I recently replaced  all brake shoes, and wheel cylinders on my 56 Victoria with the original single master cylinder and drum brakes. I adjusted each wheel by backing off each star adjuster 9 clicks after the wheel  would not spin by hand, leaving no drag at all. A test drive revealed a pull to the right on braking. I then adjusted the left front out by 4 clicks and that seemed to even it out.  My question is: Does one need to break in new brake shoes before you can lock up the brakes on a hard stop. The factory service manual advises strongly not to do severe braking for the first 100 miles but I feel like I have to push rather hard on the pedal to stop the car quickly and would have to nearly stand on the brake pedal to lock them up. By the way, I did not have the drums turned as they did not appear to be badly scored. I have more that half a pedal apon engagement and 2 quick pumps gives a little more.
