Description

Overview

BPW upper dust cover 4218 120sq right-hand helps keep road grit and moisture away from the drum brake area on compatible BPW axle assemblies. This supports cleaner inspection and can reduce contamination around the shoes and drum. Because brake position matters, this upper right-hand cover suits the 16° cam position on 120sq square-beam axles when the brake type uses the 4218 layout.

Features

• Matches the BPW 4218 pattern for 120sq axle beam and 16° cam position selection
• Protects the brake assembly so linings and drums stay cleaner for longer
• Supports routine checks via inspection openings where fitted
• Installs as a direct dust cover replacement during brake service work

BPW upper dust cover 4218 120sq right-hand suits scheduled brake maintenance when you are replacing damaged or missing covers.

Compatibility and Fitment

Confirm your brake position and cam angle before ordering because an upper cover will not swap with a lower cover. Also check that your axle beam is 120sq and that the dust cover sealing edge matches the drum you run. This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown, but some changes in installation may be required. 0301099570, 0301081290

Compliance and Safety

Braking components are safety-critical, so use a competent technician and follow the axle manufacturer’s workshop procedure. Inspect shoes, drums, and hardware at the same time, then torque fasteners to the correct specification. Keep friction surfaces free of grease and debris, and replace worn components rather than forcing a fit.
