The Lippert 296652 is a fully assembled, forward self-adjusting electric drum brake designed for the right-hand (passenger) side of your trailer. It automatically corrects shoe-to-drum clearance during every forward stop, delivering up to 50 percent better braking distance compared to manual-adjust brakes -- a critical safety advantage during emergency panic stops with a loaded trailer.
Manual brake adjustment is easy to neglect, and worn clearance means longer stopping distances when you need stopping power most. Lippert's forward self-adjusting mechanism eliminates that variable by automatically resetting lining-to-drum clearance every time you apply the brakes in the forward direction. The result is consistent, predictable stopping throughout the life of the lining -- not just right after a manual adjustment.
Part number 296652 is the right-hand assembly. It mounts to the passenger side of your trailer axle and is engineered for axle weight ratings between 4,000 and 7,000 lbs, covering a wide range of travel trailers, fifth wheels, and toy haulers running common 14.5", 15", or 16" wheel sizes.
Auto-set mechanism corrects shoe clearance on every forward stop, maintaining optimal pad-to-drum contact without manual intervention.
Consistent clearance translates to up to 50 percent shorter stopping distances compared to out-of-adjustment conventional electric brakes.
Backing plate, shoe and lining kit, magnet kit, adjusting screw, and spring hardware all included and pre-assembled -- bolt on and wire up.
Rated for 4,000 to 7,000 lb axles. Fits 14.5", 15", and 16" wheels on a standard 5-bolt hub mounting pattern.
Traditional electric drum brakes use a fixed adjuster that must be manually turned to compensate for lining wear. Once lining wears down even slightly, the shoe-to-drum gap increases and braking force drops. Lippert's forward self-adjusting design uses a lever and adjuster screw mechanism that automatically ratchets the shoes outward during every forward brake application. This keeps the drum-to-lining clearance in the ideal range throughout the wear life of the shoe -- no crawling under the trailer with a screwdriver required.
This design also promotes even magnet wear because consistent contact geometry keeps the electromagnet seated properly against the drum surface on every application.
This assembly arrives ready to mount. You will need to supply a compatible brake drum and hub separately if you are not reusing your existing drum, and standard trailer wiring connectors for the magnet leads.
The 296652 is designed for standard electric brake axles with a 5-bolt hub bolt pattern and a 12" brake drum. It is compatible with axles from major manufacturers (Dexter, AL-KO, Lippert/LCI) that use a 12" x 2" electric drum configuration in the 4,000-7,000 lb capacity range.
