Description

Overview

The brake shoe anchor pin circlip secures the anchor pin in heavy vehicle drum brake foundations, so the brakes keep their designed geometry under load. This brake shoe anchor pin circlip suits typical 30mm anchor pin hardware and provides a compact way to retain the pin without bulky fasteners. As a result, it helps fleets maintain consistent brake performance while keeping service work straightforward.

Features

This circlip locates in a machined groove on the anchor pin and holds position under repeated braking cycles. Its 30mm internal diameter suits common heavy trailer and truck anchor pin sizes, while the 1.5mm section thickness provides retention without taking up space in tight brake spider castings. Technicians can remove and refit the circlip with standard retaining ring pliers during routine brake relines.

• Designed to retain brake shoe anchor pins in heavy vehicle drum brakes
• 30mm internal diameter with 1.5mm section thickness for common pin sizes
• Compact profile to clear brake shoes, rollers and return springs
• Reusable design when inspection shows no distortion or cracking

Specifications and Materials

Part number: FB3205.
This brake shoe anchor pin circlip has an internal diameter of 30mm and a nominal thickness of 1.5mm, which suits many heavy trailer and truck anchor pin arrangements. The general purpose sizing also makes it suitable for a wide range of brake shoe and anchor pin combinations where a 30mm shaft size applies. The circlip is typically manufactured from spring steel heat treated for elastic deflection and retention force, however the exact grade may vary between production batches.

Compatibility and Fitment

This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. 1229X1116, 214108, 31624, 34-1525, 820006, BP3205, E-801, FL34.1525, WT3205, 17-618, E-4891, 28-1252, E-2380
When installing the brake shoe anchor pin circlip, clean the groove and inspect the anchor pin for wear before refitting. Confirm the ring seats fully in the groove and that the open ends do not foul shoes, rollers or cam hardware through the full travel of the brake. If any interference appears, correct it before returning the vehicle to service.

Compliance and Safety

Correct retention of the brake shoe anchor pin supports overall compliance with heavy vehicle brake performance requirements. Follow the vehicle or axle manufacturer’s brake service instructions when fitting this brake shoe anchor pin circlip. Depressurise the air system, chock wheels and support the axle securely before removing brake components. Replace any distorted, cracked or heavily corroded circlips instead of reusing them, then complete a functional brake check after reassembly to confirm components move freely without binding on the circlip.

Trailer Applications

This brake shoe anchor pin circlip suits heavy trailer and truck drum brake assemblies that use a 30mm anchor pin retained by an external circlip. Common applications include highway semi-trailers, dog trailers and similar heavy combinations where cam-operated S-cam brakes are fitted. Fleets can also keep these circlips on hand as service stock for mixed-age equipment, because the general purpose sizing and cross-reference set covers multiple OEM references. However, compare the circlip dimensions and groove engagement against the removed part before using it on any particular axle.

Cross-reference and Suitability

This part cross-references to or suits the following equivalent part numbers and compatible alternatives:

Additionally, fleet maintenance teams can use this cross-reference set to align internal stock codes with OEM and aftermarket references while still consolidating to a single service circlip where dimensions match.
