Description

Overview

Caliper boot and bush repair seals restore protection and guidance for BPW TSB 3709 and TSB 4309 disc brake calipers on heavy trailer axles. These kits help keep the sliding system clean, supported and moving freely, so braking performance stays consistent under load.

Because the kit targets boots and bushes only, it suits workshops that already have pins and hardware but still need to address wear in the guiding and sealing components. As a result, it offers a focused service option for routine caliper maintenance.

Features

• Boot and bush components sized to suit BPW TSB 3709 and TSB 4309 disc brake calipers for common trailer applications.
• Supports smooth caliper sliding, which helps maintain even pad contact and reliable braking response.
• Helps keep contaminants away from moving parts, so service intervals can be more predictable.
• Compact kit format that fits easily into standard brake overhaul workflows in busy workshops.

Specifications and Materials

This caliper boot and bush repair seals kit is intended for BPW TSB series disc brakes used on heavy trailers. It focuses on the guiding and sealing elements around the caliper sliding system, so you can combine it with existing hardware or pad kits as required.

Part number: FB2794.

Compatibility and Fitment

Caliper boot and bush repair seals in this kit are sized for BPW TSB 3709 and TSB 4309 disc brake calipers commonly found on European-style trailer axles. In addition, the focused component mix makes it suitable for both scheduled overhauls and corrective repairs after contamination or wear.

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. TSB 3709, TSB 4309.

Compliance and Safety

When you fit caliper boot and bush repair seals, always follow current BPW service instructions and torque specifications, because improper assembly can affect braking performance. Additionally, use appropriate cleaning agents and avoid damaging sealing surfaces during disassembly and installation.

After installation, you should confirm free caliper movement and check for air or fluid leaks where applicable. Finally, road test the trailer in a controlled environment to verify braking behaviour before returning it to regular service.

Trailer Applications

These caliper boot and bush repair seals suit BPW TSB 3709 and TSB 4309 disc brake calipers used on many highway semi-trailers, B-double sets and specialised freight trailers. They are particularly relevant where consistent braking and low downtime are priorities.

Workshops can use this kit during pad changes or full brake overhauls on compatible BPW-equipped trailers, which helps maintain reliable braking performance over long distance haulage routes.
