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.

EXCERPT:
Hazard Lights Circuit Operation
Function:
Provides pulsating current to the hazard lights.
Operating Conditions:
Hazard light switch in the ON position.
Theory of Operation:
The hazard light switch receives unswitched power through the F4 fuse, 042C and 042D Red wires, and switched power through the 072C and 072E Red wires. The switched power is used for turn signal operation; hazard light operation utilizes the unswitched power.
In the OFF position, the hazard light switch sends switched power to the 102 Red wire and flasher relay. From the flasher relay, secondary switched power is provided to the 127A, 127B and 127C Pur wires. The 127A Pur wire supplies power to the turn signal switch, while 127B provides a connection back to the hazard light switch. (See Turn Signal Lights Circuit Operation in Section 50, Group 20.)
In the ON position, the hazard switch connects the unswitched power to the 102 Red wire and flasher relay. The internal circuits of the flasher relay provide a pulsating output if a circuit path to ground is provided through a load component (turn/hazard lights).
The lights create this circuit path when contacts in the hazard switch route the output of the flasher relay (127-series Pur wires) to both the 115-series Grn wires (left side turn/hazard lights) and 125-series Grn wires (right side turn/hazard lights). Wires 115G and 125G Grn feed back to the ICC, flashing indicator lights on the display panel.
The flasher relay also provides signals to the ICC via the 148 Gry, 144 Yel and 146 Blu wires. These signals cause the trailer 1, trailer 2 and bulb integrity indicator lights on the display panel to flash.
While in the ON position, the hazard switch indicator light is powered by the flasher relay output. This light is grounded through the 050BH Blk wire.
