Overview
This R&P Carriages custom hydraulic trailer brake drum kit is assembled for compatible hydraulic trailer brake applications requiring a 7" hub drum with a 5 on 4.5" wheel bolt pattern. The kit BOM includes one 008-271-07 hydraulic hub drum and one HD-200-KIT hub/drum bearing kit. Match the brake size, spindle, bearing setup, seal dimensions, wheel bolt pattern, pilot diameter, and axle rating before installation.
R&P Service Insight
Hydraulic brake drum fitment depends on the complete wheel-end setup, not just the axle capacity. Confirm your existing hub/drum and bearing measurements before ordering.
- Brake Type: For hydraulic trailer brake systems only, including compatible surge or hydraulic actuator setups.
- BOM Match: This kit is built from one 008-271-07 hub drum and one HD-200-KIT bearing kit.
- Fitment Check: Match drum size, bearings, seals, bolt pattern, pilot diameter, and spindle dimensions before installation.
R&P Knowledge Hub
Compatibility: Designed for compatible 7" hydraulic trailer brake drum applications where the hub drum, spindle, bearings, seals, and wheel pattern match.
Vehicle / System Fit: Trailer hydraulic drum brake systems using a 5 on 4.5" wheel bolt pattern.
Installation Notes: Verify bearing numbers, seal I.D. and O.D., spindle dimensions, pilot diameter, lug thread, and brake size before installation.
Performance Insight: The hub drum supports the wheel through tapered roller bearings while also providing the braking surface for hydraulic brake shoes.
R&P Custom Kit Note
Selling Brand: R&P Carriages Custom Kit
Application Reference: Custom 7" hydraulic trailer brake drum and bearing kit for compatible light-duty trailer wheel-end service.
What This Means: This listing is for one R&P-assembled wheel-end kit made from one hub drum and one bearing kit, not a bulk pack of loose individual components.
Before Ordering: Match this kit carefully to the trailer’s brake size, spindle, bearings, seals, bolt pattern, pilot diameter, and axle capacity.
R&P Repair Insight
When replacing a trailer brake drum, inspect the full wheel-end system before reassembly. A new hub drum should not be installed over damaged bearings, incorrect seals, worn brake shoes, or contaminated brake hardware.
- Inspect Bearings: Replace bearings that are pitted, discolored, loose, noisy, or heat damaged.
- Verify Seals: Match seal I.D. and O.D. to the spindle and hub bore before installation.
- Check Brake Shoes: Replace shoes if they are grease-soaked, cracked, unevenly worn, or below safe service thickness.
