Brake shoe expander for KNOTT brake drum 200x30–250x50mm

Brake shoe expander for KNOTT brake drum 200x30–250x50mm

The KNOTT replacement brake shoe expander for 200x30–250x50 mm drums is a durable working component of the braking system responsible for expanding the brake shoes inside the drum. It ensures reliable force transfer from the brake mechanism, stable brake shoe operation, and even pressure on the drum surface – resulting in effective, repeatable braking.

This part is designed for KNOTT brake drums with dimensions ranging from 200x30 mm to 250x50 mm . It is used on KNOTT 1350, 1500, and 1800 kg axles in trailers and semi-trailers. Suitable as a replacement part for KNOTT brake system service.

Replacing a worn brake caliper restores proper brake shoe geometry and stroke , reduces uneven brake lining wear, and shortens the brake response. We recommend replacing pairs on one axle, along with inspecting the condition of the brake shoes, springs, and drums. This simple service procedure significantly improves the safety and reliability of the trailer's braking system.
