Abstract
A parking brake assembly is provided including a sleeve or torque tube for locking or releasing a parking brake. The assembly includes a mounting bracket, an axle extending through the bracket, and a U-shaped handle assembly secured to the ends of the axle. A ratchet is secured to the mounting bracket. A pawl is pivotably mounted adjacent to the ratchet. The pawl is connected to the torque tube by a connecting rod. A spring urges the torque tube in a first direction, thereby causing the pawl to engage the ratchet. Rotation of the torque tube in the opposite direction causes the pawl to pivot away form the ratchet, thereby allowing the operator to release the brake.
