I am getting ready to put new rear rotors on my truck, probably in a couple of weeks. I have been told that when I do the job that I should adjust the e-brake. my question is, How do you adjust the e-brake exactly and is it adjusted on both rear wheels or just one? Thanks guys.
It adjusted on both rear wheels. There is a rubber plug with a star wheel inside you rotate with a flat screw driver or a brake adjuster tool. It's not very accessible, but can be done. I went to back mine off a couple weeks ago. Put the rubber plug in the left side, and it went all the way in. I had to take the drum off to get it out, good thing though, cause both linings were laying in there inside the drum. I put new linings on both sides, truck is no longer sluggish, I guess they were putting a drag on there most of the time when they'd get caught in there together. When I put the new ones on, I left them backed off most of the way. I don't use them, but they will still hold if I need them. They were still almost in contact with the drum when they were all the way loose. What I mean, I had to work the drums some to get them over the linings when they were all the way backed off. Probably could have tightened them a bit, but as I said, I never use it so I left them alone.
Most drum brakes are self adjusting. Ours are actually "parking" brakes, and are only (usually) engaged manually at a stop. That star wheel is for getting the shoe adjustment close to correct (and for backing the shoes of for hub removal). The way we would complete the adjustment on the old drum brakes was to roll slowly backwards and apply the brakes firmly. That would cause the shoes to seat properly and you were done. All of us old guys can remember the excitement after going through water and trying to stop with all drum brakes.
I've heard of several people having the drum/parking brakes on our model truck siezing. Likely from lack of use, same as 4x4 shift motors seldom being used.
