Ford – Electronic Parking Brake (EPB) system
Two Electronic Parking Brake systems are currently supported on the service tool:
Ford Focus C-Max 2003 - present:
There are two test functions available under the calibration section of the EPB menu
these are described below.
Electronic Parking Brake (EPB) calibration function test
Checks the EPB is working correctly. This test should be performed after work has
been completed on the EPB or vehicles braking system.
The test removes any air gap from the brake pads and checks the EPB pressure.
Pre-Test conditions:
• The vehicle must be stationary
• The vehicle must be on level ground
• The brake fluid level is correct
The operator will be asked to perform a number of actions before applying the EPB.
The service tool reads and displays the EPB pressure. With the EPB applied the EPB
pressure should be approximately 1100 Newtons.
The operator will then be asked to unlock/release the EPB. The service tool reads and
displays the EPB pressure. With the EPB released the EPB pressure should be 0
Newtons.
If either of the above tests fail (pressure reading not correct) the EPB assembly should
be removed and re-assembled.
Electronic Parking Brake (EPB) emergency release calibration
Checks the EPB emergency release is working correctly. This test should be
performed after work has been completed on the EPB or vehicles braking system.
Pre-test conditions:
• The vehicle must be stationary
• The vehicle must be on level ground
• The brake fluid level is correct
The operator will be asked to perform a number of actions before applying the EPB.
The service tool reads and displays the EPB pressure. With the EPB applied the EPB
pressure should be approximately 1100 Newtons.
The operator will then be prompted to pull manually on the emergency release. The
service tool reads and displays the EPB pressure. With the emergency release
activated the EPB pressure should be 0 Newtons and the vehicle should be able to
move freely.
If either of the above tests fail then the EPB assembly should be inspected and
repaired as described by the manufacturer’s instructions.
