Abstract

Drum braking improvements for brake systems of motor vehicles, of the type comprising two parts carrying expendable friction linings, two adjacent ends of the brake shoes being held against a block of fulcrum; driving means positioned between the other two ends of the shoes to push them towards a rotating drum; a handbrake lever pivoting in a shoe in the vicinity of the drive means, which lever can cooperate with spacer means located between the shoes in the vicinity of the drive means, to push the shoes into the drum, comprising the spacer means a spacer and an automatic adjusting device intended to increase the distance between the other ends of the shoes when they are inactive, as the friction linings wear out, enabling stop means between the first shoe and the lever to define the inactive position of the lever, and enabling resilient means to maintain the lever in its inactive position, characterized in that the resilient means act on the separator and the hand brake lever in a direction substantially parallel to the axis of the drum, to maintain the lever of the handbrake against the shoe.
