Quote: I had exactly the same issue with my '70 Mustang (disc front brakes, but using this to make a point). No matter what I did, I couldn't get that car to lock the fronts. EVERYTHING was new. I even got very expensive cold stopper pads from Ca. In the end I went to AutoZone and got a set of $18 pads. Bang! Fixed. It may be as simple as brake shoe compound or having the drums turned.
Last night I got to thinking & was wondering if that is it. Not enough friction on tthe shoes
My guess is that's what it is. I really don't think it's the master cylinder. The OP hasn't answered yet if the drums were turned. If they are glazed, it could cause this, even with new shoes.
