Brake device and vehicle having the same

A brake device, comprising:

• a motor unit;
• a cylinder unit having a plurality of pistons configured to be propelled by the motor unit;
• a brake pad unit connected to and propelled by the plurality of pistons;
• and
• a caliper body having the cylinder unit seated thereon, wherein:
• the cylinder unit has a conversion assembly configured to covert a rotational motion of the motor unit into linear motions of the plurality of pistons, the conversion assembly being a single unit irrespective of a number of the plurality of pistons,
• the brake pad unit is non-hydraulically operated, and
• the motor unit is located in a center region of the caliper body.

A brake device, comprising:

• a motor unit operating by an electrical signal;
• a cylinder unit having a plurality of pistons propelled by the motor unit;
• a brake pad unit connected to and propelled by the plurality of pistons;
• and
• a caliper body having the cylinder unit seated thereon and configured to guide the brake pad unit, wherein:
• the cylinder unit comprises a conversion assembly configured to convert a rotational motion of the motor unit into a linear motion,
