Abstract
A disc brake comprises a caliper mounted slideably relative to the axis of the rotating disc, on a fixed support by way of an axial column, two friction members mounted on carrier plates anchored and axially slideable inside an opening in the fixed support so as to come into frictional engagement with the opposing sides of the disc when a brake motor is operated, and a locking element extending axially between at least one opening formed in the caliper and at least one opening formed in the fixed support so as to help guide the caliper on the fixed support and prevent it pivoting about the column when it assumes its normal operating position. A spring is mounted on the caliper on the side located circumferentially at a distance from the axial column, the mounting portion being elastically mounted inside at least one opening provided in the caliper for the locking element to pass through, the mounting portion surrounding substantially the part of the locking element passing through said opening, the rigid working portion being capable of biasing elastically the friction-member carrier plates substantially radially towards the axis of the disc.
