This listing is for a single replacement trailer brake drum hub, ideal for replacing worn, damaged, or corroded brake drums. It is suitable for axles with Knott Brake Systems using 203x40 brake shoes and will only replace brake drums with a casting reference of 7717, which is normally engraved into the rear side of the brake drum. This drum features a 4 stud wheel fitment with a 139.7mm PCD and requires a standard 50mm hub cap. It is suitable for use with M12 wheel bolts and has a 203mm drum diameter (internal size, 240mm overall diameter). To identify brake drums, match the casting numbers, which are normally inside the drum or on the outer edge. Ensure the new part is the same as the old one before fitting, as brakes are a safety system.
