Aftermarket right-hand hydraulic free backing brake assembly for 3,500 lb trailer axle applications using a 10" x 2.25" brake setup and 4-bolt mounting pattern.
Overview
This aftermarket hydraulic free backing trailer brake assembly is built for the right-hand side of compatible 3,500 lb axle brake systems.

R&P Service Insight
Hydraulic free backing brake assemblies are commonly used on surge brake trailer systems where reverse movement requires the brakes to release instead of locking up.
- Side Matters: This listing is for the right-hand brake assembly only.
- Size Check: Confirm your existing brake measures 10" x 2.25" before ordering.
- Mounting Check: Verify the 4-bolt backing plate pattern matches your axle flange.

R&P Repair Insight
Brake assemblies should be replaced when lining wear, corrosion, contamination, broken springs, or poor brake response make repair less practical than installing a complete replacement assembly.
- Confirm Orientation: Right-hand and left-hand trailer brake assemblies are not interchangeable.
- Inspect the Drum: A worn or damaged brake drum can reduce performance even with a new backing plate assembly.
- Service in Pairs When Needed: If one side is badly worn, inspect the opposite side for matching wear, contamination, or weak braking.
