Simple....Too much under hood heat, heating the brake system DOWNSTREAM from the M/C, expanding the fluid in the lines, just enough to have the same effect as riding the brakes. Expect it to happen again even w/the new parts. Add an electric fan to help move the hot air and/or crack the hood open letting it catch on the 2nd catch Rams by any chance w/ stock headers??? I have the same issue w/my F (had J/K headers) in high heat conditions. Won't run worth a crap when temps are in the 90's, even at highway speeds. The trip home from McCungie was a nightmare 2 years ago. Good luck!!

(New master cylinder and booster, less than 150 miles on them) Today she's fine. Any ideas?
