Haldex has introduced its ModulT Air Disc Brake product line in North America. The company says the unique design of the ModulT Air Disc Brake meets increased customer demands for performance, robustness, service uptime, weight and total cost of ownership. By meeting the toughest demands on low weight combined with high efficiency, ModulT provides uniform stopping performance while maximizing brake effort, the company says.
“With our commitment to developing products to better serve our fleet customers, Haldex is pleased to continue to set that standard in air brake systems by introducing the ModulT air disc brake in North America,” said Bo Annvik, president and CEO for Haldex.
With a compact, modular design, ModulT is lightweight and optimized for on-highway applications. In addition to its size, ModulT provides several distinct advantages including lower weight-to-braking force ratio, simplified maintenance that reduces downtime and low hysteresis that produces high braking efficiency, according to the company.
The first member of the ModulT family to be introduced in North America is the 22.5-inch optimized trailer brake, weighing 70 pounds including pads. It will soon be followed with 19.5-inch and 22.5-inch air disc brake sizes for trucks and buses.
The ModulT air disc brake product line has a unique wide single-piston mechanism, which is able to achieve performance equal to twin-piston mechanisms, providing superior braking capability and even load distribution on the brake pads. Because the mechanism bellows seal is uniquely inverted, it protects itself against heat radiation, stones and other debris. The mechanism lever uses double roller bearings to keep the hysteresis low, which results in high efficiency and provides greater control and stability.
The floating light-weight caliper slides on two completely, environmentally sealed stainless steel slide pins. It utilizes leading edge steel PTFE-coated bushings and trailing composite bushings to produce optimized low friction caliper sliding for smoother, trouble-free operation. In addition, the slide function is lubrication-free and sealed for life so it doesn’t require grease servicing.
To simplify maintenance and reduce downtime for the fleet, the unique boltless brake pad retainer requires no special tools to replace the brake pads. The entire air disc brake design is optimized to include only two fastening bolts and no mechanism cover plate. The ModulT incorporates a reliable integrated adjustment unit to automatically compensate for brake pad wear.
“The ModulT air disc brake is the perfect solution for fleets looking for high efficiency with greater control and stability for a long service life with lower total cost of ownership,” said Jeff Stokes, global product manager – disc brakes for Haldex.
Haldex provides additional options to meet fleet demands with an optional Pad Wear Indicator (PWI), which warns of a worn out pad; or an optional Pad Wear Sensor (PWS), which minimizes pad inspection time and costs.
