Bring firm, even clamping back to the rear left corner with the Raybestos R-Line Remanufactured Semi-Loaded Disc Brake Caliper and Bracket Assembly (MPN FRC11331).

It drops in as a direct-fit replacement for the 2002-2009 Chevrolet TrailBlazer, 2002-2006 Chevrolet TrailBlazer EXT, 2002-2009 GMC Envoy, 2002-2006 GMC Envoy XL, 2004-2005 GMC Envoy XUV, 2002-2004 Oldsmobile Bravada, 2003-2006 Chevrolet SSR, 2003-2008 Isuzu Ascender, 2004-2007 Buick Rainier, and 2005-2009 Saab 9-7X (all engines).
This floating caliper uses a single 1.89 in (48 mm) piston and an M10x1 bleeder screw thread in an aluminum casting. Country of origin: Mexico. Sold individually for the rear left position; replacing calipers in axle pairs is recommended for balanced braking. If a seized or leaking rear left caliper is the cause of your braking issue, this assembly replaces it.
