DETROIT, Mich (WKBN) -The National Highway Traffic Safety Administration is urging people in 20 cold weather states, mostly in the Northeast, and Midwest, to get the undercarriages of their cars and trucks washed during and after the winter, along with getting their brakes lines inspected.
NHTSA says that road salt and a lack of washing can result in rusting pipes that could leak brake fluid and reduce braking power.
They recently closed a five year investigation into these rusting pipes in nearly 5-million older model vehicles, and determined it was not the result of a manufacturing or design defect.
The car wash advisory highlights how important it is to wash the corrosive material from under your car, because over time the salt can cause suspension parts, the frame, or other components to corrode and fail.
In the mid-2000’s, the automotive industry began to gradually switch to nylon and plastic-coated steel lines, which helps with the rust problem.
