 Drum Brakes

Meritor enjoys a market-leading position with cost of ownership optimized through the application of advanced predictive techniques and innovative manufacturing processes. We are the world’s largest producer of Z-cam, S-cam and wedge air drums for trucks. Through our Aftermarket business, we provide Meritor, Euclid and Fras-Le replacement parts.


One example of an industry-leading offering is the Meritor Q Plus™ (pictured above) cam brake. Performance, serviceability, dependability, simple operation and proven design are the factors that have made the Q Plus an industry standard. The Q Plus increases service life and mileage between relines by using thicker lining blocks. Because of these thicker linings, we specially designed an S-cam and heavy-duty shoe return spring to provide additional brake shoe travel for full wear. An improved camshaft bushing also contributes to longer service life.  

Q Plus brakes are available for steer, drive and trailer axle applications and provide greatly enhanced stopping power. In their high performance steer axle application, for example, there is up to 100 percent more torque and 65 percent more wearable lining than standard 15” x 4” brakes.

 
 

 Features and Benefits

Our Q Plus™ brakes feature linings with extra thickness at the maximum wear point and improved camshaft bushing to help ensure an increased service life. 

The shoes are of a quick change design for ease of serviceability and our focus on parts commonality among steer, drive and trailer brakes help customers to effectively reduce parts inventory.
