Title: Drum brake

Abstract: A drum brake comprising a pair of brake shoes having adjacent ends engaged by a wheel cylinder and supported against a fulcrum block, respectively, is disclosed. A handbrake lever, pivoted on one of said shoes in the vicinity of the wheel cylinder, is capable of cooperating with a spacer located between the shoes in the vicinity of the wheel cylinder to urge the shoes toward a rotary drum. An automatic brake adjuster is provided between the spacer and the other of said shoes, and the handbrake lever engages the one shoe by means of a detachable abutment adapted to permit removal of the drum without resetting of the adjuster. The one shoe and the handbrake lever are received in a notch provided at one end of the spacer, and a substantially rectangular leaf spring is located between the lever and the adjacent edge of the notch to urge the lever against the one shoe in a direction substantially parallel to the drum axis.
