Title (EN) MOLDED PISTON HAVING METALLIC COVER FOR DISC BRAKE ASSEMBLY
(FR) PISTON MOULE A REVETEMENT METALLIQUE POUR ENSEMBLE FREIN A DISQUE
Abstract:
(EN) A disc brake piston (50) includes a body (52) formed from a plastic material and a cover (70) formed from a metallic material. The body (52) of the piston (50) is molded from a synthetic resin material and is generally hollow and cylindrical in shape, defining an axis and including an opened end (56) and a closed end (54). The body (52) defines an inner cylindrical surface (58) and an outer cylindrical surface (60) which extend axially from the opened end (56) toward the closed end (54). The cover (70) is formed from steel and is integrally molded to the body of the piston (50).
(FR) Ce piston (50) pour frein à disque comprend un corps (52) en matière plastique et un revêtement (70) en métal. Le corps (52) du piston (50) est moulé en une résine synthétique et a une forme généralement creuse et cylindrique qui définit un axe et comprend une extrémité ouverte (56) et une extrémité fermée (54). Le corps (52) définit une surface cylindrique interne(58) et une surface cylindrique externe (60) qui s'étendent dans le sens axial de l'extrémité ouverte (56) vers l'extrémité fermée (54). Le revêtement (70) est en acier et est intégralement moulé sur le corps du piston (50).
