Description

Overview

This brake shoe anchor pin bush BPW suits BPW open end brake shoes on heavy trailer axles. It provides a stable bearing surface for the anchor pin under repeated braking loads, which helps keep brake shoe alignment consistent. As a result, lining contact can stay more even and wear across the drum and linings is more uniform. It also suits workshop replacement where reliability and interchangeability matter.

Features

This brake shoe anchor pin bush BPW uses a proven plain bush style with dimensions suited to BPW open end shoe applications. The 60mm length supports the anchor pin across a wide contact area, while the 36mm internal diameter and 40mm outside diameter provide a snug fit in the shoe and backing component. Where BPW maintenance instructions specify it, the plain bush style also supports regular greasing practice. In turn, replacing a worn bush can help restore correct brake shoe support.

• 60mm long bush to support the anchor pin across the full shoe width
• 36mm internal diameter with 40mm outside diameter for BPW open end shoes
• Plain bush design suited to heavy trailer brake service conditions
• Replacement option for workshops maintaining BPW foundation brakes

Specifications and Materials

This brake shoe anchor pin bush BPW is configured around a 60mm bush length for BPW open end shoes, which helps the brake shoe stay properly located on the anchor pin during service. The internal diameter is 36mm and the outside diameter is 40mm, so the bush fits typical BPW new generation anchor pin hardware while still allowing free rotation when correctly lubricated. Material selection and wall thickness are intended for high contact pressures seen in heavy trailer brakes, while regular inspection and greasing support long service life. Part number: FB3217.

Compliance and Safety

In heavy vehicle braking systems, the brake shoe anchor pin bush is a safety critical support component. Inspect bushes for wear, fretting or ovality and replace them before excess movement develops at the shoe. Excess clearance at the anchor pin can contribute to uneven brake application, lining taper wear and noise, and it may also increase the risk of hardware damage under emergency braking. When replacing the bush, follow workshop procedures, torque settings and lubrication recommendations from BPW and relevant standards bodies, then confirm the brake operates smoothly before returning the trailer to service.

Trailer Applications

This brake shoe anchor pin bush BPW suits BPW open end shoes used on many new generation trailer axle sets. It commonly appears in drum brake assemblies on semitrailers, dog trailers and other heavy combinations where BPW axles are specified. It can also suit linehaul and regional applications where high mileage and frequent braking events place significant load on the brake hardware. When used alongside the correct BPW anchor pins, springs and shoes, it forms part of a complete foundation brake service kit that helps keep the trailer compliant and on the road.
