According to the company, the unique design of the ModulT Air Disc Brake meets increased customer demands for performance, robustness, service uptime, weight and total cost of ownership. ModulT provides uniform stopping performance while maximizing brake effort, Haldex 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,” says 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.
Originally introduced in Europe in 2011, the ModulT has nearly a million global units in operation. The first member of the ModulT family to be introduced in North America is the 22.5-in. optimized trailer brake, weighing 70 lbs. including pads. It will soon be followed with 19.5-in. and 22.5-in. air disc brake sizes for trucks and buses, Haldex says.
Efficient modular design
Haldex says 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.
Simplifies maintenance
To simplify maintenance and reduce downtime for the fleet, Haldex says 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,” says Jeff Stokes, global product manager – Disc Brakes for Haldex.
He adds, “You can change the pad in less than one minute with no tools.”
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.
