Compliance and Safety

Inspect the disc surface, pad thickness and mounting faces before refitting the brake assembly. Replace pads before the friction material reaches the minimum service limit, because worn pads can damage the rotor and reduce braking performance. Also check for continuous cracks, heavy scoring or uneven wear before returning the trailer to service.

Trailer Applications

Workshops fit this BPW disc rotor during trailer axle brake repairs where the existing rotor matches the 377mm, 8 hole, 275mm PCD configuration. For fleet servicing, compare the rotor against the axle identification and caliper type before ordering pads or hardware.
