Abstract
The present invention involves an improvement in a conventional drum brake assembly which utilizes a pair of brake shoes separated by an adjustable strut. A parking brake lever is pivotally attached to one of the brake shoes and when it is rotated in a braking direction, causes both brake shoes to expand by interacting with the adjustable strut. A plate spring attached to a backing plate allows the parking brake lever to pass in the braking direction after assembly of the drum brake, thereby removing slack and properly adjusting the drum brake. The plate spring can be displaced from outside the drum brake to allow the parking brake lever to pass in the opposite direction for disassembly of the drum brake.
