Im going to convert my 74 to front disc brakes. I plan on using a nonpower master cyl. will the push rod from my drum brake master work with the non power disc brake master? Also where do I get a proportioning valve for this new set up?
The good news is manual disk brakes were available on 74s. You will need a master cylinder for a 74 manual disk brakes which should be available at most parts stores. Just make sure it has the same depth as your old master cylinder. They should be the same.
You will have to get the proportioning valve from the junk yard or source it from Stainless Steel Brakes are similar aftermarket supplier.
