Description

Overview

Caliper guide pin and bush kit SN7 services the sliding hardware on Knorr SN7 and SK6 or SK7 style air disc brake calipers, as well as Bendix ADB22X units used on heavy trailers. By renewing worn pins and bushes together, the kit helps the caliper slide correctly so pads load the disc evenly and braking stays consistent.

Features

• Matched caliper guide pin and bush kit SN7 components so technicians can replace the full sliding set in one job and avoid mismatched wear.
• Precision machined pins that support smooth caliper travel under heavy axle loads and help maintain correct running clearance.
• Durable bushes designed to work with sealed guide arrangements so road grime, moisture and dust are better managed during service intervals.
• Convenient kit format that reduces parts selection time compared with ordering separate hardware items for each ADB22X or Knorr caliper.

Specifications and Materials

This caliper guide pin and bush kit SN7 supports floating caliper disc brake designs where the body slides on guide pins mounted in the carrier. High strength steel pins work with matched bushes sized for Knorr SN7 and SK6 or SK7 type calipers and Bendix ADB22X applications on truck and trailer axles.

Part number: FB2786.

Compliance and Safety

Brake technicians must follow vehicle and brake manufacturer procedures whenever they fit a caliper guide pin and bush kit SN7. Always support the vehicle securely, depressurise air systems where required and use the specified torque values on guide pin and carrier fasteners. Additionally, clean carrier bores carefully, inspect for corrosion or distortion and replace damaged carriers instead of forcing new pins into tight locations. Finally, move the caliper by hand after assembly to confirm free sliding travel before refitting wheels and returning the trailer to service.

Trailer Applications

Workshops typically use this caliper guide pin and bush kit SN7 on semi trailers, tankers, tautliners and dollies that run Knorr SN7 or SK6 and SK7 calipers or Bendix ADB22X disc brake systems. In many fleets these brakes sit on 22.5 inch disc axles across multiple trailer types, so a common guide pin and bush kit simplifies stockholding. Moreover, scheduling replacement with pad and disc changes helps reduce downtime caused by seized pins or uneven pad wear during busy periods.
