Complete Trailer Disc Brake Kit – Rotor, Caliper & Mounting Hardware – Axle Applications
Complete trailer disc brake kit including rotor, caliper, and mounting hardware. Designed for axle-based installations requiring reliable hydraulic braking performance.
Complete Hydraulic Disc Brake Solution
Upgrade from drum brakes to a smoother, more consistent braking system with improved heat control and performance under load.
|
Improved Braking Response
Disc systems deliver faster, more consistent stopping compared to traditional drum setups. |
Better Heat Dissipation
Open rotor design reduces heat buildup, minimizing brake fade. |
|
Simplified Maintenance
Easier inspection and servicing vs enclosed drum systems. |
Complete Kit Convenience
All major braking components included for install. |
R&P Knowledge Hub
Disc brake kits must match axle capacity, spindle size, and hub/rotor configuration for proper fitment.
Verify inner/outer bearing and seal compatibility before installation—this kit does not include them.
Installation Notes
Designed for hydraulic systems. Requires compatible actuator, brake lines, and correct bearing/seal setup. Calipers include integrated bleeder screws for proper system bleeding.
