I don't know guys, this issue with the brakes now has me paranoid.  I'm second guessing the push rod length being the culprit.  Am I using the correct MC for my disc/disc application?  Over the last couple days I read somewhere that the disc/drum MC's have some type of internal valve that bleeds pressure from the rears more slowly.   Is this a function of the PB6.1 iron master cylinder that I have installed? This, in combination of the description I see in MS's web store has got me concerned.  I just want to make sure I have the correct components before I move on to something else here with the car.

Well everyone, Since my last post, work on the 65 has been sporadic with work, other projects and a baby but, progress none the less.  I come to you guys with an issue that has us stumped at the moment.

The car is ready for a few final touches of body work before we spray it, so yesterday I fired it up and decided to drive it the mile from my dads place to my house so I can put an hour on it in the evenings, until its ready to paint. This was basically the first time the car has been out of the garage on its own power, ever, so I took it up and down his driveway, about 400 foot driveway, a dozen times or so, making sure it stops, no crazy issues, etc.  All systems were a go, it was running good, stopping good, etc.  We make the decision to get on the road.  I get a quarter mile down the road and go to shift into 3rd or 4th gear and the car feels like its dragging.  Soon as I push the clutch in to shift it was like the brakes were on.  I get it turned around and limp back to my dads, and get it up to the house.  Brake pedal is hard as a rock.  So, we're kind of shocked as to whats going on.  Let the car sit for 20 minutes or so while we're discussing what went on.  We can see that the rear tires are just loaded with road tar, like they were hanging up/spinning or a combination of the two.  Pull the car into the garage, now the brakes feel free and the car rolls right in.  I block it up expecting there to be an issue with one of the calipers, everything turns freely.

Now, just so we're on the same page, the set up on this car consists of grenada front spindles/disc brakes, Versailles 9 inch rear with a traction lock unit with 3.55 gears, with disc brakes also.  I had lucked out years ago when we bought the rear end and ended up getting all of the components including the e brake levers etc.  We were able to hook all of that up and it is functional.  I had purchased and installed the PB6.1 master cylinder and PV-70 proportioning valve from Mustang S

Thanks for the stock 65 MC pushrod. Much appreciated.

Thanks for the quick response gentlemen.  Steve, as far as the lower ball joints, we used the 65 mustang lower control arm/ball joint.  It bolted right up without issue.  We were under the impression that this did not need to be changed out when making the granada swap. (we also did the shelby drop with the upper control arm) 

We havent hooked the tie rod ends( and the remainder of the steering) up yet.  I believe what we currently have are the granada tie rod ends. We were going to move to steering next (im buying a flaming river box/shaft etc.). Am I missing something here with the set up the way it is now?

Im going to discuss the information with the Dad after work today and will get back to you (Steve) with some info about getting some parts ordered.

Thanks again, the excitement level is increasing with every new change to the car.  We were just talking the other day that we thought it wouldnt have come this far.I have a bunch of pics of the progress so far, but I had uploaded them to another website forum (I bought a couple fiberglass parts from).  I dont want to put their name in here unless Im authorized to do so, if you guys were curious about the car and wanted to see sme pictures. Let me know and I can put a link in a reply.  I dont want to take business away from Steve(although I dont think they sell the same type of stuff), but it would take forever for me to upload the pics to these forums with the connection we have at home.
