A brake system (1) for use with a wheeled device, such as a wheeled person transportation device, such as a wheelchair. The brake system (1) comprises a handle (2) comprising a first portion (3) and a second portion (4), wherein the first portion is moveably coupled to the second portion； a carrier (9) comprising an internal cavity (11)； a brake actuator (13) for actuating a brake, the brake actuator being arranged within the internal cavity； brake actuator biasing means (17) for applying a biasing force to the brake actuator for biasing the brake actuator to a brake-engaged position； and force-transfer means coupled to the first portion and to the brake actuator such that movement of the first portion towards the second portion causes the brake actuator to move along the internal cavity of the carrier against the biasing force to a brake-disengaged position.
