Gonna rebuild the rear drum brakes on my ‘67 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Does anyone have a link to a DIY regarding rear drum brake rebuilding for my ‘67 GMC or other compatible year (and/or particular things to watch for?). I rebuilt the front brakes a while back with no problems, but I feel better if I have a reliable go-by handy….

Also, should I rebuild the master brake cylinder while I’m at it or wait until it starts misbehaving?

Thanks in advance for any and all info! I love this board!!!

Make sure you do only one side at a time. That way you can get an idea of how to reassemble if you are uncertain, or take a pic of it prior to disassembly. Make sure the shoe with the shorter lining material goes towards the front. Always preferably replace or rebuild the wheel cylinders, since they fail if they set just a few months, and ensure the bleeder screw can loosen. Make sure the self adjuster is free and apply some high temp anti-seize to the threads. Use high temp anti-seize on the drum to hub mating surfaces to ensure the drum comes off the next time you need to service the brakes. When you have the shoes adjusted properly on both LH and RH, adjust the parking brake.
