On an Austin Seven I would say brake lining wear is the least of your problems.

At the time I was complaining of instability under heavy braking. (This on my race car). Wear didn’t come into it. I fixed it in the end by changing the offset of the front wheels.

Increasing it or reducing it?

That would be telling.
Oh, ok. It doesn’t really matter. What I was trying to do was reduce the steering couple induced by brake force variation - wide wheels move the tread centre away from the king pin axis and this causes a turning moment on the wheels. Wider wheels increased the ground level offset. What I had to do was move the wheels inboard by increasing the wheel offset.
