Description

Overview

Caliper metal rubber bush 32mm supports the sliding pins in Knorr SB and SN air disc brake calipers on heavy trailers. It helps the caliper move smoothly on its guides so pad contact stays even under braking. As a result, you maintain consistent braking response and reduce uneven wear across the axle group.

Features

• Firstly, short 32mm bush that supports a sliding guide pin in Knorr SB and SN air disc brake calipers.
• Additionally, metal outer shell with rubber inner sleeve helps control caliper movement and absorb vibration.
• Moreover, service replacement design allows technicians to restore caliper alignment during routine brake overhauls.
• Finally, suitable for heavy trailer applications where reliable and predictable braking performance matters every day.

Specifications and Materials

This caliper metal rubber bush 32mm sits in the caliper carrier or body around a sliding guide pin. The bush keeps the pin supported so the caliper can move freely when the pads apply against the disc. Construction normally uses a steel outer body with bonded rubber inside to control movement and isolate vibration from the carrier. Part number: FB2861.

Compatibility and Fitment

This bush suits Knorr SB and SN series air disc brake calipers on heavy trailers. These calipers use a short 32mm guide pin bush in the carrier to support the sliding mechanism. Before installation, measure the old bush and housing bore, then confirm match with current Knorr and axle documentation. In addition, check both sides of the caliper so the pair of bushes matches in length and condition.

Compliance and Safety

Heavy vehicle brake work affects stopping distance and stability, so only competent technicians should replace this bush. Always support the trailer safely, then follow current workshop procedures for Knorr SB and SN disc brake calipers. Use the recommended lubricants on pins and bushings, and discard any worn or damaged parts during the overhaul. Finally, check pedal feel and brake balance in a safe test area before the trailer returns to service.

Trailer Applications

You commonly find this caliper metal rubber bush 32mm on semi trailers, B doubles, dog trailers and other heavy combinations with Knorr disc brakes. Fleet operators use these bushes during scheduled brake relines or whenever the caliper shows excessive movement. Regular replacement helps maintain smooth caliper sliding, even pad wear and consistent brake response across the axle group. As a result, trailers stop more predictably and components often last longer between major repairs.

Cross-reference and Suitability

No specific cross reference numbers are currently listed for this bush. Instead, match by caliper family, bush length and diameter, and use current Knorr and axle guides to confirm suitability.
