Defect SummaryCertain 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.
Consequence SummaryIf 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.
Corrective SummaryDealers 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.

Defect SummaryCertain sport utility vehicles, pickup trucks, and passenger vans fail to comply with the requirements of federal motor vehicle safety standard no. 135, ?passenger car brake systems.? some of these vehicles were produced with an out-of-specification brake hydro-boost housing relief valve bore.
Consequence SummaryConsequently, 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.
Corrective SummaryDealers are to replace the hydro-boost relief valve. the recall began on june 18, 2004. owners should contact cadillac at 1-866-982-2339; chevrolet at 1-800-630-2438; gmc at 1-866-996-9463; or hummer at 1-866-486-6376.

 While driving/ braking normally, brake pedal sunk down to floor. luckily i was driving slow and no other cars were around because stopping at 30 mph took a very long space. i found out that 1 brake line rotted through till it leaked and 3 others needed replacement. gmc does not make replacement lines they need to be custom made. *tr

 Dt: the contact owns a 2004 yukon xl which he had owned for eighteen months with about 12,000 miles on it. the rotors had rusted and pitted on all four wheels. the dealer said they must be replaced. gm said they were not responsible for brakes and called this an environmental wear problem. the contact was informed of this on 10-06-05 during a routine service check. the contact thought this was a defect in the brakes on because the rotors should have not have worn out with only 12,000 miles on the car.*ak updated 11/15/2005 - after the consumer indicated he was going to call nhtsa he received a call from an area rep. the rep indicated that gm approved replacement of the front rotors and cleaning of the rear brakes under warranty. *nm
