Brakes got progressively "soft" on the way home, until eventually the pedal went to the floor. Made home by going slow and downshifting to decelerate without using the brakes. Problem diagnosed to be the master cylinder.
As I was leaving my home there was a complete loss of brakes in my driveway. After checking I discovered that the brake line had burst due to corrosion. I had a hard time trying to understand how there could be a complete loss as all vehicles now have a dual line master cylinder. I then remembered I had seen a oily spill and trail up the shared gravel drive several months ago. Apparently I had lost half the brake system months ago. There was no warning light or different feel to the brakes during this time. I managed to get the truck in the garage and while checking what was needed for repair I discovered that every single brake line on the vehicle needs to be replaced. I have another Chevrolet pickup that I bought new in 1989 and the brake lines are in better shape than the 2005's.
Noticed my brake lines coming out of the brake master cylinder are rusting ! these lines are not near the road [ chemicals/ road salts ] but are in the engine compartment. My truck is located and driven in southern California in a warm location [ not in the mountains and winter cold]. I will have to check the rest of the lines and do something before they rust thru and cause an accident. This is a safety issue.
