Progress has been S L O W, keep thinking things will go faster, but they don't.
The master cyl, proportioning valve, brake lines, steering, and driver's side suspension and brakes are in place with most everything ready to be torqued.
The disk brake swap had some surprise issues that I think are now all under control. IIRC, disk brakes were not available thru '73, 10" front disks were an option in '74, and 11" (same as Granada) disks were standard for '75-'77. Most reports of swapping the later disk brakes onto earlier cars are described as bolt ons. That's mostly true but a lot of guys cheat

and use drum/drum stuff on the disk/drum conversion. Me, I swap EVERYTHING 'cause I don't know the consequences of the mis-matched parts.
Some of the differences are:
. Length of the rod between master cyl and brake pedal. Manual disk brake rod is about 1/4" shorter which will change the height of the brake pedal about an inch or more.
. Master Cyl piston sizes and tube nuts. There are FOUR different tube nut sizes (hex and threads), all for 3/16" tube. Ford changes them all around to AVOID swapping parts. Try to find those larger ones if you need to make some custom lines.
. Proportioning valve is rotated 90 degrees changing the geometry for all five tube connections.
. While the drum/drum proportioning valve was mounted directly on the fender apron, the disk/drum valve seems happier mounted about 1.25" off the apron.
. Brackets that hold the rubber-to-steel connectors mount about 10" farther forward. The brackes mount to nuts welded INSIDE the frame rail.
Thought I would cope with all that by ordering all new/rebuilt master cyl, pre-bent lines for the front brakes, and rubber lines for the '76 disk brake cars. But those short lines with the complex bends that go between the master cyl and the proportioning valve weren't right. Fortunately, the ones from the donor car were still good so those were used. To hold the proportioning valve off the apron, I made these spacers by welding 5/16" nuts to both ends on a 3/4" piece of 3/8" pipe. One end screws on the studs on the valve and the other end is fastened by bolts thru the apron. Notice the extra marks and one errant little hole in the apron.
So, what to do about the missing nuts that should be welded to the inside of the frame rails? Thought about big hex-head metal screws but rejected that idea because all the flexing might loosen a metal screw allowing the steel line to move, bend and break. Thought about welding the brackets to the frame rails but the driver side bracket is about 1.5" from the fuel line. Decided to drill holes thru the frame rails and fasten the brackets with 5/16X3" bolts.
I've never seen disk brake assemblies like these. I expect there are a lot of failures because the caliper doesn't move. To fasten the caliper to its mount, a long, flat, heavy spring is POUNDED (well, maybe tapped) into place.
When its assembled the caliper will NOT slide by pushing or pulling on it. Doesn't seem right to me but multiple sources say it should be very tight when assembled. I'll check on it after a few miles.
The tube nut on the line going to the rear brakes was bigger for the drum/drum brake proportioning valve. After trying unsuccessfully to find fittings to make the transition, I cut the fitting off the line going to the back, cut another line with the right fitting for the valve, and used a 3/16" union to join the two lines. The union is visible in the above picture of the installed proportioning valve.
Should go faster now, right??
