Abstract
The drum brake (10) comprises a backing plate (11) having an anchor block (15) and shoe retainer (17) attached thereto, a parking brake lever (40) connected with one (14) of a pair of drum brake shoes (12, 14), a first pair of drum brake shoe ends (16, 18) engaging an actuation mechanism (20) and a second pair of drum brake shoe ends (22, 24) engaging the anchor block (15). A cam mechanism (50) is attached pivotally to the backing plate (11) and extends transversely relative to the plane of the backing plate (11). A parking brake cable (72) extends through an opening (25) in the backing plate (11) and is connected with the cam mechanism (50) and a second, shorter cable (70) extends between the cam mechanism (50) and an end (42) of the parking brake lever (40). Retraction of the parking brake cable (72) effects a greater displacement of the shorter cable (70) and parking brake lever (40) to effect a parking brake application.
