R&P Knowledge Hub
Compatibility: Typically used on trailers with 5,200 lb, 6,000 lb, or 7,000 lb axles equipped with 12\" x 2\" electric drum brakes.
How Electric Brakes Work: Voltage from the brake controller energizes the magnet, which engages the drum surface and activates the brake shoes through the internal lever system.
Installation Notes: Confirm drum size, brake dimensions, flange bolt pattern, and wiring compatibility before installation.
Why Complete Assemblies Matter: Replacing the backing plate assembly restores the main wear components together, including shoes, springs, and magnet.
R&P Service Insight
Brake wear usually does not happen in isolation. If the shoes are worn down, the magnet and internal hardware are often due for attention as well. That is why complete assemblies are such a popular service option for single-axle brake work.
- Single-Axle Friendly: This pair gives you the left and right side needed to service one axle correctly.
- Less Guesswork: Replacing complete assemblies can simplify brake service versus mixing old and new internal parts.
- Balanced Repair: Servicing both sides together helps support more consistent brake response.
R&P Repair Insight
Before ordering, confirm the brake size stamped or measured on the trailer and make sure the flange pattern matches your axle. A few minutes of verification up front saves a lot of frustration once the drums are off.
- Critical Check 1: Confirm the trailer uses 12\" x 2\" electric drum brakes.
- Critical Check 2: Verify the axle uses a standard 5-bolt brake flange.
- Critical Check 3: Make sure you need one left-hand and one right-hand assembly for a single axle service.
