Has anyone had their brakes actually almost get to the point of locking up during a race? This past Saturday we were really fast during practice and the heat race and the brakes were functioning properly. At the start of the feature, which was about 1.5 to 2 hoours after the heat race, the car was good, but quickly after that they started to drag some. On lap 7 there was a caution and then upon the restart the issue progressively got worse. When my son came off of the track after the 35 laps we lifted the front of the car and could not physically turn either one of the front wheels. We then lifted the rear and could turn the rear wheels slightly. I then went into the car and tried to work the brake pedal and it wouldn't depress at all. So I am pretty certain that it was a master cylinder failure. However I would like to know what caused it and if anyone else has ever experienced such an issue and what was found.
Thanks,
Mick
