Cat Data Link All control modules communicate via the Cat Data Link and work together as an integrated system to maximize production efficiency and extend component life. Oil-Cooled Multiple Disc Brakes Caterpillar four-wheel, forced oil-cooled, multiple disc service brakes are continuously cooled by water-to-oil heat exchangers for exceptional, non-fade braking and retarding performance. Extended Life Disc Brakes Extended life friction material has double the wear life of standard brakes and is twice as resistant to glazing for more consistent braking power with less noise. Brake Design Cat oil-cooled disc brakes are designed with large discs and plates for reliable, adjustment-free operation and performance. Brakes are completely enclosed and sealed to prevent contamination and reduce maintenance. Long Life An oil film prevents direct contact between the discs. This design absorbs the braking forces by shearing the oil molecules and carrying heat away to extend brake life. Pistons The Caterpillar two-piece piston design combines the service, secondary, parking brake and retarding functions in the same system. The primary piston hydraulically actuates both service and retarding functions. The secondary piston is spring-applied and held in the disengaged position by hydraulic pressure. If hydraulic system pressure drops below a specified level, the spring-applied secondary piston automatically applies the brakes. Parking Brake Oil-cooled, spring-applied, hydraulically released parking brake is applied to all four wheels for superior parking capability on all grades up to 15 percent. Hydraulic Automatic Retarder Control (HARC) Hydraulically activated automatic retarder control system electronically controls retarding on grade to maintain optimum engine rpm and oil cooling. Additional braking may be applied using the manual retarder or the brake pedal. HARC is deactivated when the operator applies the brake or accelerator controls. HARC Production Advantages Faster Speeds HARC allows the operator to maintain optimum engine speeds for faster downhill hauls and greater productivity. Superior Control Automatic brake modulation offers a smoother ride and better control in slippery conditions, allowing the operator to concentrate on driving. Ease of Operation HARC increases operating ease, resulting in greater operator confidence with less fatigue. Engine Overspeed Protection Automatically activates HARC when engine speed exceeds factory preset levels, regardless of operator inputs, to avoid potentially damaging engine overspeeds. Four Corner Retarding Four corner retarding with 60/40 percent split (rear/front) in braking effort provides superior control in slippery conditions. Balanced front to rear brake torque provides exceptional braking performance and minimizes wheel lock-up, especially during retarding. Traction Control System (TCS) Electronically monitors and controls rear wheel slippage for greater traction and enhanced truck performance in poor underfoot conditions. If slippage exceeds a set limit, the oil-cooled disc brakes engage to slow the spinning wheel. Torque is then automatically transferred to the wheel with better traction. Differential Action Normal differential action provides superior maneuvering and control in slippery conditions. Integrated Braking Control (IBC) Combines Hydraulic Automatic Retarder Control (HARC) and Traction Control System (TCS) into one integrated brake control system for optimum efficiency, performance and reliability. Fuel Efficiency The engine provides additional retarding by running against compression on downhill hauls. During retarding applications the engine ECM does not inject fuel into the cylinders for exceptional fuel economy. Caterpillar Brake System Reliable braking with superior control gives the operator the confidence to focus on productivity. » Learn More Box-Section Design The 793D frame uses a box-section design, incorporating two forgings and 24 castings in high stress areas with deep penetrating and continuous wrap-around welds to resist damage from twisting loads without adding extra weight.
