I would like to respond to "Agency: Wash your car" [News, April 10], about the National Highway Traffic Safety Administration's investigation of rusting pipes that carry brake fluid in older Chevrolet, Cadillac and GMC pickups and SUVs.

I'm amazed it took five years to investigate 3,645 complaints of rusted brake lines. Even more amazing was the recommendation to wash our vehicles more often.

I own a 2004 Chevrolet Suburban that needed to have its brake lines replaced because of this problem. It cost me almost $3,000 to replace all the lines with stainless steel tubing. When I was shown the old lines, they looked like Swiss cheese. The rest of the undercarriage showed no signs of corrosion. The dealership that did the work told me it was averaging two vehicles a week with the same problem.

The previous two Chevrolet Suburbans I owned had no problems with the brake pipes rusting, and each had more than 100,000 miles. I drove them in the snow, ice and the winter weather of Long Island.
