Abstract

L’invention concerne un dispositif de freinage (1) à tambour (2) dans lequel est positionné un piston (3) et une mâchoire (4) équipée d’une garniture (41), la piston (3) étant adapté pour déplacer la mâchoire (4) entre une position initiale permettant une libre rotation du tambour (2) et une position de freinage où la garniture (41) de ladite mâchoire (4) exerce une pression contre une paroi latérale intérieure (21) du tambour (2), ledit tambour (2) comportant aussi une biellette (5) qui dans sa position initiale autorise une libre position du piston (3), le tambour (2) comportant des moyens de fixation (6) d’une extrémité (51) de la biellette (5) sur la mâchoire (4) qui sont adaptés pour permettre un libre positionnement de la mâchoire (4) entre la position initiale et la position de freinage lorsque la biellette (5) est dans sa position initiale.
