Description
Overview:
The Genuine Knott Avonride Half Shells are replacement brake components used inside Knott drum brake assemblies to provide a smooth, accurate bearing surface for the brake actuator. Supplied as a matched set of two pieces, they are built from robust metal for long service life under towing and site conditions. This OEM set (MPN 572000) is engineered for a precise fit in Knott brake models 200 and 203, and is also specified for certain 250 applications. Suitable for trailers fitted with Knott Avonride running gear-such as utility, plant, boat, agricultural and caravan trailers-the half shells help restore consistent braking performance, reduce uneven wear, and support reliable operation during routine servicing or brake overhauls.
