Wear of brake discs, brake
pads and brake drums
The rate of wear of the brake pads
depends on the use of your vehicle
(urban use, frequent stops), and on
your style of driving or the type of
journey.
For information on checking the
discs and drums for wear, contact a
CITROËN dealer.
After washing the vehicle,
brake progressively to dry out
the brake linings.
