The truck has been to the dealer because the brakes would not immediately grabbing and the truck was taken to a dealer for repair of the rear backing plates which began to rust and break apart. This was repaired by the dealer. The dealer had to replace the brakes, calipers, and rotors along with this repair. Both rear brakes and housing assemblies were also replaced, the dealer noted they too were rusted. About a week after the repair while driving there was a hissing noise and thought that the tire may be going flat. The tire was not flat. The contact slowed at a stop sign, and when applying brake pressure there was a grinding and clanking noise each time brake pressure was applied. The contact drove home. Upon inspection of the vehicle noticed the caliper fell off and there was a grove on the rear drivers side rim. The vehicle has been back to the dealer. The dealer towed the vehicle back to the shop and determined there was a bolt from the caliper that had snapped and caused the caliper to fall off. The dealer is currently completing repairs on the vehicle. NHTSA recall NHTSA 05V379000 involving the anti lock brakes was issued, but contact was unsure if this vehicle was covered under the recall.

A bolt securing the rear left brake caliper bracket assembly failed catastrophically jammming the brake and the rear wheel while in motion. Fortunately this occurred at low speed and was controllable, but if it had occurred at speed on the highway, there would have been a major accident since the rear wheel could have suddenly seized with resultant loss of control of the vehicle (2002 4WD Suburban Z71).
