A brake caliper for overlapping a brake disc, which comprises a set of pads (3, 4) and an electromechanical actuator for pressing a pad against a face of the disc, characterised in that the electromechanical actuator comprises: - an electric motor driving a first mechanical actuator and a second mechanical actuator; - the first mechanical actuator including a first drive gear and a first piston for pressing a first portion of the pad; - the second mechanical actuator including a second drive gear and a second movable piston for pressing a second portion of the pad; - each actuator (8; 9) converting a rotation of its drive gear (8d; 9d) into a translation of its piston (8a; 9a), the first and second actuator having reverse conversion senses; - a transmission module (15; 15') comprising: - a first worm screw (28; 28') and a second worm screw (29; 29') having a same longitudinal direction and having reverse winding senses while being rigidly integral with each other, these first and second worm screws (28, 29; 28', 29') being meshed with the first and second drive gears (8d, 9d) respectively to simultaneously rotate them in reverse senses; - means for rotatably driving the first and second worm screws (28, 29; 28', 29') by the electric motor, these means forming a slide connection enabling the first and the second worms (28, 29; 28', 29') to translationally move along the longitudinal direction. - an electric motor driving a first mechanical actuator and a second mechanical actuator; - the first mechanical actuator including a first drive gear and a first piston for pressing a first portion of the pad; - the second mechanical actuator including a second drive gear and a second movable piston for pressing a second portion of the pad; - each actuator (8; 9) converting a rotation of its drive gear (8d; 9d) into a translation of its piston (8a; 9a), the first and second actuator having reverse conversion senses; - a transmission module (15; 15') comprising: - a first worm screw (28; 28') and a second worm screw (29; 29') having a same longitudinal direction and having reverse winding senses while being rigidly integral with each other, these first and second worm screws (28, 29; 28', 29') being meshed with the first and second drive gears (8d, 9d) respectively to simultaneously rotate them in reverse senses; - means for rotatably driving the first and second worm screws (28, 29; 28', 29') by the electric motor, these means forming a slide connection enabling the first and the second worms (28, 29; 28', 29') to translationally move along the longitudinal direction. - a first worm screw (28; 28') and a second worm screw (29; 29') having a same longitudinal direction and having reverse winding senses while being rigidly integral with each other, these first and second worm screws (28, 29; 28', 29') being meshed with the first and second drive gears (8d, 9d) respectively to simultaneously rotate them in reverse senses; - means for rotatably driving the first and second worm screws (28, 29; 28', 29') by the electric motor, these means forming a slide connection enabling the first and the second worms (28, 29; 28', 29') to translationally move along the longitudinal direction.
