A mechanical type disc brake for bicycle mainly includes a housing, a mounting bracket for connecting the housing to a fork of the bicycle, a pull bar pivotally connected to an outer side of the housing, an actuating rod extended into the housing via the pull bar, and a toggle mechanism, two sliders, two brake linings, and a restoring element separately mounted in a locating space in the house at predetermined positions. When the pull bar is pulled, the actuating rod is caused to vertically act on the toggle mechanism for two actuating blocks thereof to move outward and push the sliders and the brake linings to create a brake effect. Contact surfaces between the actuating blocks of the toggle mechanism and the sliders are cambered surfaces to avoid an overly large frictional force between the brake linings and brake discs that would result in a brake dragging.
