Brake Hoses, Lines/piping, And Fittings problems of the 2001 Chevrolet C/k 3500

Came close to hitting an so cruiser in back when front brake lines blew out on left frame and at front wheel ,wondering if gm is doing anything about this problem ,been reading on google that it seems a lot of people are having the same thing going on looked at rest of lines and they are all almost rusted away ,I don't understand this I have a 1996 s10 blazer and the lines are just fine on this old of a vehicle ,I can't find anywhere there has been a recall ?.

Driving approx 35 mph brake pedal went to floor, pedal was spongy and no real braking power. Found brake lines rusted thru and other signs of corrosion under body. Replace two lines. On October 24, 2012 truck lost braking power again. Found more rusted out lines.
