[BRENT in 10-uh-C]

In my opinion you either need to find an experienced mentor that KNOWS how to correctly work on Model-A brakes, -or you need to find a professional that is experienced with these. In this day and time, you don't need to take a chance on poor-performing brakes. The mechanical brakes on your car should be able to make nine (9) 40mph to 0mph panic stops in a row, -and on the 10th time they should be able to slide all 4 wheels at 40mph with the pedal no less that a ¼ way off the floor. If they won't do that, then they need work.
