Reference: AQA
The kinetic energy store of the vehicle decreases because its speed falls, and the energy is transferred to the thermal energy store of the brakes and surroundings.
When a moving object slows down, its kinetic energy decreases and is transferred to other stores, such as the thermal store of the brakes via mechanical work.
Energy can move between stores when the system changes, and any difference in mechanical energy is transfer to a thermal store by heating.
