- Mounting Pattern: Verify your axle has a compatible 5-bolt brake flange.
- Side Orientation: This listing is for the right-hand / passenger-side brake assembly only.

R&P Repair Insight
If one brake assembly is being replaced due to wear or contamination, inspect the opposite side on the same axle as well. Uneven braking can be caused by mismatched adjustment, worn magnets, damaged wiring, contaminated shoes, or drum wear.
- Check the Drum: Inspect the inside braking surface and magnet contact area before installing the new assembly.
- Check the Wiring: Confirm the electric brake wiring and ground path are in good condition.
- Check the Pair: For balanced braking, many service jobs replace left and right assemblies at the same time when wear is comparable.
