Actually, you only need the disc brake proportioning valve if you have power brakes. The purpose of the proportioning valve is to reduce REAR wheel lock-up. In fact, the 1974 Maverick with optional disc brakes used the SAME proportioning valve as the drum brake setup...
: : I too, had this problem when I swapped discs into my '73. If you have access to a disc brake car, that part of the fuel line is removable. It has a connection under the driver's floor pan and can be bolted right into your Mav. As for the power vs. manual question, they do not HAVE to be power assisted (my '74 isn't), but you MUST use a mstr cyl for a disc brake car!! (I also suggest getting the proportioning valve from the 'donor' car). Hope this helps.
: : : I have a 73 grabber that Im fixing up. I Have replaced all of the front suspenison. I have installed the spindles,rotors,calipers from a 76 mav.I had to remount the brake lines and now i believe the gas line is not going to work.Is this true?Also do the disc have to be power?I do not have a brake booster if they dont have to be power can i use the master cyl. from the old drum brakes?
: >>> I swapped '77 discs into my '70 and it was a straight bolt-in. TB is right - you need to use the disc master cylnder & proportioning valve. They work fine w/o the booster, but do require a little leg muscle. The brake feel is a lot better,though. You won't belive the difference in stopping! I can't address the fuel line issue - my car is a 6cyl & I didn't have to do anything to the fuel system.
