Unassisted brake master cylinders
A . General
The brake master cylinders are attached to the pedal
console and are housed to the right of the front firewall
in the cab (Fig. 1 - Option described: single circuit).
They act on the tractor main brake located in the centre
housing.
Depending on user requirements, the master cylinders
can be activated separately or in
coupled mode via a
pedal locking mechanism (1) (Fig. 2).
The master cylinders have different characteristics
depending on the option fitted on the tractor:
• Tractor without trailer brake
Single circuit master cylinders assembly
• Tractor with trailer brake
Double circuit master cylinders assembly
The master cylinders are kept at a constant level by a
residual oil flow coming from hose (1) (Fig. 3). This
hose is connected to the lubricating and booster circuit
by a distribution block located at the front left-hand
side of the gearbox (Fig. 3).
