Description

Overview

Caliper slide pin and seal kit Wabco services PAN 19 and PAN 22 air disc brake calipers on heavy trailers. It renews the sliding pins and sealing points so the caliper moves freely and clamps the disc evenly. As a result, you improve pedal feel, reduce uneven pad wear and keep brake performance stable across the axle set.

Features

This caliper slide pin and seal kit Wabco supplies a matched set of pins, bushes, seals and hardware for one axle position. Firstly, it includes one short and one long guide pin so technicians can replace worn pins like for like. Additionally, Teflon bushes, dust excluder and gaiters protect the sliding surfaces from dirt and moisture. Moreover, steel caps, rings and the supplied grease complete the kit so workshops do not need loose parts from multiple sources. Finally, the matched contents help reduce comeback risk by keeping the caliper sliding system consistent with Wabco PAN series design.

Specifications and Materials

Part number: FB2874.

The kit contains one guide pin around Ø37.70 x 76mm and one guide pin around Ø38 x 118mm to match the original caliper layout. It also includes two M16 x 1.5 x 80mm and 120mm bolts for the pins, three Teflon bushes around Ø42 x Ø38 x 30mm, a bolt dust excluder and two guide pin gaiters. In addition, you receive two steel caps around Ø42.10mm in different depths, one plug, two rings around Ø44.5 x 1.25mm and a sachet of grease. These components support the guide pins, control movement and seal the sliding system when fitted and torqued to current Wabco instructions.

Compatibility and Fitment

This caliper slide pin and seal kit Wabco suits PAN 19 and PAN 22 air disc brake calipers used on heavy truck and trailer axles. It fits applications identified as 40 195.1 and 40 225.1 in many catalogues where the axle uses one short and one long guide pin. Before installation, measure the existing pins and bushes, then compare with Wabco and axle documentation to confirm the match. 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. 1628065, 3 434 3828 00, 85108166, 5001 866 626, 12 999 776, 6500700, CWSK.6, Pan 19, Pan 22, 40 195.1, 40 225.1

Compliance and Safety

Heavy vehicle foundation brake work directly affects stopping distance and stability, so only competent technicians should fit this kit. Always support the trailer safely, then follow the latest Wabco PAN service instructions during disassembly and reassembly. Additionally, inspect pads, discs, hoses and caliper mount faces at the same time so you do not leave worn parts in service. After refitting the caliper slide pin and seal kit Wabco, check for free caliper movement and verify torque on all fasteners. Finally, complete a controlled road test and confirm brake balance with suitable workshop equipment before the vehicle returns to duty.

Trailer Applications

Workshops use this caliper slide pin and seal kit Wabco on disc braked highway semi trailers, tankers, curtain siders and similar heavy combinations. It suits axles where PAN 19 or PAN 22 calipers sit on the trailer and need full pin and seal renewal. Regular replacement during brake relines helps keep the caliper square on the disc and reduces uneven pad wear. Consequently, fleets often see more predictable braking, fewer noise complaints and longer life from discs and pads when the sliding system stays in good condition.

Cross-reference and Suitability

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

Installers should still confirm caliper family, axle type and dimensions with current documentation before relying on any cross-reference during ordering or fitment.
