Carlson H2628 Drum Brake Self Adjuster Repair Kit

Carlson H2628 Drum Brake Self-Adjuster Repair Kit restores the rear drum brake self‑adjusting mechanism in Carlson‑brand drum brake systems, replacing worn components to keep automatic adjustment functioning as designed. This rear‑side repair kit is described as compatible with rear left or rear right assemblies, depending on the vehicle, and is listed for Buick, Cadillac, and Pontiac rear drum brake applications in major catalogs. Marketed as OE‑quality, the H2628 focuses on refurbishing the self‑adjuster rather than replacing the entire brake hardware, helping promote even shoe wear and consistent braking performance. Use this kit when the self‑adjuster mechanism fails to maintain automatic adjustment, or when wear has degraded its operation, to restore proper drum brake function without a full hardware kit. Some retailers designate it specifically as a rear‑driver‑side option, while others note fitment for rear left or rear right assemblies; verify your vehicle’s drum brake configuration to ensure correct orientation. The H2628 part number is listed by Carlson and carried by multiple automotive parts retailers, reflecting its role as a dedicated repair option within Carlson’s drum brake service lineup.
