HYDRO-PNEUMATIC SYSTEM - BRAKES
D
AILY
Revi - February 2005
Location of the main brake system components on vehicles with ESP
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
- Front BREMBO 2x42 - 2x44 (model 29L - 35S);
- Front BREMBO 2x44 (model 35C - 40C - 45C - 50C);
- Front BREMBO 2x52 (model 60C - 65C);
- Rear BREMBO 1x52 (model 29L - 35S);
- Rear BREMBO 2x44 (model 35C - 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.
