Brake pads

Brake disc wear

If a loss of effectiveness of this
system is noticed, the parking
brake must be checked, even
between two services.
Checking this system must be
done by a CITROËN dealer or a quali-
fi ed workshop.

















Only use products recommended
by CITROËN or products of equiv-
alent quality and specifi cation.

In order to optimise the opera-
tion of units as important as
the braking system, CITROËN
selects and offers very specifi c
products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compart-
ment is strictly prohibited
.



Manual parking brake

For information on checking
brake disc wear, contact a
CITROËN dealer or a quali-
fi ed workshop. Brake wear depends on the
style of driving, particularly in
the case of vehicles used in
town, over short distances. It
may be necessary to have the
condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the system, a
drop in the brake fl uid level indicates
that the brake pads are worn.
