Overview
This electric brake assembly is a replacement right-hand brake solution for trailer applications using a 10 inch x 2-1/4 inch backing plate, new style flange, and 4,400 lb axle setup. It is a practical choice when replacing a worn, damaged, or non-matching passenger-side brake assembly, and it includes hex head nuts and rubber plugs to support installation on compatible setups.
R&P Service Insight
Brake assembly swaps are much easier when side orientation and flange style are confirmed before install. Right- and left-hand assemblies are not interchangeable, and even a correct brake size can still miss the axle if the flange style is wrong.

- Hardware Included: Includes hex head nuts and rubber plugs as listed for this assembly.
- Fit Check: Confirm backing plate size, axle capacity, and new style flange details before removing the old unit.

Brand & Fitment Note
Selling Brand: Not specified
Application Reference: Any OEM or platform names in this listing describe compatibility, fitment target, or application style only where supported by verified dimensions, mounting points, and configuration details.
What This Means: This listing is for a right-hand electric brake assembly, not a guaranteed fit for every 4,400 lb trailer axle unless the brake size, flange style, side orientation, and mounting details match your current application.
Before Ordering: Verify measurements, mounting style, orientation, connector style, axle/brake/hub specifications, and included components before installation.
R&P Repair Insight
Most brake assembly ordering errors come from choosing the wrong side, assuming axle capacity alone guarantees fit, or overlooking flange differences. Double-check the existing brake before purchase so the replacement matches the passenger-side application you are servicing.
- Right vs. Left: Confirm you need the right-hand assembly before ordering, since the opposite side uses a different brake assembly.
- Flange Verification: Make sure your axle uses the new style flange listed for this brake assembly.
- Included Parts Review: Confirm the included hex head nuts and rubber plugs match what you need for your installation.
