R&P Service Insight
Brake assemblies should be matched by specification, not by appearance alone. Before installation, compare the existing assembly to this listing and confirm the drum and flange setup are correct.
- Measure First: Confirm your existing brake size is 12" x 2".
- Check Orientation: This listing is for the left-hand assembly.
- Inspect the Drum: A new brake assembly should not be installed against a badly worn, deeply grooved, or contaminated drum surface.
R&P Knowledge Hub
Compatibility: This brake assembly is intended for compatible 12" x 2" Dexter electric drum brake applications with a 7,000 lb capacity rating and left-hand orientation.
Trailer Brake Fit: Verify the axle rating, brake size, brake flange bolt count, hub/drum compatibility, and side orientation before ordering.
Installation Notes: Inspect wiring, magnets, shoe wear, drum condition, bearings, seals, and brake adjustment during service.
Performance Insight: Electric brake assemblies use a magnet and actuating arm to expand the brake shoes against the drum surface when voltage is applied from the trailer brake controller.

R&P Repair Insight
A weak or uneven trailer brake can be caused by worn shoes, a weak magnet, damaged wiring, a contaminated drum, poor adjustment, or mismatched left/right assemblies. Check the full brake system before replacing parts.
- Left vs. Right: Brake assemblies are directional. Match the side before installing.
- Drum Condition: Grease, scoring, heat damage, or uneven wear can reduce braking even with a new assembly.
- Balanced Service: If one side is heavily worn, inspect the matching right-hand assembly and consider servicing both sides of the axle.
