A sticking or worn disc brake caliper can show up as the car pulling to one side under braking or a wheel that drags. Before replacing it, look the caliper over with the engine off for fluid weeping from the piston area or a torn dust boot, since tires and other brake parts can also pull a car sideways.
Fits
The 2006-2009 Chevrolet Trailblazer, 2006-2009 GMC Envoy and 2006-2007 Buick Rainier all take this front left caliper, and so do other vehicles.
