If these two (2) separate means of applying brakes are connected in any way, they shall be so constructed that failure of any one (1) part of the operating mechanism shall not leave the motor vehicle without brakes on at least two (2) wheels.
- (b) Every motorcycle, and bicycle with motor attached, when operated upon a highway shall be equipped with at least one (1) brake, which may be operated by hand or foot.

- (1) Every trailer or semitrailer of a gross weight of three thousand pounds (3,000 lbs.) or more when operated upon a highway shall be equipped with brakes adequate to control the movement of and to stop and to hold the vehicle and so designed as to be applied by the driver of the towing motor vehicle from its cab, and the brakes shall be so designed and connected that in case of an accidental breakaway of the towed vehicle, the brakes shall be automatically applied.
