Description

Overview

Caliper tappet cover with bolts works as a direct service component for BPW TSB 3709 and 4309 disc brake calipers on heavy trailer axles. It closes the tappet and adjuster area so road grime and moisture stay out. As a result, the caliper can clamp more consistently during normal use and after an overhaul.

Features

• Cover set supplied complete with matching bolts for straightforward replacement during caliper service
• Suits BPW TSB 3709 and 4309 disc brake calipers on heavy transport trailer axles
• Helps shield the internal tappet and adjuster mechanism from contamination
• Works with approved BPW repair procedures for consistent disc brake performance

Specifications and Materials

This caliper tappet cover with bolts fits BPW TSB 3709 and 4309 disc brake calipers commonly used on modern trailer axles. The set normally includes the main cover, a matching mechanism seal and the required mounting bolts, so you can refit the assembly in one controlled operation.

Part number: FB2702.

Use the supplied bolts in the original locations and tighten them to the torque figures listed in the relevant BPW workshop literature for the axle and caliper. Material and finish follow typical BPW-style caliper service parts and suit heavy transport braking environments.

Compatibility and Fitment

This caliper tappet cover with bolts suits BPW TSB 3709 and BPW TSB 4309 disc brake calipers used on trailer axles. Always confirm the caliper type from the axle identification plate or an approved BPW parts catalogue before ordering, then match the existing cover layout and bolt pattern during installation. 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. 05.010.95.31.0, 0501095310

Compliance and Safety

Brake work must always follow the BPW service procedures for the specific axle and caliper combination. After you fit the caliper tappet cover with bolts, check tappet adjustment, pad seating and caliper slide movement so they remain within specification. Additionally, confirm there are no air leaks, fluid leaks or fouling between the cover, bolts and nearby suspension or hub hardware.

Once reassembled, carry out a functional brake test in a controlled area, then recheck all related fasteners after the vehicle completes an initial loaded run. Where required, ensure the vehicle continues to comply with ADR requirements and NHVR expectations for heavy vehicle brake performance.

Trailer Applications

This caliper tappet cover with bolts typically appears on BPW TSB 3709 and 4309 disc braked axles fitted to semi-trailers, curtain-siders, tippers and other on-road heavy trailers. It suits fleet brake maintenance programs where technicians renew several caliper components together during pad changes or full caliper overhaul.

During planning, inspect the existing cover and bolts for corrosion, thread damage or distortion. If the cover no longer seals cleanly or the bolt heads show wear, replacing the cover and bolts as a matched set helps maintain stable brake performance over the full pad life.
