Hi, I am considering a power brake upgrade for my 1965 Ranchero. It has been upgraded with Granada spindles, front disc brakes and dual master cylinders. Has anyone used a Master Power Brakes kit? They seem to have a complete and reputable kit.
In the Technical Section there is a section on power brake boosters. It seemed to me that because of space issues that a lot of the boosters are too small to work well, (seen some complaints). You may have a similar issue in a '65, don't really know. The original brake booster on a '57 was under the dash!. I went with a modern Hydro-Boost setup but you need power steering for that...
Welcome to the forum!
Tomsclassics shows a booster but with the single jar. https://ebay.us/m/PRmA5f
I have two cars with the original single jar. No issues. Adding power would just make it easier to press.
