Product Details

PowerStop L7104 is part of the Autospecialty OE Replacement Brake Caliper line, which is focused on direct replacement for stock brake components. For drivers searching for a front left brake caliper for 2014-2020 Acura RLX or a front left brake caliper for 2013-2018 Acura RDX, this unit provides the OE-style fit and construction needed for routine brake restoration. The remanufactured caliper and bracket are assembled with new service components and pressure tested before release.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

  • Brake fluid leaks from a worn or damaged caliper
  • Uneven braking caused by a sticking piston or slide issue
  • Poor pad contact from corroded or seized caliper components
  • Reduced braking performance from a failing front left caliper
  • Noise or drag related to worn caliper seals and boots

Installation Notes

Verify vehicle-side fitment before installation. This caliper is for the front left position only and should be matched to the correct Acura RLX or Acura RDX application. Inspect brake pads, rotors, and brake hoses during service, and bleed the hydraulic system after installation to remove air from the lines.

Because the caliper is remanufactured with a bracket and slides included, it is suited for a direct replacement workflow on compatible vehicles. Confirm bleeder screw thread size and mounting points during brake system service.

Quality Assurance

PowerStop remanufactures the calipers and brackets in Chicago, IL and pressure tests each unit to verify piston operation and check for leaks. The assembly process uses new seals, slide pins where applicable, dust boots, bleeder screws, and stainless steel brake pad abutment clips to support consistent brake service quality.
