Description

Overview

The brake shoe spring retainer pin 70mm secures brake shoe return springs on the backing plate. It helps keep the shoes correctly located during normal trailer and truck operation. This keeps foundation brake hardware stable and can make future servicing easier.

Features

This general usage pin uses a 70mm overall length that suits many standard drum brake layouts. The 7mm shank diameter aligns with common holes in shoes and backing plates so the pin seats firmly, and the formed head helps retain the spring under vibration. It also has a simple profile, so technicians can install or remove the pin quickly during routine relines.

Specifications and Materials

Brake shoe spring retainer pin 70mm provides a nominal 70mm overall length. The shank diameter measures approximately 7mm based on the supplied dimensions. These values match many standard foundation brake designs on truck and trailer axles, and they suit applications that specify a general purpose retainer pin.

Compatibility and Fitment

Brake shoe spring retainer pin 70mm suits drum brake assemblies that call for a 70mm pin with a 7mm diameter. It targets common heavy vehicle axles that use conventional foundation brake hardware rather than proprietary pin kits. Always compare the removed pin against the replacement, then check the seating depth and confirm the required dimensions with the axle or brake manufacturer before final installation.

Compliance and Safety

Correctly fitted brake shoe spring retainer pins help maintain spring tension and shoe position, which supports stable braking response and even lining wear. Inspect backing plate holes, return springs and retainers whenever you replace this pin. Follow your workshop safety procedures, support the vehicle securely, and release stored air pressure from pneumatic systems before starting any brake work.

Trailer Applications

Workshops can use brake shoe spring retainer pin 70mm in mixed fleets because many trailers and rigid trucks share similar drum brake layouts. It suits routine brake relines, scheduled maintenance and defect repairs where a straightforward general purpose pin provides an effective replacement. Keeping standardised pins on hand can also help reduce downtime once fitment is confirmed.

Cross-reference and Suitability

No one has formally documented specific cross-reference part numbers for this brake shoe spring retainer pin yet. Treat it as a general usage option and verify suitability against OEM or axle manufacturer information whenever you replace an existing retainer pin.
