I have a 9" rear out of a '59 Galaxie which has smaller brake shoes than the original Cougar shoes. I get on the brakes fairly hard after a 110 MPH run down the strip and braking action feels fine; no tendency to swap ends.

How did the car come through, with a SB or FE? It had KH 4 PISTON DISC on the front? 8" rear assy?

If the rear shoes are smaller (you would have to cipher swept area) it may explain the not needing a PPV. It is not supplying the braking force as OEM design. Is this a strip or street/strip car?

But then again, you have never had to dynamite the brakes if someone runs a red light in front of you on a slick road surface ...
