pulling to the right

What Dana didn't mention is they will not auto-unadjust, if they were accidentally tightened too much on renewal
Good point,

And they might work fine till they get super hot.

On a side note I was having issues with my rear drums on a 8 3/4 swap. WELL used drums - turned, used shoes, cleaned and lubed everything else.

I finally got it all worked out, but in the process I had the rear on stands and had the engine running and trans in reverse.

Had my wife stab at the brake pedal a few times and for the first time in my life got to watch the auto adjusters actually function.

Gave me goose bumps!
