Abstract
A brake assembly has an auto-adjustment mechanism including an adjusting link that is rotatable to adjust an unloaded state position of a brake shoe, and an adjusting lever that operates to rotate the adjusting link during a release of the braking assembly to adjust the unloaded state position of the brake shoe. The auto-adjustment mechanism includes a pivot point mounted on a brake back plate about which the adjusting lever rotates, and an adjusting spring attached to the adjusting lever. The adjusting lever rotates in a first direction against the spring force when the brake assembly is actuated, and the adjusting spring by operation of the spring force rotates the adjusting lever in a second direction when the brake assembly is released. During the brake release, as the adjusting lever rotates back the adjusting lever catches the adjusting link in a ratchet fashion to rotate the adjusting link to adjust the unloaded state position of the brake shoes.
