Re: '70 Drum Brakes; when is rebuilding necessary? what should be done to optimize pe
I'm assuming you are talking about front drum brakes. To optimize performance, take off the front drums and install disk brakes.
If you are dead set on the drums, I would replace the shoes, replace the hardware kit, replace the wheel cylinder, and have the drums turned.
While you are in there this far I'd inspect and replace if necessary the wheel bearings.
Then I would put it all back together and make sure ALL the old brake fluid is flushed out.
After everything is all bled, adjust them to spec.
Then do the rears. New hardware, new shoes, turns drums, replace wheel cylinders, and make sure all the old brake fluid is flushed out. Button it up and adjust the shoes to spec.
