Description

Overview of caliper adjuster mechanism 10mm hex

The caliper adjuster mechanism 10mm hex restores automatic adjustment inside Knorr SB6, SB7, SN6 and SN7 trailer disc brake calipers. This mechanism controls pad to disc running clearance and keeps lever travel consistent as pads wear. As a result, it helps maintain firm pedal feel and stable braking on loaded trailers.

Features

• Suits Knorr SB6, SB7, SN6 and SN7 trailer disc brake calipers used on heavy vehicle axles.
• Caliper adjuster mechanism 10mm hex drive for straightforward service with the correct tools.
• Supplied as a complete internal adjuster assembly ready for installation into the caliper body.
• Supports preventative brake maintenance programs and helps reduce unexpected caliper replacements.

Specifications and Materials

This caliper adjuster mechanism 10mm hex assembly suits Knorr SB6, SB7, SN6 and SN7 air disc brake calipers on European style trailer axles. It uses a 10mm hex drive on the adjuster so technicians can set the mechanism with the correct tool. The adjuster works with the caliper lever and tappet to keep pad clearance within the intended range as friction material wears. Part number: FB2877.

Compatibility and Fitment

This caliper adjuster mechanism 10mm hex suits Knorr SB6, SB7, SN6 and SN7 calipers with a 10mm hex internal adjuster. Always compare the removed adjuster and confirm the caliper identification marks before installation. This cross-reference listing shows that this part can replace the part numbers and applications shown. Some changes in installation may be required. CKSK104, 170K0164

Compliance and Safety

Technicians treat the caliper adjuster mechanism as a critical part for keeping pad clearance within the range specified by brake manufacturers and road authorities. During service, technicians should verify that the automatic adjustment function operates smoothly. They should also check for binding, abnormal play or signs of internal damage. Additionally, always follow the published procedures for backing off, resetting and checking air disc brakes so torque settings, lubrication points and test steps stay consistent with official guidance.

Trailer applications for caliper adjuster mechanism 10mm hex

Workshops use this caliper adjuster mechanism 10mm hex on semi trailers, B double combinations and other heavy trailers that run Knorr SB or SN series disc brake calipers. In addition, they often replace the adjuster during full caliper overhauls where technicians renew tappets, boots and pad hardware at the same time. Consequently, fleet operators can align brake performance across multiple trailer positions and reduce downtime linked to uneven pad wear or excessive lever travel.

Cross-reference and Suitability

This part cross-references to or suits the following equivalent part numbers and compatible alternatives:

Before final fitment, confirm the existing caliper type, adjuster style and linkage arrangement so this caliper adjuster mechanism 10mm hex matches the brake hardware on the vehicle.
