Abstract
A foot-operated device for controlling a parking brake wherein a parking brake pedal is locked in its operated position through engagement of a pawl member with ratchet teeth. The pawl member is pivotally connected to the brake pedal, and the ratchet teeth are formed on a bracket fixed to a vehicle frame. The parking brake is released when a pedal pad pivotally connected to the brake pedal is pivoted on the pedal and the pedal is depressed. The pedal pad has an extension arm protruding toward the pawl member which is biased by a spring device in a first direction to cause the pawl member to engage the ratchet teeth while the pedal pad is placed in its original position. The extension arm directly engages the spring device to change the biasing direction thereof from the first direction to a second direction so that the pawl disengages from the ratchet teeth when the pedal pad is pivoted to its operated position. The biasing force in the second direction is selected to be smaller than an engagement force existing between the pawl member and the ratchet teeth.
