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.

The plastic cylindrical member may engage with a cylindrical hole provided in the supportive arm. The upper end of the pivotally connective member may engage with a first connective hole and the lower end of the pivotally connective member may engage with a second connective hole of the roller. Thanks to presence of the plastic cylindrical member, when the pivotally connective member rotates and causes the roller to rotate with it, the supportive arm doesn't have any contact with the pivotally connective member and thus noisy friction and impacts between them as in the prior art may be avoided. Therefore, the plastic cylindrical member is difficult to wear out as the pivotally connective member rotates.
