I have a ke70 1983 sedan and i was driving around the other night and i pulled over to have a smoke and I looked down at the front wheels and smoke was coming from the brakes so I had a look and the brakes were glowing red so i waited till they cooled down. I started driving home and went to put the brakes on and they didn't work the pedal went all the way to the floor. so i got home and waited about an hour I jumped back in and the worked. can some one tell me what would of caused them to stop working and then magically just start working?
