle specifications.
