Chevrolet Monte Carlo, Impala: Brakes
Affects Chevrolet Monte Carlo, Impala · 2004 — about 3K vehicles.
The hazard
On certain vehicles, two bolts that attach the front brake caliper to the steering knuckle on the left and right front wheel assemblies were not tightened adequately. If too much movement occurs between the caliper bracket and knuckle, the bolt(s) may back out or fracture. Depending on whether one or both bolts back out or fracture, the result can be: 1) locking of the affected wheel during braking and an abrupt steering input in the direction of the locked wheel, 2) reduced braking and noise from the affected wheel, or 3) severing of a brake hose, increased brake pedal travel, and reduced steering control. If this were to occur, it could result in a vehicle crash without prior warning. Correction: Dealers will tighten both bolts to the specified torque.
