Electric parking brake

This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked by a CITROËN dealer or a
qualified workshop.
For more information, see "Driving - Electric
parking brake - § Operating faults".















Only use products recommended by
CITROËN or products of equivalent

In order to optimise the operation
of units as impor tant as the braking
system, CITROËN selects and offers
very specific products.

Brake disc wear

For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.


Manual parking brake

If a loss of effectiveness of this
system is noticed, the parking brake
must be checked, even between
two ser vices.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
















Brake pads

Brake wear depends on the style
of driving, par ticularly in the case
of vehicles used in town, over shor t
distances. It may be necessary to
have the condition of the brakes checked,
even between vehicle ser vices.
Unless there is a leak in the system, a drop in
the brake fluid level indicates that the brake
pads are worn.
