A brake system for vehicle is provided to stop the vehicle even the engine stops in the driving condition by increasing the frictional force between a disc and a pad. Therefore safety of the occupant who boarding the vehicle inside is improved. A brake system for vehicle is the disk brake(100) operated by the fluid pressure and pressurizes the brake disk(110) rotated with a wheel for stopping the vehicle. Temperature is increased if it is provided with the power source inside the caliper(140) of the disk brake from the battery(B), metal(150) in which the expanded coefficient of thermal expansion is big is installed. According to the bullation of metal, in order to be reversed the master cylinder(130) in which it is provided with the piston(131) is installed in inside and outside of caliper with former. |
