One-way and two-way brake auto-adjusters

A brake assembly that transitions between an unloaded stated and a loaded state, wherein the brake assembly is actuated to transition from the unloaded state to the loaded state and is released to transition from the loaded state to the unloaded state, the brake assembly comprising:

• a friction member;
• a brake shoe that interacts against the friction member to apply a braking torque when the brake assembly is actuated;
• and
• an auto-adjustment mechanism that automatically adjusts an unloaded state position of the brake shoe relative to the friction member;
• the auto-adjustment mechanism comprising:
• an adjusting link that is rotatable to adjust the unloaded state position of the brake shoe, 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, an adjusting spring attached to the adjusting lever, and a pivot point about which the adjusting lever rotates in a first direction when the brake assembly is actuated and in a second direction opposite from the first direction when the brake assembly is released;
• and
• the brake shoe comprising an end pad positioned at an end of the brake shoe and that contacts and drives a first end of the adjusting lever when the brake assembly is actuated to rotate the adjusting lever in the first direction against the spring force of the adjusting spring, and the adjusting spring by operation of the spring force rotates the adjusting lever in the second direction when the brake assembly is released.
