13 Brake Hoses, Lines/piping, And Fittings problem

Failure Date: 08/19/2012

The 2005 GMC 2500hd fwd (well maintained and oiled to prevent corrosion) experienced a failure while towing my 24' pursuit fishing boat (7200 lbs. ) home from sturgeon point marina to hamburg, NY 14075 (approximately 10 miles) with "minimal" stopping capability as the dot 3 brake fluid was being expelled. I had to feature the throttle to negotiate stopping senarios without issue. As of 8/20/12, this vehicle is with fuccillo Chevrolet, inc. (grand island, NY) for overhaul of entire braking system; including fuel lines. The certified technician suggested the entire brake lines system be replaced along with the fuel lines due to extreme corrosion. All this work is being performed since the excellent condition of the vehicle. The estimate for this work is approximately $2250 to replace all lines (brake / gas) affected by severe corrosion. This condition is a result of poor material selection not capable of withstanding normal winter conditions found in the northeast. The same standards should be used as selecting exhaust system material. Brakes can kill you. . . . Exhaust systems can not! final note: truck driven 50 miles per week to work (10 miles each day). During winter months, the residual salt is rinsed as required on a weekly basis (or sooner) to prevent corrosion. This truck prior to winter driving has had oil applied to the underframe, apparently, the brake / fuel line where not adequately treated.

Failure Date: 01/01/2009

I bought my GMC Sierra 2500 in June of 2005. Shortly after I bought the truck I started to notice rust on the trailer hitch and frame rails. As the years have gone by, the entire undercarriage is rusted over. Over the last several years a brake line rusted through and the brake pads & rotors have been replaced several times. I was lucky to be picking my truck up from the shop after an oil change & not driving it, when I noticed brake fluid on the ground under my truck. My speedometer does not work properly & the dashboard lighting works occasionally. My trailer hitch rusted so bad that the last time I put the receiver into the hitch it was stuck & I had to get a friend to connect a chain to his truck & while I drove forward & he reversed, the receiver finally broke free after approx. 10 minutes.
