I put new brake shoes on the front of my '65 Rambler American today, as a last effort to get the brake shoes from getting pulled out on the drivers side ( everything else is new ).. put them on and things fit better with these new 1's but.. I went to put on the drums and the pads are too thick to fit correctly, they just barely fit with the adjusters all the way in, and they drag really bad. what can I do? should I just drive off the extra material, or should I have the drums machined .002?
