Rear drum brakes
Answer
Clearance? What are you measuring and how do you expect to do that? You're basically just tightening them until they drag a little.
I know to adjust to it drags, i was asking if there is a clearence that you use a filler gauge just like you do on a Mitsubushi FM the clearens is .006th and you ch it through the inspection hole.
Most vehicles don't have inspection holes. It's a self adjusting system so all you need is a starting point.
Never heard of using a feeler gauge for the brakes on any car. Once you have a slight drag, or even close, the self adjusters will take care of themselves after that. Once the linings begin to wear, you can expect to have lining-to-pad clearance in the area of sixteenths of an inch before the adjusters take another bite, not thousandths of an inch. You'll never notice that in the brake pedal. Just get those babies close and call it good.
