So, this is a beautiful thing:
UNLESS...&#*&%#(*Q%&#)(Q...I measured three times, using the old cable & a string, and still came up short!
So two options - order another cable or make the rod longer...went for Option B...
So this:
Turns into this:
Here's the assembly installed:
I used a length of steel rod, threaded it and an NF all-thread coupler with lock nuts. So far so good; the cable, being new, stretched some but it still woulda been short.
My original plan was to use the cables that came with the rear disc kit, but the cable intended to reach the p-brake lever was woefully short. I looked at available options for swedging my own ends on a cable, and even ordered stainless stops. Turns out it's true that any suitable tool is gonna cost at least a few hundred bucks.
I've got a Mt. Everest steep-ass driveway and thinking about one of the kids walking behind the Comet...couldn't half-ass it. Glad I didn't! Turns out a cable ain't that much $$. Inline Tube doesn't make custom cables any more, but I found an outfit called Control Cables...$65 bucks + S&H...not bad!! They made the cable sheaths with the right ends for the p-brakes on the Caddy calipers on one side and to fit the original brackets on the other side.
After letting the cable sit under tension overnight, I used a dial-caliper to adjust until just before the levers started to move, and worked the p-brake about 30-40 times. Pedal is better now so I gotta get it off dollies and drive it!!
We'll see if the under-dash assembly has the ratio to put enough tension on the p-brakes!!
