Drum Brake Adjusting Lever Return Spring

Carlson H2123-2 is a rear drum brake adjusting lever return spring for a wide range of GM applications. It is used in drum brake hardware assemblies where the self-adjuster and parking brake components must return and reset correctly.

Key Features

  • Rear drum brake hardware component for self-adjuster and parking brake assemblies
  • Fits a broad range of Buick, Chevrolet, GMC, Oldsmobile, and Pontiac applications
  • Application-specific fitment for 9.5 in. x 2 in. drum brake setups on listed vehicles

  • Carlson part number H2123-2 for direct catalog matching

Detailed Description

Carlson H2123-2 is a drum brake adjusting lever return spring used in rear brake hardware systems on select Buick Riviera, Chevrolet Camaro, Pontiac Firebird, and other GM models. Fitment includes vehicles with 9.5 in. x 2 in. drum brakes, along with several applications that reference 472 and 514 model numbers or related parking brake strut spring and self-adjuster repair assemblies. This part number, H2123-2, should be matched carefully to the listed brake configuration before ordering.

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

What It Helps Address

  • Weak or missing return action in the drum brake adjusting lever
  • Improper self-adjuster operation in rear drum brake assemblies
  • Parking brake hardware issues tied to worn spring components
  • Brake noise or inconsistent shoe adjustment caused by damaged hardware
  • Fitment problems when replacing worn rear drum brake springs on listed GM vehicles

Installation Notes and Tips

Confirm the brake configuration, model number, and dimensions before installation. Several listings note 9.5 in. x 2 in. drum brakes, 242 compatibility, or 472/514 hardware references, so verify the existing assembly against the vehicle application. Use the part number H2123-2 to match the correct rear brake hardware before service.

Quality Assurance

Carlson brake hardware is cataloged for application-specific replacement use, and this part number is listed across multiple GM rear drum brake configurations. Verify fitment details carefully to ensure the correct match for the brake assembly.
