 Air Disc Brakes


Meritor is the worldwide braking leader in size and capability for the commercial and industrial vehicle industry, supplying more than two million brake assemblies per year. We are the only braking system manufacturer who can offer a complete portfolio of brakes – air disc, hydraulic disc, and air drum – as well as drums, discs and hubs. Additionally, we were the first to market with a full range or air disc brakes to suit all applications.  

Through our joint venture Meritor WABCO, our disc brake products include twin piston air disc brakes.  

Meritor’s ELSA air disc brake family is offered in Europe as an alternative to our DX series air disc brake, which was the first air disc brake to be offered on ROR trailer axles. The 225 (pictured above) installs within a 22.5 inch wheel envelope.


 Features and Benefits


The ELSA 225HE air disc brake, formerly known as the D ELSA brake, has a powerful sliding caliper design that installs within a 22.5 inch wheel envelope. It offers market-leading torque capacity with a rated torque capacity of 28,000 Nm. It also has a very large swept pad area, delivering a low pad wear rate. This advantage is compounded by extra thick pads, giving a very large wearable pad volume and extended pad replacement intervals.

ELSA brakes also feature integral automatic adjustment for pad wear, sealed synchronized twin tappet design and robust sealing of slide pins for environmental protection. The brake can be supplied with electronic pad wear sensing – an electronic pad wear warning indicator, or a simple visual wear indicator.
