Purpose/Function

• Detects the vacuum in the power brake unit and sends it to the electric vacuum pump control unit as a power brake unit vacuum pressure signal.

Construction

• Installed to the power brake unit.

  

• The vacuum sensor 1 has adopted a piezoelectric element to the detection area for detection of the vacuum in the power brake unit.
