1 thought on “brakes”

  1. Vehicle has excessive front end dive or locks rear brakes too easily

    1.Check for worn, failed or seized brake proportioning valve and replace the valve.
    2.Check for a seized, disconnected or missing spring or linkage for the brake proportioning valve. Replace missing parts or repair as necessary.
