I was too broke for a proper fix so a friend welded a glob of metal to the worn end of the shoe and we ground it flat to make a bigger surface for the brake cylinder piston to hit, then soaked the brake shoe in gas and lit it to burn off the brake fluid! Insane when I think back on it, but probably not the dumbest thing I did in my teenage years, and those brakes lasted several more years!
It had some crazy mechanical issues. At one point it stumbled and stalled because the carburetor had come loose from the intake manifold and I had to tighten it back down! Another time, my brother was driving it and the brakes failed. Somehow the end of the brake shoe that meets the brake cylinder piston had become worn on one side, causing the piston to slip off the end of the shoe when the brakes were applied, losing braking and squirting fluid all over.
