How do you change the drum brakes on a 1992 Buick Century?

Answer 1

The question you ask is too involved for a proper answer. You may want to go to a car parts store, or book store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.

The problem is the number of small pieces of hardware that must be put back together just so. These include, besides the brake shoes: hold-down springs (2), return springs (2), star adjuster, spring for the star adjuster, wheel cylinder if removed, backing plate if removed, brake line connection if removed, self-adjuster lever, self-adjuster spring, self-adjuster connecting arm, emergency brake cable, emergency brake lever. And of course the drum, which may be rusted on. Even with a repair manual, if you have a digital camera, it's best to take a picture or two of it all before you disassemble it, to consult in reassembly.
