Abstract

A pedal-operated parking brake for use in an automotive vehicle with a brake pedal lever mounted on a bracket which is secured to the vehicle body. The parking brake has a sector with teeth formed on its arcuate end portion, which is easily fixed to the brake pedal lever through a single connecting pin. A pawl having a tooth engageable with the teeth of the sector is pivotally mounted on the bracket and biased in a direction to urge the pawl to engage with the sector, and also pivotally mounted is a release lever for biasing the pawl in a direction to urge the pawl to disengage from the sector. The parking brake is provided with a damper for absorbing the shocks in stopping the rotation of the brake pedal lever and positioning the brake pedal lever. The damper includes a cylindrical resilient member which is easily mounted on a support pin which is fixed to the bracket perpendicularly to the pivoting plane of the brake pedal lever. The spring for biasing the release lever may be disposed in an opening defined in the bracket.
