did you fade the pads or the fluid?
faded pads will NOT stop...
faded fluid will make the pedal feel like complete mush, but it will, sorta, slow down.
my guess would be fluid. You shouldn't be able to fade oem pads at an autocross, much less pads built for performance on your drive home.
Fluid should be replaced at least every year, and use a good fluid. I like Valvoline's DOT4 stuff. Cheap, available.
