front discs locking up

I knew my brakes were dragging because my car just didn't coast like it used to. At first I spent a lot of time adjusting the rear drum brakes because for some reason I thought it was the rear brakes that were dragging. Finally I realized it was the front K-H discs, on both sides. Then I read this thread and learned more about how the system works. I was then able to cure the problem by removing my brake light switch. The problem was caused by all the lost motion in the pedal and pushrod assembly. Due to that slop, it was necessary to get the brake light switch too close to the pedal in order to actuate it, so the body of the switch was then preventing the master cylinder from returning to its normal position. I've removed the pedal assembly and am re-sizing both holes.
