Or
In some cases similar symptoms may be seen whilst in service

Revision history TPI - 2062184/10

Removed reference to TPI 2071166 and added instructions to clean the EPB pads, adjust the air gaps,
and retest the system. Advised that a DISS ticket should be raised with all relevant diagnostic
information if the fault persists.

Production Solution
-

Service
1. Carry out a full inspection of the (Electronic Parking Brake EPB) system including the following
components:

Right and left hand (EPB) Actuators

Right and left hand rear brake shoes (EPB) - See example shown in Figure 2

Figure 2

Right and left hand rear brake discs - See example shown in Figure 3

Figure 3

If there is no damage, refer to steps 2-5 below.

If damage is identified, raise a full DISS technical query and include all information outlined in Step 6.

2. Clean the brake shoes (EPB)
a. Remove the brake callipers as per ElsaPro repair group 43 (do not disconnect hydraulic lines unless
required).
b. Remove the EPB brake shoes from the calliper. Refer to ElsaPro Repair Group 43.
c. Inspect shoes for contamination (dust, debris, corrosion).
d. Clean the shoe surfaces and the EPB mechanism using a suitable brake cleaner.
e. Ensure all sliding surfaces are free from corrosion and move freely.
f. Reinstall or replace shoes if worn beyond specification.

3. Adjust the Air Gap
a. With the EPB brake shoes installed, adjust the parking brake air gaps according to the specification in
the workshop manual. Refer to ElsaPro Repair Group 43 ‘EPB Maintenance mode’
b. Ensure that both sides have equal and correct air gaps.

c. Confirm actuator movement is smooth and unobstructed.

4. Reassemble
a. Refit the brake callipers and torque all fasteners to the specified values.
b. Reinstall wheels and torque wheel bolts correctly.
c. Lower the vehicle.

5. Retest the System
a. Cycle the EPB through apply and release functions several times.
b. Use the diagnostic tester to run an EPB calibration/learn function if required by the model.
c. Confirm no warning messages are present and that the EPB applies/releases normally.
d. Check for even operation on both sides.

6. Information required for the full Technical DISS query if required.

IMPORTANT NOTE: Please attach the following to a new or existing full technical DISS query

Photographs/videos of the (EPB) actuator(s) must be attached to the DISS query in all cases

Request: Please also include any customer feedback regarding when the issue occurs as follows:

During an ‘Auto hold’ event

During start up/initial pull away

Whilst driving

On application of the parking brake

On release of the parking brake

How does the customer use the (Electronic Parking brake) EPB? For example:

- Is the vehicle parked without applying the EPB being applied ( ‘P’ gear selection only)

Other (please specify on the new or existing DISS query)

Comments

Please also ensure the following information is requested and/or discussed with the customer

Has the customer ever utilised the emergency stop function of the EPB switch?

Are there any noticeable noises or driveability issues which could indicate the EPB has been sticking
on?

Has there been any occasions where the EPB has not disengaged as expected / binding / sticking?

Other (please specify on the new or existing DISS query)

Comments

No further work should be conducted unless authorisation is received from Product Support via the open
DISS query
