I'm replacing the brake pads and drums on my 74 fj40. I have the new pads on but I can fit the hub over them. I try to adjust the wheel cylinders in a little, cause I'm figuring they were probably all the way out, but I only get about a quarter turn before it stops. I've tried walking the adjuster cog forward with a chisle and mallet but still nothing. I don't want to bang it too hard and bust up the cylinder. How far is the wheel cylinder supposed to be able to turn? Should I take the new pads off and try to adjust the cylinders down without them?
