Description

Overview

This boot bush 36mm supports the rubber boot around the brake cam area and helps protect the camshaft entry on heavy trailer axles. It suits SAF-style brake layouts where the boot seals against the spider and cam tube. In service, the boot bush 36mm helps keep dust, moisture and road grime away from the moving brake components.

Features

Firstly, the compact 17mm length keeps the boot seated without adding unnecessary stack height in the brake spider. Secondly, the 36mm internal diameter matches common SAF cam boot hardware so the bush locates accurately around the cam tube. Additionally, the 58mm outer diameter gives a snug fit in the spider housing to reduce movement in service. As a result, the boot bush 36mm helps maintain a reliable seal during repeated brake applications.

Specifications and Materials

Length approx. 17mm, internal diameter 36mm, outer diameter 58mm, based on established SAF brake bush sizing. Typically this rubber style bush sits between the spider bore and the flexible boot and supports the boot lip so it stays evenly loaded.

Compliance and Safety

A correctly fitted boot bush 36mm helps reduce contamination around the brake cam, which supports consistent brake response. In addition, technicians should inspect the camshaft, seals and boot during any brake relining or drum removal and replace worn bushes as required. Always follow workshop safety procedures, isolate the trailer, and chock wheels before beginning brake work. After installation, recheck clearances and confirm free cam movement before returning the trailer to service.

Trailer Applications

Workshops use this boot bush 36mm mainly during brake overhauls on SAF pattern trailer axles. It suits fleet maintenance where consistent sealing around the cam area reduces premature wear on cam supports and brake components. Furthermore, it is suitable for general freight, tanker and tipper trailers that operate on sealed or mixed road conditions and rely on regular brake servicing. For best results, replace bushes in axle sets so both sides of the trailer maintain similar support and sealing performance.
