The invention relates to a heavy truck electric control mechanical disc type brake, in particular to a disc type brake applicable to an electromechanical brake system (EMB). Two sliding pin floating clamp bodies are adopted in a braking clamp. According to a double-push-rod thrust executing mechanism, two ball screw pairs are used for converting the rotation motion into thrust for a friction plateduring braking, and meanwhile the thrust executing mechanism integrates the automatic braking gap adjusting function. A power distribution mechanism averagely distributes source power to the two ballscrew pairs, and the synchronous motion of double push rods is achieved. A planet speed reduction mechanism conducts deceleration and torsion increasing on the rotation motion, and a power output mechanism comprises a driving braking part and a parking braking part. The power distribution mechanism divides power into two parts input to the two ball screw pairs respectively, the ball screw pairs convert the rotating motion
