I really don't understand this one. I bought it new a few months ago. It's a B&M if that matters and it just won't hold my car still. I see other people with insanely powerful cars and they can sit in one spot all day. I have regular street tires, the front brakes rotors, pads and lines are brand new and I'm still moving at 5 or 6 mph..... I think I know how to use it but after all the times I messed with it, I only got it to stand still once. Any Ideas? 


I say pump that pedal, and hold very hard, then flick the switch. If you have no air in the lines or calipers, and no leaks, you won't move.
