You bleed the rear brakes the same way you bleed the front brakes.

Removing the master cylinder and bench bleeding the master may be what you need to do and don't let the reservoir go dry!

Can you replace brake reservoir on a vehicle?
Sure. Sometimes it's integral to the master cylinder. But some master cylinders have a separate brake fluid reservoir that is connected by either a fluid tube or fit into an "O" ring seal on the master cylinder.

If you can't find a replacement master cylinder reservoir any other place, you'll need to get one either from a dealer or a wrecking yard.

Your brakes won't release even after the parking brake is off. It is a '69 bug What can be done?
Unscrew the bleeder bolt on each brake, one at a time, and see if that allows the wheel to spin freely. If it won't, the brakes are rusted/ frozen and you'll need to replace them. If the wheels can then spin it sounds like a master cylinder issue or perhaps blocked lines. Replace the lines first because it's cheaper and should be done from time to time, then the master cylinder.
