No Brakes

[bluezone]

I am having a problem with my powermaster system... I have brakes when i start the car & can drive it around...... The brakes work good has fluid.... But while driving sometimes the brake light will come on & about 20sec later i have no brakes at all... i was wondering what should i do...

Search for a Powermaster troubleshooting thread. I had the same issue last year. It turned out to be my motor going out. I replaced it and havent had an issue since.
