SECTION 33 − BRAKING SYSTEM − CHAPTER 1
DESCRIPTION AND OPERATION
SERVICE BRAKES (see fig. 4)
The service brakes are the hydraulically operated wet disk type.
The two control pumps (one for each pedal) are located in the front part of the cab and are connected to their pedals (3) by means of tie−rods.
The pumps can be operated on their own by each pedal, or as a pair with both pedals (connected by a pin).
The connecting pipe (6) between the two pumps ensures balanced braking, even when the brake disks are not equally worn.
The control pumps are fed from a single reservoir installed on the pumps.
The brake disks (one for each rear wheel) are located between the rear transmission casing and the final drive casing. The disks are mounted on the differential drive shafts.
PARKING BRAKE (see fig. 2)
The parking brake is operated by a control lever on the left−hand side of the operator.
When acting on the control lever, a flexible tie−rod operates the lever (12) inside the parking brake support (13), bearing the brake sector assembly (10 and 11) and the brake disks (8) keyed onto the driven gear (7) and locking it.
Locking the rear bevel pinion shaft intermediate gear (7), locks the rear bevel pinion shaft too and therefore the tractor cannot move.
