HYDRO-PNEUMATIC SYSTEM - BRAKES

The service brake is of the pedal type with two independent
hydraulic circuits. Both circuits are served from the
vacuum-type servo brake.
The load proportioning valve is inserted in the hydraulic circuit
of the rear brakes so as to compensate the braking action of
the rear wheels as a function of the load being carried.
By means of a servo brake the pedal acts on the twin section
master cylinder that puts the brake liquid under pressure.
Movement of the pistons in the caliper casing, as a
consequence of the hydraulic pressure, causes the brake
linings to be compressed on both surfaces of the brake disc
and therefore brings the vehicle to a standstill.
DESCRIPTION
Service brake
BRAKES
Front and Rear disc brakes
The ABS phonic wheels are fitted on the wheel hubs.
- Front BREMBO 2x48 (model 29L - 35S);
- Front BREMBO 2x48 (model 35C - 40C - 45C - 50C);
- Front BREMBO 2x60 (model 60C - 65C);
- Rear BREMBO 1x52C (model 29L - 35S);
- Rear BREMBO 1x60C (model 35C);
- Rear BREMBO 2x44 (model 40C - 45C - 50C).
- Rear BREMBO 2x46 (model 60C - 65C).
An electric wire is embedded in the brake linings which is
connected to a tell-tale light on the driving panel to indicate
the lining wear.
Emergency brake
Incorporated in the service brake, the twin circuit system
allows a single axle to brake even when the other brake is
faulty, by acting on the service brake pedal.
Parking brake
Mechanical design consisting of a hand lever and associated
linkages and wires that act on the rear wheel bakes.
