I've got a 65 with the mustang steve booster and willwood 4 pistons in the front and stock trash in the back. The pedal feel is all sorts of screwy and sometimes it gets really hard for no reason. I've bled everything but I'm wondering if the MC is the wrong type for a power brake setup and then I used 4 piston wilwoods instead of the one piston floater. I'm replacing the booster this weekend, but if anybody has any ideas if I might be running the wrong MC I'd appreciate a bit O' help here. My car stops pretty screwy and the pedal feel is so light I had to change out the brake light switch to the power one and even cut a whole coil off of it to get the lights to come on when I hit the brakes.
