Description

Overview of caliper guide pin and boot kit SB SN6 7

Caliper guide pin and boot kit SB SN6 7 services the sliding hardware on Knorr type SB6, SB7, SN6 and SN7 air disc brake calipers used on heavy trailers. The kit renews worn pins, bushes and boots so the caliper can float correctly and pads contact the disc evenly. As a result, fleets gain more consistent braking and reduce the risk of tapered or premature pad wear.

Features

• Matched guide pins, bushes and boots so technicians replace all sliding components together for predictable brake performance.
• Precision machined pins that support smooth caliper travel and maintain correct running clearance under heavy trailer loads.
• Durable bush and boot materials that resist road grime, moisture and brake dust for longer service intervals.
• Time saving kit format that simplifies parts selection instead of sourcing individual pins, bushes and boots from multiple lines.

Specifications and Materials

This caliper guide pin and boot kit SB SN6 7 uses high strength steel pins with matched metal or composite bushes and sealing boots suited to Knorr type trailer disc brakes. Each component matches the original carrier and caliper layout so workshop staff can service existing hardware rather than fitting a complete caliper assembly.

Part number: FB2783.

Compliance and Safety

Brake technicians must follow the vehicle manufacturer and brake system supplier procedures when fitting any caliper guide pin and boot kit SB SN6 7. Always support the vehicle securely, depressurise the air system where required and use specified torque values on guide pin fasteners. Additionally, clean carrier bores and mounting faces thoroughly, replacing damaged carriers instead of forcing new pins into distorted housings. Finally, check running clearance and pad travel after reassembly so the caliper slides freely before returning the trailer to service.

Trailer applications for guide pin and boot kit SB SN6 7 calipers

Fleets commonly fit this caliper guide pin and boot kit SB SN6 7 to European style semi trailers, tankers and curtain siders that run Knorr SB or SN type disc brakes. The kit also suits some rigid truck and dolly applications where SB6, SB7, SN6 or SN7 calipers operate on drive or trailer axles. Moreover, workshops that schedule caliper servicing with pad changes can use this kit to refresh sliding hardware at the same visit and reduce unplanned downtime.
