In preparation for the GMC Midwest June rally, I want to dig back into my rear brakes to try and improve performance. I'd replaced shoes and springs last summer and have less than 50 miles on them. It seems to take a lot of effort on the brake pedal to come to a stop. I decided to put in all new wheel cylinders with 1 1/16" on middle bogey and 15/16" on rear. Jacked up the rear yesterday just to get a look and was surprised to find that each wheel takes a significant effort to turn by hand.
Are the brake drums supposed to be that difficult to turn when properly adjusted? I'm certain I set the adjustment last year according to the FSM, which states to back off 30 clicks once the shoes drag on the drum.
The rear brake lines were replaced roughly 10-15 years ago with units from Cinnabar. Could those have failed?
I had adjusted the parking break at that time as well, need to check it is properly releasing.
Any help much appreciated!
