Description

Overview

Caliper adjusting adaptor caps 10 pack provides replacement caps for the manual adjuster adaptor on Knorr air disc brake calipers. These caps shield the adjuster from dust, moisture and road grime so the caliper keeps working smoothly. As a result, they support more reliable hand adjustment and help limit premature wear of internal adjuster parts.

Features

• Pack of 10 replacement caps so you can service multiple calipers in one job.
• Designed to fit the manual adjuster adaptor used on common Knorr air disc brake calipers.
• Helps keep contaminants away from the adjuster mechanism for more consistent brake performance.
• Suitable for workshop stock and fleet maintenance programs that standardise on Knorr air disc brakes.

Specifications and Materials

This kit supplies 10 caliper adjusting adaptor caps for service replacement on heavy-vehicle air disc brake systems. Each cap sits over the manual adjuster adaptor and forms a physical barrier against dirt and spray from the road.

Typical caps of this type use an oil-resistant polymer suited to high-temperature brake environments; always follow the caliper manufacturer’s guidance when confirming material compatibility. During pad changes or overhaul work, technicians normally renew these caps at the same time as other wear components.

• Quantity: 10 replacement adjuster caps
• Type: protective caps for manual adjuster adaptor on Knorr air disc brake calipers
• Typical use: service replacement during pad changes or full caliper overhaul

Part number: FB2888.

Compatibility and Fitment

Caliper adjusting adaptor caps 10 pack suits Knorr air disc brake calipers where a manual adjuster adaptor and protective cap sit on the caliper body. 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. SB 6/7 series, SN 6/7 series, ADB22X

Compliance and Safety

Always follow the vehicle and brake manufacturers’ procedures during brake service, including correct caging of spring brakes, wheel chocking and safe removal of caliper hardware. Additionally, use appropriate personal protective equipment when working around brake dust and cleaning the caliper area.

Next, inspect the adjuster area for corrosion, damage or missing components before fitting new caps, and replace any worn shear adaptors or adjuster parts at the same time. Finally, confirm brake adjustment with the specified method after refitting the caps so the running clearance stays within the recommended range.

Trailer Applications

These caps suit heavy trailers, semi-trailers and dollies fitted with Knorr air disc brake calipers in Australian linehaul, distribution and tanker fleets. They fit naturally into regular pad change intervals, so workshops can maintain adjuster protection while the vehicle remains in service.

Furthermore, fleet maintenance teams can hold caliper adjusting adaptor caps 10 pack on the shelf as a small, low-cost kit that supports consistent brake performance across multiple vehicles.
