When do you know when the master is bad. Here is my problem, in the burnout box the car will creep out when the line lock is on. Also at the top end it just seems like the car will not stop at all and im doing all I can do to stop the car. It has 4 wheel disk brakes and all the rotors get so hot that they are turning color. I have a Wilwood master right now and was thinking of replacing it and trying that. Any help would be greatly appreciated.
