An elastic return spring for axially returning a brake pad of an automotive disc brake from an active position to an inactive position, the spring being intended to be interposed between the brake pad and a fixed support, with an elastic deformation portion, a carrier portion arranged to be fastened to the fixed support of the disc brake, and a pad portion. The carrier portion includes a support part and a connection part which including at least one connection fold arranged and configured to bear on an anchoring part of the fixed support and to cooperate with said anchoring part to avoid any lifting of the connection part.

Disc brake comprising at least one elastic return spring for a brake pad, elastic return spring, replacement kit and mounting method

A brake caliper comprising: a set of brake pads positioned on each side of a brake disc; a first actuator including a first drive gearwheel driving a first mobile piston pressing against a first portion of brake pad in order to move same; a second actuator including a second drive gearwheel driving a second mobile piston pressing against a second portion of the pad in order to move same, with a mode of operation that is the opposite of that of the first actuator; a first and a second worm screws which are secured to one another and of opposite hand to one another, rotationally driven and capable of translational movement in their longitudinal direction and in mesh with the first and second gearwheels respectively in order to turn these in opposite directions.

Electromechanical-type disc brake caliper comprising two mechanical actuators to compensate for an uneven wearing of the one same brake pad

A disk brake includes a disk overlapped by a caliper, at least one pad carried by the caliper, two different actuators, each one including a pinion and a mobile piston for pressing the pad against the disk by rotation of the pinions, a rotating shaft including two endless screws having opposite winding directions, the shaft being mobile in translation in the longitudinal direction thereof, and an electric motor for driving the rotating shaft. The rotating shaft extends between the two pinions with the two endless screws thereof each engaged in a pinion.

Electromechanical disc brake comprising a transmission compensating unequal wear on the same pad

A brake includes a caliper overlapping a disk. The brake also includes a first pad and a second pad which are carried by the caliper on either side of the disk. The brake further includes a first actuator including a first primary toothed wheel driving a first mobile piston pressing against the first pad in order to move same. The brake further includes a second actuator including a second primary toothed wheel driving a second mobile piston pressing against the second pad. The brake further includes a rotating shaft including a first and a second endless screw having opposite winding directions, the shaft being movable in translation. The brake further includes an electric motor for driving the rotating shaft. The first and second endless screws are engaged in the first and second primary toothed wheels respectively.
