NASHVILLE -- With more than 1 million units already working in Europe, Haldex is bringing its ModulT Air Disc Brake to the North America. It has been in production in overseas markets since 2011, and it recently completed three years of field testing in Canada. Haldex says the ModulT ADB meets customer demands for performance, robustness, service uptime, light weight and total cost of ownership.

“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 & CEO for Haldex.

ModulT offers simplified maintenance that reduces downtime and low hysteresis that produces high braking efficiency.

“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 for Disc Brakes at Haldex.

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. Haldex says these three brakes contain more than 50% common parts which reduces part stocking complexity and eases the need for tech to train on each of the systems.

Efficient modular design

The ModulT air disc brake product line has a unique wide single-piston mechanism, which Haldex says can 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, Haldex says.

The floating light-weight caliper slides on two 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 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, says 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.
