A fully pre-assembled drop-in replacement electric brake for the right-hand (passenger) side of 3500 lb trailer axles. The backing plate arrives with shoes, magnet, and springs already installed -- cut the wires, swap the plate, reconnect, and you're done. No partial kits, no hunting for individual components.
Replacing a worn or seized electric trailer brake can be a frustrating job when you're sourcing springs, shoes, and magnets separately. Lippert's complete brake assembly solves that by shipping the entire unit pre-built on a new backing plate. The hardware is already positioned and tensioned at the factory, so installation is straightforward even for first-timers working in the driveway.
This assembly is specifically engineered for the right-hand (passenger) side of axles rated at 3500 lb. The 10-inch drum diameter is one of the most common sizes across single-axle utility, boat, and RV trailers -- making this a high-confidence replacement for a wide range of rigs.
Shoes, magnet, springs, and hardware come mounted on the backing plate. No separate assembly required before installation.
Meets Canadian Standards Association requirements for electric trailer brakes, confirming safety and quality standards.
Uses a standard manual star-wheel adjuster -- simple to set at installation and easy to re-adjust for even wear over time.
Engineered for the passenger side of the axle. Correct hand orientation ensures proper shoe arc and self-energizing action.
Because the assembly arrives pre-built, the swap typically follows these steps:
This brake assembly is designed for 10-inch electric drum brake systems on axles rated to 3500 lb. The 4-bolt mounting pattern with a 2.25-inch center hole is the standard configuration used by the majority of 3500 lb axle manufacturers. Verify your axle flange bolt pattern and drum diameter before ordering.
Common applications include single-axle RV trailers, boat trailers, utility trailers, and car haulers using 3500 lb axle assemblies. This right-hand assembly pairs with Lippert's left-hand version when replacing brakes on both sides of an axle.
