The invention discloses an adjustable oil pressure disc brake. The adjustable oil pressure disc brake comprises an adjusting screw (3), a multifunctional piston (4), a cylinder tube (6), a rear cover (10) and an upper pump body (12), wherein the adjusting screw (3) and the multifunctional piston (4) are in threaded fit, a through hole for oil feeding and discharging is formed in the middle of the multifunctional piston (4), an internal thread is arranged at one end of the cylinder tube (6) and is in threaded fit with a connector (8), a protrusion is arranged on the rear cover (10) and matched with a pit in the upper pump body (12), the upper pump body (12) is manufactured through drawing shape extrusion of aluminum alloy, and the cylinder tube (6) is installed in a through hole in the middle of the upper pump body (12). A double-sealing ring is adopted for the upper pump body, so that sealing performance is improved; the adjustable multifunctional piston is adopted for adjusting the gap between a friction plate and a disc, so that using effect is improved; a lower pump piston is made of the glass material, so that heat resistance is improved.
