8 Braking system
Note: Before assuming that a brake problem exists, make sure that the
tyres are in good condition and correctly inflated, that the front wheel
alignment is correct, and that the vehicle is not loaded with weight in an
unequal manner. Apart from checking the condition of all pipe and
hose connections, any faults occurring on the anti-lock braking system
should be referred to a Peugeot dealer for diagnosis.
