Hi gang,

I'm a bit confused regarding adjusting the rear shoes after replacing the wheel cylinders.

I was able to yank the drum off without bringing the shoes in on one side but the other I had to play with that little shoe adjustment wheel to bring the shoes in before the drum would pop back on. I am reading in the FSM that pulling the e-brake a few times adjusts the shoes back out automatically, but I'm reading on the forums you have to play with that gear again to bring the shoes back out.

Any ideas which it is?

Use the wheel to get close and the brake lever for final adjustment. Tighten the wheel until the drum barely goes on, then pump the brake lever a few times. If the self-adjustment is working the lever will only come up about half-way. As you drive the car occasionally you'll notice that parking brake lever got tighter as the wheel moves a notch.

Awesome, that's exactly what I was hoping to hear, thanks @Zed Head.

Does it matter that one drum's shoes are currently further-in than the other side's since I didn't need to loosen the passenger side's shoes to get the drum off/on but I needed to loosen the drivers side's? Basically I'm asking if the drums will permanently be unevenly tight, or if the automatic adjustment system will handle tightening the drivers side only so it matches the passenger's side and if that system has an adjustment limit. As an extreme example, if the drums are pulled all the way in using the adjustment wheel, would pulling the emergency brake 100 times get the car to the same/correct shoe adjustment level as if someone followed the FSM using the method you noted (albeit just taking considerably longer by contrast)?

Also, the auto adjustment system is only calibrated using the emergency brake and not the brake pedal, right?

It will even both sides out.

It affects the adjustment of the shoes so will affect the brake pedal. Can't remember for sure but I think that you will also feel the brakes apply a little higher on the pedal after a notch gets taken up. It's one reason that seems rational for converting to disc brakes if you're in to precise brake performance.

Should emphasize though that you need to be sure the parts are clean, lubricated, and not worn, in order for the system to work correctly. You can test it with a drum off by pulling the cable by hand and watching the parts move, I think.

If I know the adjustment gear turns since I backed the pads in, does that mean the system is good? I really don't want to fight to pull the drum off again.
