Description

Overview

Caliper adjuster mechanism retainer kit Wabco Pan 17 19 22 keeps the adjuster hardware seated in Wabco Pan 17, Pan 19 and Pan 22 air disc brake calipers on heavy trailers. This stable seating helps maintain consistent pad clearance and reliable braking performance in demanding freight work. As a result, the kit supports predictable brake response over regular service intervals.

Features of this caliper adjuster mechanism retainer kit

This kit combines the critical washers, spring and circlip in one matched set for Wabco Pan 17, Pan 19 and Pan 22 calipers. Workshops can replace worn adjuster hardware in a single step instead of chasing individual pieces. Additionally, matching parts help maintain correct preload on the adjuster mechanism, which supports smooth operation during automatic adjustment. Technicians can therefore reduce setup time while keeping hardware consistent across multiple axles.

Specifications and Materials

Part number: FB2906.
The kit includes a 41.4 × 14.25 mm washer, a 22.30 × 22.15 mm coil spring and a spring washer. It also carries 49.4 × 35.5 mm and 45 × 32 mm washers plus a circlip so the adjuster mechanism stays supported under load. Components use suitable steel grades for air disc brake hardware to handle clamping forces, road spray and temperature changes in heavy vehicle service.

Compatibility and Fitment

This kit suits Wabco Pan 17, Pan 19 and Pan 22 air disc brake calipers commonly fitted to European style trailer axles. Firstly, technicians should compare the removed washers, spring and circlip with the kit contents during disassembly. Then they can install the new components in the same order, using the correct seating faces and orientation. Finally, they should follow the relevant Wabco instructions for adjustment and calibration so the mechanism runs freely.

Compliance and Safety

Correct adjuster retention supports stable brake performance, so only competent personnel should carry out this work. Always chock wheels, isolate air supply where required and follow workshop lock out procedures before removing any caliper components. After refitting the adjuster hardware, technicians must check caliper slide movement and confirm pad clearance. They should also perform a brake function test and leak check before the trailer returns to service.

Trailer applications for Wabco Pan adjuster retainer kit

Wabco Pan 17, Pan 19 and Pan 22 air disc brake calipers appear on many highway freight, tanker and refrigerated trailers. By keeping a caliper adjuster mechanism retainer kit on hand, fleets that run these calipers can reduce downtime during planned overhauls and unplanned repairs. In addition, stocking these kits alongside pads, slide pin sets and calibration bolts simplifies brake maintenance across mixed fleets.

Cross-reference and Suitability

No additional cross reference numbers currently appear in manufacturer documentation for this adjuster retainer kit. Selection should therefore follow the stated Wabco Pan 17, Pan 19 and Pan 22 applications and the visual match between removed hardware and kit contents.
