This replacement set is designed for trailer technicians and owners who need to maintain the braking performance of their Ifor Williams trailers equipped with Knott brake systems. It provides a comprehensive solution for replacing worn components, including pre-fitted bearings, axle nuts, and hub caps, ensuring reliable stopping power for twin-axle trailers up to 2700kg. A critical caveat is that these parts are strictly for Knott systems on trailers manufactured from 1996 onwards, and they are not compatible with older configurations or non-Knott brake setups.

Yes, these are compatible with select single and tri-axle models as long as they feature the Knott 200 x 50mm brake system.
Yes, the bearings are sealed-for-life units and come pre-fitted into the drums, so no additional greasing is required.
No, this kit includes the necessary one-shot axle nuts as part of the package.
No, these parts are not suitable for trailers manufactured prior to 1996.
These drums feature a 6.5-inch Pitch Circle Diameter (PCD) designed for 5-stud wheels.
Verify the trailer was manufactured in or after 1996 and confirms the axle is a Knott system; check for debris or burrs on the axle shaft.
Ensure the brake shoes have been correctly backed off and adjusted to the proper clearance after the drums have been seated.
Before purchase, verify that your existing brake shoes measure 200 x 50mm and that your hub is a 5-stud design with a 6.5" PCD. These parts are unsuitable for trailers built before 1996 and will not fit non-Knott brake systems. During installation, always use a new one-shot axle nut, as these are designed to be torqued to a specific specification and must not be reused once removed. Regularly inspect the dust caps and ensure the brake shoe adjustment is correctly set to maintain optimal performance after the initial break-in period.
