rear disk brakes

I know you need the E-brake connected to adjust the rear brakes from what I have heard... the question is, if the cable isn't connected, do you loose all braking in the back, or should you still have some brake? Looks like I need an adjustable prop valve too from what I can tell so far... or maybe I don't, depending on the answer to the above question.. but so far I have nothing working in the rear with the stock prop valve, and no E brake... I also wonder if the calipers are in working order too, now that I just got done typing this....
I will thank everyone in advance for their input on this... I only got  a couple things to get sorted before I can turn the key

Not sure I understand your question, so will cover the bases.

The parking brake will not affect normal braking.  Not sure about adjustments, aren't they separate?  The adj prop valve is to compensate for the MC not being sized properly.  While it is possible you won't need one, odds are you will.  Mount is somewhere easy to reach.  To test the brakes, raise the rear, have someone step on the brake pedal then try to turn a wheel.

Every parking brake I have seen has a seperate cable. That is how it is on my freinds 200 mustang gt at least.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

When I swapped mine, I couldnt get the rear to push much fluid when bleeding. (Stock Prop valve).  I undid the bleeder valves all the way and pushed the brake pedal, thought maybe the line or bleeder valve was plugged.  It moved a little more fluid after that, but the brakes still felt weak in the driveway, havent driven it on the street yet.  I may try a stock TC prop valve, I dont know if it is a direct bolt in???

I got the same problem. Very little fluid, and no brake in the rear. I'll fiddle with it again later on

I think with rear discs one needs a master with a bigger bore, in order to push more fluid.

daminc,

Still working on this,

I got the parking brake lines installed.  The Ebrake pedal is firm and tight, but it just insnt stopping the car much.  Im not sure what to expect when you hit the Ebrake when driving.  Should it lock the tires up, or just slow it??

I know on my Mustang with drum brakes, it would lock the tires up easily.
