I need to do some work on my rear brakes. They are losing fluid, and the rear has gone from being sticky after sitting a few weeks between driving to completely grabbing/mostly engaged when driving forwards and only mildly grabbing when in reverse the last month or two. I haven't checked which side it is, and due to parking on gravel, have not noticed fluid anywhere in particular. I also just assume that whatever I do to one side, I'll do to the other.
I haven't torn into it yet, but I'd like to order my parts and just dig in once. I'm assuming that I'm getting fluid out of the wheel cylinders and onto the friction material, hence the grabbing. New wheel cylinders, new shoes (surely fluid has soaked them?).
New springs and hardware kit is cheap, so I plan to order that too.
I see that the self adjuster kit is separate and more expensive than nearly anything else. I don't know that I'm having issues with the adjusters (am I?), can I safely skip that unless I see some obvious issues when I pull them off?
What else should I do while I'm there? I'm not made of money, and I'm not having any other particular issues, but I haven't messed with drum brakes that much and this is the first heavier truck I've had.
Also, how do I know which brakes I have (it looks like there's 13", 11" and 11.15"?) I have code C6P, which shows 8600 GVWR on a codes list found online. Does that indicate which brakes I have?
Thanks all. And for reference, it is a stock '87 3/4T Suburban with a little over 110k original miles. No real idea on previous maintenance other than it was a university owned vehicle originally, then bought at auction by the previous owner and used as a hunting truck, generally take care of though. Now the truck gets many more miles flat towed behind my RV than under it's own power, but hunting season is coming and I need it back in shape.
