so I installed a manual 4 wheel disc conversion from the right stuff detailing on my 65 Plymouth a year or 3 ago and the car works great and the braking has improved dramatically but now that im playing with the engine and getting more and more power I feel the brakes are not as good as they should be. Im looking over the install that I did and I've run into a potential problem...when I first put the kit on I went from a single master cylinder to a dual master cylinder so I installed this distribution block https://www.getdiscbrakes.com/rsbb123 the only problem is it has 6 ports on it...1 inlet for the front and 2 outlets for the front which is great but then it has one inlet for the rear and 2 outlets which I manufactured a plug for one back in the day cause I only have one line to the back of the car which flows through an adjustable proportioning valve then it meets the factor splitter on the rear end....so my question is why is there the extra port? am I crazy to think there should only be 5 ports total on the block? and do you guys have an suggestions ...I did some testing and I can get the fronts to lock up with hard braking but not the rear no matter where I put the proportioning valve setting...any advice here would be great
 
An extra port may be for a balance switch (warning light) or an auxiliary brake light switch if it's a universal block.

Checking pressure is about the only way I know to properly diagnose rear discs.
 
This is how I have my dual master cylinder/four drum block. Only five ports.
