Description

Overview

Caliper adjuster mechanism spline type assembly keeps Knorr style air disc brake pad clearance within the correct working range. Additionally, it supports common trailer disc brake calipers and helps restore consistent operation after service work.

Features

This caliper adjuster mechanism spline type uses a splined drive to move the adjuster shaft and backplate cleanly. Additionally, the sealed housing protects the internal threads and springs from road spray, dust and corrosion. As a result, the mechanism helps maintain stable pad wear across the full service life.

Specifications and Materials

Part number: FB2831.
Firstly, this caliper adjuster mechanism spline type suits Knorr air disc brake calipers used on heavy trailers. It is designed for workshop replacement during caliper overhaul. Materials typically include hardened steel for the spline and adjuster components plus treated housings for durability.

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. SK 6/7 series, SN 6/7 series, SL 7, SM 7.

Compliance and Safety

When you replace a caliper adjuster mechanism spline type assembly, you support correct brake balance across the axle group. This helps keep stopping distances within design limits. Always follow the vehicle manufacturer brake service procedure and torque settings. In addition, carry out leak checks, running clearance checks and road tests before the trailer returns to service.

Trailer Applications

In addition, fleets use this caliper adjuster mechanism spline type on trailers that run Knorr air disc brake calipers in highway and regional haul work. It suits applications such as semi-trailers, B-double sets and PBS combinations where consistent brake performance is critical. Furthermore, routine replacement during brake overhauls can reduce call-backs and unplanned downtime.
