ABSTRACT:
An automatic gap adjustment device for a disc brake comprising a cup-shaped piston which has a bottom in the fore end thereof and is arranged to move within a cylinder of a caliper, a sleeve which is axially disposed within the piston and is arranged to be carried by the piston when the piston is moved forward by the action of hydraulic pressure, and a spindle which is in screwed engagement with the piston and is arranged to rotate and screw out from the sleeve rearward relative to the piston. The automatic gap adjustment device is arranged to have the hydraulic pressure received as a moving force directed toward the rear part of the spindle, to have an adjuster piston arranged within a cylinder to push and cause a protruding end part of the spindle which protrudes toward the rear of the sleeve to engage an engaging part provided within the cylinder.
