The brake drum kits are designed with a bolt pattern of 5 on 4.5" and come with 5 x 1/2"-20 studs installed. The kit also includes L68149 inner cone bearing and L44649 outer cone bearing, a grease seal of 1.719" x 2.565", an E Z lube grease cap with rubber plug, 5 cone wheel nuts with 1/2"-20 thread, and standard 10" x 2-1/4" electric brakes assemblies. The center hole diameter measures 3" and the mounting bolts circle diameter is 4".

The electric brakes work by activating the brake system when the towing vehicle's brakes are applied. The electricity is transferred from the towing vehicle to the trailer through an electric brake controller and wiring connection. Installation involves fitting the brake drum onto the axle hub, followed by the wheel. Care should be taken to ensure that all components, including bearings and seals, are correctly installed and lubricated with high-temperature grease. Regular maintenance includes inspection and cleaning of parts, checking for wear and tear, and timely replacement of worn-out parts.
