The brake system in your vehicle relies on a small valve to help control the brake fluid. In some 2004 models, this valve was made with a slightly incorrect part that could cause problems.
Risk if Unfixed
If the valve seal fails, you might need to press the brake pedal a bit harder to slow down or stop. This could make it harder to stop your vehicle, especially on hills or when you need to stop quickly.
Free Fix
Your dealer will replace the faulty valve with a new one at no cost to you. Just contact Cadillac, Chevrolet, GMC, or Hummer to schedule the repair.
