New master cylinder blues!!

[GMtrucknut!!]

I recently finished installing my TCI mustang II frontend in my 55 series II. While doing this I also decided to upgrade to power brakes so I ordered a frame mounted CPP master cylinder kit complete after meticulously bending all my brake lines to keep it all looking great I went to bleed the system tonight and low and behold brake fluid gushed from the proportioning valve as I checked the lines to be sure I didn't leave one loose it became apparent that the valve itself was leaking. I have called CPP and they have told me that they would send a new valve to me . I guess we will find out how good their customer service is!
