12" x 2" Electric Trailer Brake Backing Plate Set – Two Axles (4 Plates)
A complete two-axle brake refresh in one listing. This 4-piece set includes two left-hand and two right-hand 12" x 2" electric backing plate assemblies so you can service both trailer axles with a matched, ready-to-install package.
Part Number: 12RVEB-2P 12" x 2" Electric Drum Brake Size 4 Plates • 2 Left • 2 Right • 5-Bolt
Overview
This 12RVEB-2P set includes four complete electric brake backing plate assemblies configured for two trailer axles using standard 12" x 2" electric drum brakes. Each assembly arrives built up with brake shoes, springs, adjuster hardware, and electric brake magnet installed, making this a strong choice when you want to refresh both axles at the same time instead of piecing together individual brake components.
Ideal for tandem-axle trailer owners who want to handle the brake job once, replace both axles together, and move forward with a cleaner, more complete service package.

Need Only One Pair Instead?
Not every trailer needs a full two-axle refresh. If you are servicing a single axle, replacing one left-hand and one right-hand assembly, or just want the one-pair version of this same brake family, we have that option ready.
Single-Axle Service 1 Left + 1 Right 12" x 2" Electric Brake Pair
The related 1 Pair listing is a strong fit for customers who want the same brake size and style without buying the full four-plate set.
R&P Service Insight
When tandem-axle trailer brakes are due, many owners prefer to service both axles together instead of replacing one side now and chasing the rest later. A complete four-plate set helps streamline parts planning, reduce downtime, and keep the brake hardware more uniform across the trailer.
- Two-Axle Coverage: This set gives you the four complete assemblies needed to service both axles on a tandem-axle trailer.
- Cleaner Repair Strategy: Replacing complete backing plates can be more straightforward than mixing worn components with new internal parts.
- Matched Brake Service: Refreshing all four backing plates together helps support a more consistent service baseline across the trailer.
R&P Knowledge Hub
Compatibility: Typically used on trailers with 5,200 lb, 6,000 lb, and 7,000 lb axles equipped with 12" x 2" electric drum brakes and a standard 5-bolt brake flange.
System Fit: This 4-plate configuration is intended to service two axles and includes the correct mix of two left-hand and two right-hand assemblies.
Installation Notes: Before ordering, verify brake dimensions, axle rating, flange pattern, and wiring condition. The most important checks are brake size, mounting pattern, and left/right count for your axle setup.
Performance Insight: Electric brake magnets, shoes, and internal hardware wear over time as a system. Replacing complete backing plate assemblies is a common service path when the goal is a more complete brake refresh.
R&P Repair Insight
The biggest ordering mistakes on multi-plate brake sets are usually simple: wrong brake size, wrong flange pattern, or wrong left/right quantity. This listing is specifically built for two-axle service with four complete assemblies, so it is a strong fit when you are refreshing a tandem-axle trailer using 12" x 2" electric brakes.
- Check 1: Confirm the trailer uses 12" x 2" electric drum brakes on each axle.
- Check 2: Verify each axle uses a standard 5-bolt brake flange.
- Check 3: Make sure your trailer needs two left-hand and two right-hand assemblies to service both axles.
