Rear Brake Kit for Acura RLX

Dynamite Friction DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware, part number 4512-58039, is a rear disc brake kit for 2014-2020 Acura RLX applications. It combines coated rotors, ceramic brake pads, and matching brake hardware in one service package for a complete rear brake refresh.

  • Fits 2014-2020 Acura RLX, rear
  • DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
  • Dry-processed rotors arrive ready to install
  • Non-directional rotor finish supports even pad bed-in and smoother braking
  • DFC 5000 Advanced ceramic pads are post-cured and scorched for stable friction
  • Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness
  • Hardware kit uses PTFE coating, vulcanized rubber, and stainless steel

Product Line Details

The DFC GEOSPEC rotor line is built to OE specifications using G3000/G11H18 cast iron, then machined to tight tolerances and inspected for critical dimensions and balance. The 5000 Advanced pad line is formulated for consistent friction performance and reduced break-in effort, making it a practical choice for drivers servicing the rear brakes on an Acura RLX.

Common Brake Service Issues

  • Rear brake noise during stops
  • Rotor rust and surface corrosion
  • Uneven pad wear or inconsistent pedal feel
  • Vibration from worn or out-of-spec rotors
  • Reduced braking performance from fatigued hardware

Installation Notes

Fits 2014-2020 Acura RLX, rear. This rear brake kit is intended for direct brake service on the rear axle and is designed to simplify replacement of rotors, pads, and hardware together. Verify rotor size, caliper condition, and vehicle brake configuration before installation. The dry rotor coating is removed naturally by the pad friction during normal use.

Quality Assurance

Each DFC GEOSPEC rotor is 100% inspected after machining, with vented rotors balanced and corrected as needed. The rotors carry a 12-month warranty against defects in material and workmanship. Part number 4512-58039 is built for OE-style fit, finish, and braking consistency on the Acura RLX rear axle.
