Haldex has used the IAA commercial vehicles show, in Hanover, Germany, to debut its lightest ever disc brake in the ModulT air disc brake range for trucks and trailers.

The new DBT 22 MD, designed for trucks and buses, delivers a maximum brake torque of 25kNm yet weighs in at just 34kg with pads – several kg lighter than comparable competing assemblies.

The latest version of Haldex’s DBT 22 LT ModulT for trailers and semi-trailers has also been slimmed down and now weighs less than 30kg with pads, making it the lightest 22.5-inch disc brake for trailers on the market.

Also appearing in Hanover was haldex’s DBT 19 LT trailer brake offering a maximum brake torque of 18kNm.

“Haldex is entering into a new era for disc brakes, with the 22-inch model for trucks,” states Bo Annvik, president and CEO of Haldex.

“We have been demonstrating this model to selected customers since the spring with very positive response. Now it’s presented for a larger audience at the IAA show.”

Annvik says Haldex now plans to repeat the success it has achieved in the trailer market in the truck segment.

“With the technology shift in North America from drum brakes to disc brakes, we are well positioned with our current disc brake offering.”

All ModulT brakes use Haldex's ‘single-tappet’ mechanism, claimed to improve support and uniformity of pressure on the brake pads, while also reducing weight – although Annvik says all parts, including the calliper, have undergone finite element analysis to optimise weight.
