What's so bad about drum brakes on cars?

Another important factor is “bang for the buck”. Those big drums come with a great weight penalty for the amount of performance they offer. Additionally, IME, braking response/feedback is pretty poor from a set of 4x drums. It’s like just pushing harder on a wall… not much sensitivity.

Though you didn’t ask, a plus to drums is simplicity of the parking brake. They only need a cable and ratchet attached to the shoes to hold fast. My rear disc brake car requires a separate parking brake circuit.

I think a Corolla with drums would be just fine and would barely consider them a handicap on that car. If it’s only the rear brakes that are drums, you’ll never notice. Until you have to work on them, ha!
