A direct-fit replacement electric brake assembly for the right-hand (passenger) side of trailer axles rated 4,000 to 7,000 lbs. Purpose-built by Lippert for straightforward installation with no drilling or modification required when replacing worn or failed electric trailer brakes.
Worn or seized electric trailer brakes are a safety hazard and a common failure point on RV trailers, fifth wheels, and tow-behind units. The Lippert 298276 is engineered as a drop-in replacement for the right-hand side, restoring proper braking performance without the guesswork of adapting an incompatible assembly.
This assembly pairs a 12-inch drum diameter with a 2-inch shoe width -- a standard combination well-suited for axles in the 4,000 to 7,000 lb range. The 5-bolt mounting flange matches the most common spindle flange configuration used on trailer axles in this weight class, making it compatible with a wide range of manufactured-home, RV, and utility trailer applications that use Lippert or equivalent axle hardware.
Industry-standard 12-inch diameter by 2-inch wide shoe configuration matches OEM fitment on mid- to heavy-duty trailer axles.
Specifically designed for the right-hand side of the axle. Verify your brake side before ordering -- left-hand assemblies use a different part number.
Bolts directly to compatible spindle backing plate flanges with no drilling or modification required on properly matched axles.
Works with standard trailer brake controllers. The electromagnet engages the shoes when the brake controller sends a 12V signal through the vehicle's trailer wiring harness.
Electric trailer brakes use an electromagnet mounted inside the brake assembly. When the tow vehicle's brake controller sends current through the breakaway or brake wiring circuit, the magnet engages the drum and applies the shoes. This assembly is designed for 12V DC brake controller systems -- the same setup used on virtually all North American RV towables.
Confirm your existing brake controller is adjusted and functioning correctly before installation. A faulty controller that under- or over-applies current will shorten the lifespan of new brake assemblies regardless of brand.
This assembly is rated for axles in the 4,000 to 7,000 lb range. Common applications include:
Do not use this assembly on axles rated below 4,000 lbs (typically uses a smaller 10 x 1.75 or 10 x 2.25 drum) or above 7,000 lbs (may require a heavier shoe assembly or different hardware). Match the weight rating of your axle label, not the trailer GVWR.
Drum, hub, wheel, and mounting hardware are not included. This is the brake backing plate and shoe/magnet assembly only.
