Service brakes, hydraulic
Problem: Certain passenger vehicles were produced with lower than specified torque on both front brake caliper to steering knuckle attachment bolts. With improper torque, the clamp load at the joint may not be adequate to prevent movement between the caliper bracket and knuckle.
Risk: Depending on whether one or both bolts backs out or fractures, the result can be locking of the affected wheel during braking and an abrupt steering input in the direction of the locked wheel, reduced braking and noise from the affected wheel, or severing of a brake hose, increased brake pedal travel, and reduced steering control. Reduced braking or steering control could cause a crash.
Fix: Dealers are to tighten both bolts to the specified torque. Owner notification began on june 28, 2004. Owners should contact chevrolet 1-800-630-2438 or pontiac 1-800-620-7668.
