Important Notes Verify axle rating, 4.75" pilot diameter, bolt pattern, spindle configuration, flange mount, wheel / hub style, and hydraulic compatibility before installation. Overview This 2-H-11-10Q-RDDD hydraulic trailer disc brake kit is intended for compatible 10,000 lb Quality / Rockwell American style trailer axle applications where the rotor, hub / spacer, DBC-338-D caliper, CMB-11-10Q-D bracket, and 4.75" pilot configuration match the existing setup. It is a two-wheel brake kit for service replacement or conversion work where all fitment points are verified before installation. R&P Service Insight Heavy-duty disc brake fitment is measurement-driven. Similar 10K hub / rotor assemblies can use different pilot diameters and caliper generations, so the center bore and component references should be checked before ordering. 4.75" Pilot Check: This listing is for the 4.75" pilot / center bore version. DBC-338-D Check: This listing uses the DBC-338-D caliper reference, not a K71-DBC-2250 caliper listing unless separately verified. System Check: Confirm actuator, brake line routing, fittings, fluid compatibility, and bleed procedure before installation. R&P Knowledge Hub Compatibility: Designed for compatible 10K Quality / Rockwell American style trailer axle hydraulic disc brake applications using the 2-H-11-10Q-RDDD configuration and 4.75" pilot / center bore. Vehicle / System Fit: Used on heavy-duty trailer hydraulic brake systems where the spindle type, hub / rotor style, DBC-338-D caliper reference, caliper mounting bracket, pilot diameter, and hydraulic components match. Installation Notes: Requires compatible hydraulic actuator, brake lines, fittings, brake fluid, and proper bleeding after installation. Verify all mounting and rotating components before road use. Performance Insight: Hydraulic disc brake systems are commonly selected for heavy trailer applications where serviceability, heat management, and consistent braking response are important. Brand & Fitment Note Selling Brand: R&P Carriages Application Reference: 2-H-11-10Q-RDDD, 2-ROTOR-11-10Q, DBC-338-D, CMB-11-10Q-D, H/S-99-475-D-S, Quality, Rockwell American, Dexter, and Kodiak references are used only for compatibility, identification, and application matching. What This Means: This listing is for the brake kit described here. Do not assume genuine OEM, factory original, or exact interchange status unless separately verified. Before Ordering: Confirm axle rating, 4.75" pilot hole diameter, spindle type, bearing and seal fit, brake flange / bracket compatibility, hub / rotor style, and hydraulic brake system requirements. R&P Repair Insight Before replacing a 10K disc brake assembly, inspect the current hub / rotor, caliper bracket, caliper clearance, spindle journals, seal surface, brake lines, actuator condition, and wheel fit. Similar 10K disc brake kits can look alike while using different pilot diameters, caliper styles, and hub configurations. Pilot Verification: Measure your existing pilot / center bore and confirm it matches 4.75". Caliper Verification: Confirm the DBC-338-D caliper configuration is the correct version for your setup. Spindle Verification: Confirm #99 spindle style, bearing, seal, cap, and wheel compatibility before installation. Hydraulic Verification: Confirm actuator size, line condition, fittings, fluid, and bleed procedure before use. Features 10K Hydraulic Disc Brake Application Built for compatible 10,000 lb trailer axle hydraulic disc brake service where the listed fitment points match. 4.75" Pilot Version This listing is configured around the 4.75" pilot / center bore reference for the 2-H-11-10Q-RDDD application. DBC-338-D Caliper Configuration Uses the DBC-338-D hydraulic disc brake caliper reference shown for this kit configuration.
