As far as talk about brake fade, I have never experienced that in my cars and the only time I have even been in a vehicle that had that problem was when my dad was using his pickup (don't remember year but it was a chevy half ton) to tow a 1968 Jeep Wagoneer down a steep hill and the jeep had no brakes and the second time was a few years ago with his current truck (1976 chevy 3/4 ton). He was towing a large (7' by 12') all wood shed down hill. (you probably don't want to know).
and the third time was in a work truck that didn't have the greatest of brakes (although the brakes were better than the clutch). It was a 1981 Dodge 3/4 ton club cab with a dump bed. We were towing a trailer full of lawn equipment (the trailer its self weighed 1200 pounds) and had 3200 pounds of grass in the back. Yes I am sure of those weights, we had to stop at the dump and unload when we came out we weighed 3200 pounds less than when we went in and we weighed 1200 pounds more empty towing the trailer than we normally did empty with out the trailer. So that 4600 pounds of extra weight woth bad brakes may have made a difference.
