SERVICE BRAKES, HYDRAULIC

Manufacturer
GENERAL MOTORS CORP.
What Happened
Your vehicle has a brake booster that uses hydraulic fluid to help you stop. The booster's accumulator, which holds this fluid, might crack and break apart while you're driving.
Risk if Unfixed
If this happens, pieces could fly out and hurt you or others nearby. More importantly, the brake fluid could leak out, making it harder to steer and brake. This could cause an accident without warning.
Free Fix
The dealership will check your brake booster for free to make sure it's working right. If it's not, they'll replace it with a new one at no cost to you.

Original — What Happened
CERTAIN TRUCKS, SPORT UTILITY VEHICLES, AND VANS EQUIPPED WITH BOSCH HYDRO-BOOST BRAKE ASSEMBLIES, THE HYDRAULIC BRAKE BOOSTER PRESSURE ACCUMULATOR MAY CRACK AND SEPARATE FROM THE HYDRO-BOOST ASSEMBLY DURING NORMAL OPERATING CONDITIONS.
Original — Risk if Unfixed
IF A SEPARATION OCCURRED AND THE HOOD OF THE VEHICLE WERE OPEN, FRAGMENTS FROM THE ACCUMULATOR COULD CAUSE INJURY TO PEOPLE IN THE IMMEDIATE AREA. THE PRESENCE OF THIS CRACK OR FRACTURED SURFACE COULD ALLOW THE HYDRAULIC FLUID TO LEAK FROM THE ACCUMULATOR CIRCUIT OF THE BOOSTER ASSEMBLY. THE LOSS OF FLUID WOULD CAUSE INCREASED STEERING AND BRAKING EFFORT AND A CRASH MAY OCCUR WITHOUT PRIOR WARNING.
Original — Remedy
DEALERS WILL TEST THE HYDRO-BOOST ASSEMBLY FOR FUNCTIONAL OPERATION OF THE TWO-FUNCTION VALVE. IF THE HYDRO-BOOST ASSEMBLY FAILS THE TEST, DEALERS WILL REPLACE THE ASSEMBLY FREE OF CHARGE. THE RECALL BEGAN ON MARCH 23, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC TRUCKS AT 1-866-996-9463 AND HUMMER AT 1-800-732-5493.

SERVICE BRAKES, HYDRAULIC

Manufacturer
GENERAL MOTORS CORP.
What Happened
The brake hydro-boost system in your vehicle is a crucial part that helps you stop safely. The valve that regulates this system might be slightly too small, which could cause problems.
Risk if Unfixed
If the valve seal breaks, you might feel a slightly increased resistance when you press the brake pedal, and it could take a bit more effort to slow down or come to a stop. This could make driving more challenging, especially in emergency situations.
Free Fix
Your dealership will replace the faulty valve with a new one, free of charge. You should schedule the repair as soon as you get the recall notice.

Original — Risk if Unfixed
CONSEQUENTLY, THE VALVE O-RING SEAL MAY FRACTURE. STEERING EFFORTS MAY BE SLIGHTLY INCREASED WHILE BRAKING OR PARKING. UNDER CERTAIN DRIVING CONDITIONS, A FRACTURED SEAL MAY REQUIRE A SLIGHT INCREASE IN THE APPLIED BRAKE PEDAL EFFORT TO ACHIEVE THE SAME VEHICLE DECELERATION RATE AS PRIOR TO THE SEAT FRACTURE.
Original — Remedy
