I'm trying to get my 73 Chally out of a 10 year hibernation and the brakes have zero response. So I'm leaning heavy on the Master Cylinder as the culprit. I'm probably going to order the Year One conversion kit DSR70 which is the both the booster and cylinder. Has anyone had luck with this? Or any better recommendations or advise, does it provide more power than stock? I also want to refurbish the old equipment at my convenience if it's worth it. This kit is $500, the electric powered one looks awesome but unfortunately money is a factor.
