Hello, I am new to this forum but I have spent the last 1/2 hour searching for a possible idea on my brake problem with no luck. Please forgive the length of my post, I will try to keep it to the point and somewhat short. I recently purchased my dream car. A 1969 Mercury Cougar xr-7 convertible. The car has been sitting for the last 14 years so one of the first things we needed to do was to revamp the brake system (the fluid was terribly contaminated, it had a grey-brown ewwwww color). I have replaced all of the drum components (wheel cylinders, springs, etc), all of the lines have been replaced with new stainless steel lines, I have replaced the calipers, had the rotors turned, replaced the master cylinder *(yes I did bench bleed it) and have a new brake booster. The first time we bled the brake system, it felt great, solid and firm for the rear brakes, but as soon as we moved to the right front, it got spongy and has not worked right since. I was pretty sure it was either the distribution block or the proportioning valve. So, I have now torn down and cleaned them, then seem to move freely. The problem I have is the top half of the brakes are weak./spongy, and the only brake that seems to be working is the right rear. Any ideas on what would make the front disc brakes not work? Is it that my proportioning valve is just toast? Thank you in advance. I am at my wits end with this project.

How do you get to the front running lights or side lights of this truck. It is burnt out and dont want a ticket. Thanks
