1928 Model A AR Brakes

[upd8922]

I own a 1928 Model A Ford Leatherback. I'm kinda restoring it a little bit at a time. My current project is the brake system. I had the liners replaced, the Front brake pins replaced. Rear brake liners replaced along with some pins and clevis replaced. During this venture we noticed that I have a AR model due to the brake arm levers and the plate on the left side where the original e-brake arm was. Anyways, me and my mechanic just can't get the car to stop properly. I know that they are mechanical brakes and really don't stop well, but it should stop than they are. I recently noticed some play where the equalizer shift goes into brake levers. So I had the levers fixed by having them machined and drilled for a tighter fit with the equalizer shaft. Any suggestions that could help me I would accept.
