Wilwood front brakes issues

It's entirely possible that they're on backwards. I should have been clearer when I said they only work 3/4 of the time. By that I meant that they cause some sort of problem (usually some scraping noise or slight dragging the other 1/4 of the time, but I have not been driving this car regularly starting about four months ago because it started seeping radiator and power steering fluid, which I fixed. On the subject of power brakes, I only know two people who have power brake a bodies and one of them got so tired of the inconsistency in the system that he just took the booster off and they work a lot better and more consistently now. I drive a slant six, and I'm not sure where the vacuum comes from for the booster, but I don't think I'd want to take any power away from the motor. Or add more variables to **** up somehow right now until I get everything else on the car in a solid place where I can start doing all the aesthetics and comfort projects. I've been driving the car with manual brakes for three years and have never had issues with leg power. Like I said, I need to go back and redo the whole brake system piece by piece according to the official direction packet.
