[700rpm]

Brake work is not an essay question or a guessing game. Get ahold of a good book, like Les Andrews's red book, and read how to do it properly. Get local experienced Model A help if you can. You are dealing with literally life and death here.

Oh, and always block your wheels and have a secondary support system so if the jacks or stands slip you don't get squashed. I am especially careful when I have all four wheels off the ground (which I try to avoid).
