My rear brake started locking up on me after 150 miles of owning this car, sat in the garage for a couple days and it's now locking up with the touch of the pedal. What is the proper or correct distance from drum pads to the drum? Do you just set so the pads barely allow the drum to fit on? Not sure if I should go as far as to put a caliper on each and give it a 1/16 gap before reinstalling.....or am I looking way to deep into this and just make it a snug fit back on!
