Carlson H2551 Drum Brake Self-Adjuster Repair Kit

Carlson H2551 is a drum brake self-adjuster repair kit for rear right drum brake service on select GM and Jeep applications. It is built for 11-inch x 2-inch drum brake setups and model 363 fitments where the adjusting spring kit and parking brake strut spring are part of the brake assembly.

Key Features

  • Drum brake self-adjuster repair kit for rear right service
  • Fits 11" x 2" drum brake configurations on select vehicles
  • Application coverage includes model 363 brake assemblies
  • Used on rear right drum brake adjusting spring and strut spring service
  • Carlson part number H2551 for brake maintenance and repair

Detailed Description

Brakes work as a system, and worn adjuster components can affect pedal feel, shoe adjustment, and parking brake operation. Carlson H2551 is designed for rear right drum brake repair on vehicles such as Chevrolet El Camino, Oldsmobile Cutlass, Pontiac LeMans, and Jeep Wagoneer applications listed below. This part number H2551 is specified for 11-inch drum brake assemblies and related 363 fitment configurations, making it a direct service part for restoring proper adjuster function.

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

What It Helps Fix

  • Brake shoe adjustment that no longer maintains proper clearance
  • Uneven rear drum brake operation on the right side
  • Parking brake strut spring wear in 11" x 2" drum systems
  • Noise or looseness from worn adjuster hardware
  • Service issues on model 363 rear drum brake assemblies

Installation Notes and Tips

Verify drum size, wheel cylinder bore, and brake model before ordering. Confirm rear right position and match the vehicle to the listed fitment, including 11" x 2" and 363 notes where shown. Inspect related brake shoes, drums, and adjuster components during service so the repaired assembly operates evenly after installation.

Quality Assurance

Carlson manufactures brake service components for repair-focused applications, and H2551 is cataloged for specific OE-style drum brake service use on listed vehicles.
