Abstract
A castor with separate brake device and brake release device is provided with a shell, a brake piece, a brake unit and a brake-release unit. The brake unit and the brake-release unit are two separate members, while they are interactively linked by a push portion and the notch portion, so as to ensure the accuracy of the brake operation. Whenever the castor is in a brake-activated status or brake-deactivated status, the brake pedal and the brake-release pedal pivot in opposite direction to present different angles, which makes it easier for the user to see the status of the castor (in brake position or non-brake position), and prevents confusion or accidental operation.
