DESCRIPTION

FRONT



Each front wiper blade is secured by an integral latching pivot block (3) to the hook formation on the tip of each wiper arm, and rests on the glass near the base of the windshield when the wipers are not in operation. The wiper blade consists of the following components:

  • Superstructure (1) - The superstructure includes several stamped steel bridges and links with claw formations that grip the wiper blade element. Also included in this unit is the latching, molded plastic pivot block that secures the superstructure to the wiper arm. All of the metal components of the wiper blade have a satin black finish applied.
  • Element (2) - The wiper element or squeegee is the resilient rubber member of the wiper blade that contacts the glass.
  • Flexor (7) - The flexor is a rigid metal component running along the length of each side of the wiper element where it is gripped by the claws (6) of the superstructure.

All vehicles have interchangeable windshield wiper blades with non-replaceable rubber elements (squeegees). The blades are 37.50 centimeters (14.76 inches) long. The wiper blades cannot be adjusted or repaired and, if ineffective, worn, or damaged, the entire wiper blade unit must be replaced.
