Hydraulic fluids are most important in construction machines, as it plays major role in operations and has heavy lifting capacity due to its incompressible characteristics.
Hydraulic actuated brakes will dissipate heat thoroughly and distribute heat more evenly than traditional mechanically actuated brakes, which means that hydraulic actuated brakes are more likely to last longer.
This cause is due to brake fluid that resists heat and compression in a hydraulic brake system. The final results increase safety in machines, slippage in rough terrains and precise stopping power in heavy operations to prevent productivity-robbing slippage.
Hydraulic brakes are also one of the most accessible systems to repair due to the readily available disc brake parts. They are regarded as sealed off closed systems because they do not lose fluid when functioning correctly. Therefore, it leaks only when the brake system is damaged.
Many OEM’s are working on large-capacity, continuously cooled, wet-multiple disc brakes that also function as a highly responsive retarder, which provides the operator greater confidence at higher speeds when traveling downhill. As Larger brakes have extra thermal capacity—the ability to absorb heat without fading on long downgrades.
Komatsu, Volvo and other OEM’s are working on advanced technologies like traction control system, Hill Decent control and Hill hold assist which monitors wheel speed and automatically engages and disengages the service brakes at individual wheels to limit tire slip, with slight adjustments in differential.

Global construction equipment brake market is estimated with $XX Billion currently, growing at XX% CAGR till 2030.
Recently Komatsu Articulated dump trucks are equipped with new tech wet disc brakes located on the ends of the front and middle axle, to improve safety and Productivity and their new Off-Highway Truck HD785-8,is enhanced by standard features as wet multiple disc brakes on all four wheels and automatic traction control, which automatically applies pressure to independent brake assemblies for better traction in a variety of conditions. This eliminates the need for differential lock-up, allowing better steering performance.
The wet disc brakes are designed to improve downhill brake performance. This truck is suitable for mining, quarry and aggregates operations, which automatically applies pressure to independent brake assemblies for better traction in a variety of conditions.
Articulated dump trucks developed by Caterpillar has all-axle wet brakes which reduces owning and operating costs, weight and downtime while improving braking performance.
The company attributes a nearly 3-percent productivity boost to these new brakes. In addition, the brakes are responsible for a 5-percent fuel efficiency boost.
Bell articulated trucks come configured for a pedestrian detection system (PDS). They provide the interface and electronically controlled brake valve required for PDS. Only suppliers that have successfully tested their PDS interface with Bell can install the equipment on these trucks and this will be effective with the 2021 models.
