For compatible 3,500 lb trailer axles, Lippert's 10 × 2¼-inch forward self-adjusting electric brakes come as distinct left- and right-hand assemblies. Their backing plates use a four-bolt mount, and the brake's internal adjuster helps maintain shoe clearance during forward stops. Match the assembly number and side before ordering.

Before ordering
The 296649 left and 296650 right brake assemblies are separate order numbers; each listing is for one side, not a pair. Confirm the 10-inch drum diameter, 2¼-inch shoe width, four-hole mounting flange, 3,500 lb axle specification and the electric brake wiring. The separately shown 136454 magnet is not a complete brake. The factory parts catalog identifies other service pieces, but they must match the particular installed brake.
