Confirm your backing plate: BP04-370 is listed for the Dexter 12-1/4" x 5" electric brake system with a stamped backing plate. Dexter also manufactures cast-backing-plate brake assemblies. These configurations can require different shoe and lining kits.
Confirm brake dimensions: The 12-1/4" dimension is the nominal installed drum brake diameter. The 5" measurement is the nominal shoe lining width. Both measurements matter when selecting replacements.
Confirm left versus right: This kit services the passenger-side brake assembly. Right-hand and left-hand configurations are not interchangeable simply because their dimensions match.
Inspect the remaining brake components: During shoe replacement, inspect the brake drum friction surface, actuating mechanism, adjuster, return springs, magnet and backing plate. Replace damaged or excessively worn components as required by the manufacturer's service procedures.
Installation: Follow Dexter's specified brake service procedures, including proper shoe orientation, hardware installation, drum inspection and final adjustment. Verify satisfactory operation before returning the trailer to service.

Replacing shoes on a heavy-duty trailer? Check both wheel ends on the axle for uneven wear, damaged springs, magnet condition, drum scoring or contaminated linings. Identifying the correct backing plate and assembly number before ordering can save unnecessary installation delays.
