I have an original cap and after bleeding the brakes and heading out for a tour I noticed fluid on the bottom side of my hood (I cleaned it off right away) and the top of the cap.  Will the cap go bad? What is the purpose of the little hole at the top of the cap? Will this be sucking air into the system?

  I had done the bleeding because I had a faulty crimp on a braided line that was pushing fluid between the clear plastic sheath and the steel braid on the back.  While at it I decided to switch my front pads to Porterfields.  My pedal now seems to have way too much initial travel and although we thought we had gotten all of the air out, we must have air in the system.

I have SAAC rear Wilwoods and the stock Girlings with Porterfields, no proportion valve.  I have never been able to get them to lock up, tonight it seemed as one rear locked up first after repeated hard braking.

Any ideas or help is appreciated.

I went through this same issue with the shuttle valve when bleeding my brakes. I also had the Ford part # but could not find a direct replacement (most that look similar are for disc/drum cars). I also purchased the "rebuild kit" from MuscleCar Research which did not solve the problem. I even sent my shuttle valve to the owner of MuscleCar Research which he rebuilt for a fee and it still didn't work correctly. After talking to Scott Bell of SACC Restorations, I removed the shuttle valve and replaced it with a T - Problem fixed and the only downside is i won't get a light if brake pressure is low but if that happens you'll figure it out quickly. Scott is very knowledgeable and helpful so if you need to buy anything for Pantera brakes, he'd be my first call

Don't waste your time attempting to rebuild with the MuscleCar Research kit. For the same money and less aggravation, you can plumb in the T and do away with the shuttle valve. You will have to flare one or two lines but in the end, that is a lot easier and faster than messing with the shuttle valve.  Here is a pic of the set up with the T replacing the shuttle valve. I have since fabricated a small aluminum bracket that bolts to the trunk floor in the original holes and is threaded so the T can be screwed down to the aluminum

when i was having my "issues" Scott Bell of SACC Restorations was kind enough to provide a list of the items needed to convert to the T.  Here is the list: 

Brass Union - 5/16" Line - Both Sides Female SAE 1/2" X 20 Thread - Inverted Flare - Pack of 10

 Earl's 972055ERL Brake Adapter

 Brake Light Switch with 3/8 Inch IFM Adapter Fitting

https://www.amazon.com/gp/prod...;smid=A1FJ1WMPKJVUMQ

This is all you need along with a slight amount of bending the existing brake lines and maybe one or two new flares
