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

A method for manufacturing a sliding caliper disc brake, wherein the disc brake comprises at least one first brake pad slidably mounted, 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, 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, wherein the interposed device comprises a first piece and at least two second pieces and a first ball joint between the first piece and each second piece,

• wherein the disc brake comprises a second brake pad, a first guide pin and a second guide pin allowing sliding between the caliper and a carrier, at least the second guide pin allowing rotation of the caliper about the first guide pin, and wherein the caliper comprises an arch and a nose configured for applying a force to the second brake pad, the method comprising:
• manufacturing a caliper comprising a body comprising a housing for a piston and an electromechanical actuator and an arch of a dual-piston disc brake,
• manufacturing a piston with a connecting element,
• mounting said piston in the housing of the caliper body,
• manufacturing a carrier of a dual-piston brake,
• assembling the caliper and the carrier by mounting a guide pin between the carrier and the caliper,
• placing the caliper into a raised position,
• mounting the first and second brake pads of a dual-piston brake into the carrier,
• manufacturing an interposed device,
• mounting the interposed device against the first brake pad support,
• pivoting the caliper towards the carrier, with the connecting element of the piston cooperating with the first part of the interposed device,
• installing the second guide pin between the carrier and the caliper.
