Default "Tweety Bird" Gets Disc Brakes & More

Today the work on putting in a new dual MC and dual 8" power booster (both chromed from Old Irish Dave-OID for about $20 more over the regular price) started. My mechanic buddy of many years is doing the work for me. The plan was to get the MC and booster in under the hood, do the new brake lines with S.U.R.&R EZ Bend 3/16" tubing that I bought from Dave and do the disk brakes. I am using the Scarebird mounting pieces. Howard suggested that we do the MC and booster first because that was going to be the hardest part to do and would take some time to get it right.

Right off the bat, he ran into a problem of getting the lower panel off the drivers side to get to the KH unit under the dash. It took awhile, but he got it off. Then he ran into a problem of detaching the clevis from the KH unit to the old MC. He could not get that apart because the bolt came up against the brake pedal. That delayed us for quite some time, but he finally was able to detach it after Howard told us how he got his lose. As it turns out, Dave said that had we removed the old MC first, it probably would have gone better and faster. By this time, we were about 2-3 hours behind our schedule.

After we got the old MC out, he put in the new chromed mounting bracket that Howard Prout made for us, along with a rubber seal against the firewall, and a chromed mounting plate over it. It took awhile to get the new "hockey stick" that Howard made for himself (which is working great for him the last year or so) and myself, to attach to the KH clevis, but he got it. Like Howard, I had decided to leave the KH unit in place and hooked up. Leaving it has not caused any problems for Howard.

After that, he made some alignment adjustments on the mounting bracket to make sure we had a smooth movement of the hockey stick between the bracket and through the hole in the firewall and that went well. We did some checking of the brake pedal to make sure we had good action there and we did. Nothing is getting hung up. He tightened down the washers and nuts on the mounting bracket and bolted the power booster booster to it. He mounted the MC to the booster, along with the chromed mounting bracket Howard made for us to hang the Combination valve on.

Then we did some checking on the adjustment of the machine bolt that sticks out of the MC into the power booster. We found it was not long enough and by running it all the way out, it was still not long enough. Then off I went to Home Depot to get a couple of longer machine bolts, something about 1/2" and 3/4" longer than the one that came with the unit. As I recall, we used the one that was 3/4" of an inch longer, adjusted it and got a good setting on it. That machine bolt we used is a Metric hex bolt M6-1.0 x 30MM. So we bolted the two units together and hung the Combo valve on the mounting bracket to see what it was going to look like. It sits lower than the air cleaner and is also level. We did not have to use any washers to level it.

It this point it was long into the afternoon and we had thought that we would have been doing the disc brake conversion by then, and would have been well into completing that. But earlier delays changed those plans. My buddy had received a phone call and had to leave to move some engines to another location. Since we were at a point where it was safe to stop and move the car, we decided to continue this project early in the morning and let him take care of other business.

Very early in the morning we will start again and he will start flaring and bending tubing to install on the MC and Combo valves. We will only be doing the front brakes and lines. The lines to the rear were recently replaced last year. He will do bench bleeding and then we will hook everything up and see how it comes out. Once he is finished in the engine bay, he will start working on the disc brake system. I drove the car back into the garage for the night, without any brakes to speak of, using the emergency brake to stop. So tomorrow, hopefully, things will go much better because, as Howard said, we have the hard part behind us, getting the old MC out, the new equipment in and set up. After the new brake lines are in and that is done, he figures it will only take a couple of hours to do the disc brakes.

I need to do some more wrapping or covering of wiring before we finish. Also, although the AC hoses stuck up quite a bit, when the booster was put in place, it pushed them down and out of the way. The bottom of the chromed mounting bracket just barely clears the steering wheel shaft, but it does. There is also several inches of spacing between the bottom of the power booster and the piece that sticks out of the steering column that connects to the tranny. Here are some pix that I took this morning and afternoon of what we have accomplished so far. Including one of everything sitting on my couch ready to be put to use!
