Why An Electric Car''s Brakes Work Differently Than A Gas Car''s,

When you step on the brake pedal, the brake pads make contact with the brake rotors (or drums), and the resulting friction creates heat which is then dissipated to the surrounding air. Heat is another form of energy, so what your brakes are doing is converting the energy of motion, i.e. the kinetic energy, into heat energy.
