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.

 The office of defects investigation (odi) received defect petition dp10-003 on march 2, 2010, requesting the investigation of model year (my) 2003 chevrolet silverado 2500hd 4wd pickup trucks for corrosion failures of the vehicle brake lines.dp10-003 was granted and on march 30, 2010, preliminary evaluation pe10-010 was opened on more than six million model year 1999 through 2003 light trucks and sport utility vehicles manufactured and sold by general motors corporation (gm).on july 2, 2010, odi received gm's response to an information request, which included gm's assessment of the frequency and safety consequences of the alleged defect. gm stated that:(1) the brake system of the subject vehicles is split front/rear and should a brake pipe suddenly fail for any reason, the affected vehicle would be capable of stopping with the pressure supplied by the remaining circuit; (2) the subject vehicles were designed to meet the hydraulic circuit partial failure requirements of federal motor vehicle safety standards 105 and 135, light vehicle brake systems; and (3) should a brake fluid leak occur for any reason, the brake system malfunction indicator lamp (mil) would illuminate and warn the driver before the brake fluid level was low enough to cause a loss of line pressure. of the890 total complaints for brake pipe corrosion identified, 761 were located in salt belt states (connecticut, delaware, district of columbia, illinois, indiana, iowa, maine, maryland, massachusetts, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, west virginia and wisconsin).the complaint rate per 100,000 vehicles sold is significantly higher in the salt belt, 43.0, compared with 3.0 for the remaining states.in approximately 25 percent of the complaints, the brake pipe failure has allegedly occurred suddenly, with no warning to the driver (i.e., no brake warning light), and resulted in extended stopping distances.in 26 of these incidents, the increase in stopping distance that resulted was alleged as a factor in a crash and in 10 others the vehicle was intentionally steered off the road or into another lane of travel in order to avoid a crash.an engineering analysis has been opened for subject vehicles sold or currently registered in salt belt states to further assess the scope, frequency and safety risks associated with sudden failures of corroded brake pipes that can result in decreased brake effectiveness. odi will continue to gather information on subject vehicles outside the salt belt as well.

 Brake line corrosion caused rapid loss of hydraulic fluid . steel line ruptured within a plastic retainer located on the left side of the car on the left frame rail directly behind the left front shock.. i have kept the exact ruptured part.. there were no signs of corrosion anywhere else on the vehicle in fact the rest of the line looks good.. the plastic retainer, for some reason excellerated the rate of corrosion in a small isolated area. i work in the automotive industry over 25 years experience.. i can assist in any information if needed...this problem will definately injure someone....
