Keep your rear drum brakes self-adjusting at the correct clearance with the Carlson Drum Brake Self-Adjuster Repair Kit 12503. This kit renews the self-adjuster mechanism on the rear right (RH) drum brake and installs as a direct-fit replacement for the listed applications — including the 1983-1987 Toyota Tercel, 1984-2002 Toyota Corolla, 1985-1988 Chevrolet Nova, 1989-1997 Geo Prizm and 1998-2002 Chevrolet Prizm.
