Cat Data Link. All control modulescommunicate via the Cat Data Link andwork together as an integrated systemto maximize production efficiency andextend component life.

Oil-Cooled Multiple Disc Brakes.Caterpillar four-wheel, forced oil-cooled,multiple disc service brakes arecontinuously cooled by water-to-oilheat exchangers for exceptional, non-fade braking and retarding performance.

Optional Extended Life Disc Brakes.Extended life friction material has doublethe wear life of standard brakes and istwice as resistant to glazing for moreconsistent braking power with less noise.

Brake Design. Cat oil-cooled discbrakes are designed with large discsand plates for reliable, adjustment-freeoperation and performance. Brakes arecompletely enclosed and sealed toprevent contamination and reducemaintenance.

Long Life. An oil film prevents directcontact between the discs. This designabsorbs the braking forces by shearingthe oil molecules and carrying heataway to extend brake life.

Pistons. The Caterpillar two-piece pistondesign combines the service, secondary,parking brake, and retarding functionsin the same system. The primary pistonhydraulically actuates both service andretarding functions. The secondarypiston is spring-applied and held inthe disengaged position by hydraulicpressure. If hydraulic system pressuredrops below a specified level, thespring-applied secondary pistonautomatically applies the brakes.

Parking Brake. Oil-cooled, spring-applied, hydraulically released parkingbrake is applied to all four wheels forsuperior parking capability on all gradesup to 15 percent.

Hydraulic Automatic Retarder Control(HARC). Hydraulically activated automaticretarder control system electronicallycontrols retarding on grade to maintainoptimum engine rpm and oil cooling.Additional braking may be appliedusing the manual retarder or the brakepedal. HARC is deactivated whenthe operator applies the brake oraccelerator controls.

Four Corner Retarding. Four cornerretarding with 60/40 percent split(rear/front) in braking effort providessuperior control in slippery conditions.Balanced front to rear brake torqueprovides exceptional braking performanceand minimizes wheel lock-up, especiallyduring retarding.

Traction Control System (TCS).Electronically monitors and controlsrear wheel slippage for greater tractionand enhanced truck performance in poorunderfoot conditions. If slippage exceedsa set limit, the oil-cooled disc brakesengage to slow the spinning wheel.Torque is then automatically transferredto the wheel with better traction.

Differential Action. Normal differentialaction provides superior manueveringand control in slippery conditions.

Integrated Braking Control (IBC).Combines Hydraulic Automatic RetarderControl (HARC) and Traction ControlSystem (TCS) into one integrated brakecontrol system for optimum efficiency,performance and reliability.

Fuel Efficiency. The engine providesadditional retarding by running againstcompression on downhill hauls. Duringretarding applications the engine ECMdoes not inject fuel into the cylindersfor exceptional fuel economy.

To determine retarding performance: Add lengths of alldownhill segments and, using this total, refer to properretarding chart. Read from gross weight down to the percenteffective grade. Effective grade equals actual % grade minus1% for each 10 kg/t (20 lb/ton) of rolling resistance. From thisweight-effective grade point, read horizontally to the curvewith the highest obtainable gear, then down to maximumdescent speed brakes can properly handle without exceeding

cooling capacity. The following charts are based on theseconditions: 32° C (90° F) ambient temperature, at sea level,with 37R57 tires.

NOTE: Select the proper gear to maintain engine rpm at the highestpossible level, without overspeeding the engine. If cooling oiloverheats, reduce ground speed to allow transmission to shift tothe next lower speed range.

To determine gradeability performance: Read from grossweight down to the percent of total resistance. Total resistanceequals actual percent grade plus 1% for each 10 kg/t (20 lb/ton)of rolling resistance. From this weight-resistance point, read

horizontally to the curve with the highest obtainable gear, thendown to maximum speed. Usable rimpull will depend upontraction available and weight on drive wheels.
