Abstract

L'invention concerne un ensemble de frein à tambour (10) et d'outil de déverrouillage (30) du frein à tambour (10), le frein à tambour (10) comportant un plateau (12) de support, un actionneur linéaire (16) et un motoréducteur (18) entrainant l'actionneur linéaire (16), l'actionneur linéaire (16) et le motoréducteur (18) étant montés sur le plateau (12) de support, dans lequel le motoréducteur (18) est fixé au plateau (12) par une pluralité de vis (24) et est accouplé à l'actionneur linéaire (16) par l'intermédiaire d'un organe d'accouplement (20) relié à l'actionneur linéaire (16), caractérisé en ce que l'outil de déverrouillage (30) consiste en un élément unique comportant une première extrémité (34) destinée à coopérer avec chaque vis (24) pour le serrage ou le desserrage des vis (24) et comporte une deuxième extrémité (36) destinée à coopérer avec l'organe d'accouplement (20) lorsque l'actionneur linéaire (16) est démonté pour l'entrainement de l'actionneur linéaire (16) par l'outil de déverrouillage (30).
