GENERAL
Brake unions and pipes
30
The connection of the pipes between the master
cylinder, calipers, compensator and the hydraulic
assembly is made using threaded unions with a
METRIC THREAD.
Consequently, only parts specified in the Parts
Catalogue for this vehicle should be used.
Identification of parts
- SHAPE of the ends of PIPES in steel or copper
(A),
- SHAPE of the THREADED LOCATIONS on
components (B),
- pipe UNIONS coloured GREEN or BLACK:
HEXAGONAL OUTSIDE 11 mm or 12 mm (C).
BRAKE FLUID RENEWAL FREQUENCY
Braking technology, in particular for disc brakes (hollow pistons which transmit little heat, low volume of
fluid in the cylinder, sliding calipers avoiding the need for a fluid reservoir in the least cooled area of the
wheel), has allowed us to avoid the risk of vapour lock as far as possible, even if the brakes are used
intensively (in mountainous areas).
Modern brake fluids still degrade slightly during the first few months of use due to a small uptake of
humidity and replacement of the fluid is therefore recommended (refer to vehicle’s Warranty and Servicing
Handbook).
Topping up the level:
Wear of the brake pads and shoes will cause a gradual drop in the fluid level in the reservoir. This drop should
not be compensated for since the level will rise again when the pads are changed. The level should not
however be allowed to fall below the minimum mark.
Approved brake fluids:
Mixing two incompatible brake fluids in the circuit will cause a risk of major leaks, mainly due to
deterioration of the cups. To avoid such risks, it is important to use only those brake fluids which have been
tested and approved by our Technical Department and which conform to standard SAE J 1703 dot 4.

Tooling required:
- one measuring tape mounted on a base (used
for measuring underbody heights),
- an accurate pressure gauge.
1• Preparation of the vehicle:
- the vehicle must be left loaded,
- the person in charge of pressing the brake
pedal when the compensator is being adjusted
must be in the vehicle when the radius under
load is measured at the rear wheels,
- the vehicle must be on a flat horizontal surface,
which is smooth and clean (use a four post lift if
possible).
2• Marking the centre of the rear wheels:
- lift the rear of the vehicle so the rear wheels
may be turned,
- apply a chalk stick to the hub cover or the
wheel embellisher at the approximate centre of
the wheel,
- turn the wheel by hand fairly quickly, pressing
hard on the chalk. This allows concentric circles
to be drawn around the real rotation centre of
the wheel,
- mark the centre using a pencil on the chalk,
- carry out the same operation on the second
rear wheel.3• Adjusting the rear tyre pressure:
- the pressure must be adjusted with the wheels
on the ground and one person in the driver’s
seat,
- deflate the two rear wheels so that the pressure
is brought to 1.2 bar (use an accurate pressure
gauge which has been correctly calibrated),
- wait a few minutes for the air in the tyres to
return to ambient temperature since it is
cooled when the tyres are deflated and the
pressure will therefore have changed,
- adjust the pressure to 1.2 bar as accurately as
possible.
4• Measuring the radius with the vehicle
unladen:
- lift the rear wheels so that the tyres are no
longer crushed by the load on the axle (as soon
as the wheels leave the ground),
- measure the distance between the ground and
the wheel centre using the measuring tape.
5• Measuring the radius with the rear wheels
loaded:
- return the vehicle to its wheels,
- measure the distance between the ground and
the wheel centre using the measuring tape.
