HCB3200
So do you mean the port at the back when mounted on the frame goes to the back and front to the front. That is how I set it up. The port closest to the push rod (which faces front) goes to the front and the one away from the push rod goes to the back.
If I pump the brake comes up some, maybe half way, but never really gets hard. I drove it and it was scary. The only thing that saved me is the low gear ratio in the read end. The truck is slow
The 2 chambers are the same size. If you see the pics I attached, the description states is is for a drum/drum system for as 47 to 54 Chevy truck,
I am bummed I drive this truck all the time and I can’t seem to see my way to getting this fixed. I spoke to the company and they said to send the MC back and they will send a new one. Im not sure that is the problem.
I am sucking air in somewhere but for the life of me I can figure it out. never had an issue like this before.
