A brake system,of the invention comprises a brake pedal,a booster,which boosts the input force applied by the brake pedal,and outputs the boosted force, a travel amplifying mechanism,which amplifies the travel of an output shaft of the booster,and outputs the amplified travel, a master cylinder,which develops master cylinder pressure when the output from the travel amplifying mechanism,is applied to the master cylinders,and wheel cyclinders,which develop braking forces when the master cyclinder pressure is introduced into the wheel cyclinders. By the travel amplifying mechanism,the travel of the brake pedal,in the initial stage of operation is amplified by the travel amplifying mechanism and is then transmitted to the master cylinder,whereby the idle stroke of the operating member caused by various idle portions in stroke in the brake system can be effectively shortened.
