Compatibility and Fitment

Match the outer diameter, disc thickness, centre bore, PCD, hole count and BPW brake type before ordering. Also check the existing rotor number and axle setup, because BPW TSB 3709 variants can differ by exciter ring provision.

Compliance and Safety

Inspect the hub face, mounting holes, brake pads, caliper hardware and wheel-end condition before fitting the new disc. Replace worn pads or damaged retaining hardware during the same brake service.

After installation, check disc runout, pad seating and brake operation before returning the trailer to service. Replace the disc if it reaches minimum thickness, shows continuous cracking or has braking surface damage outside the acceptable wear limits.

Trailer Applications

Workshops fit this 377 x 45mm brake disc during BPW ECO Disc trailer brake repairs, especially where the existing BPW TSB 3709 rotor has worn below service limits, cracked, scored or developed uneven braking surface wear.
