1. A brake shoe assembly for a vehicle comprising:

  • a brake lining having a predetermined thickness for gradually wearing away as the brake shoe assembly brakes the vehicle; and

    a sensor having a pair of spaced electrical conductors and an electrical resistance for indicating said thickness of said brake lining located across said pair of spaced conductors, said pair of spaced conductors being cohered to a subtrate;

    said sensor positioned to wear away concurrently with said brake lining thereby continuously changing said electrical resistance to an infinite number of values across said pair of spaced conductors.
