Waste of time and money. Drum brakes have too many inherent problems, and poor capacity to stop, especially repeatedly and high speed. They get hot and glaze. A power booster will make them easier to push, but when they exceed their capacity to work, all the brake pressure you can put on them will not make the car stop ! Your money and effory would be much better spent on a manual disc conversion Original is nice, but a car always looks bad with the front end smashed from a couldn't stop !
