Disc brake offering a balanced distribution of thrust forces applied by a piston onto at least one brake pad

A disc brake comprising a carrier, at least one first brake pad slidably mounted in the carrier, said first brake pad comprising a pad support and a friction material, a caliper comprising at least one piston slidably mounted in the caliper so as to move the first brake pad relative to the carrier, at least one actuator configured to move the piston axially, and an interposed device interposed between the piston and the first brake pad forming a spreader so as to distribute the thrust force exerted by the piston over at least two zones of the first brake pad, at least partly distinct from the projection of the piston onto the first brake pad.

An interposed device for being interposed between a piston of a disc brake and an internal brake pad support, comprising a first piece and at least two second pieces, a first ball joint between the first piece and each second piece, wherein said first piece is configured to be secured to the piston by a second ball joint and wherein said second pieces are intended to be pressed against a pad support of a brake pad.
