Air Disc Pads

Engineered for Safer Braking, Longer Life

The A-Line KZ-series of air disc pads are engineered with a proprietary blend of High Torque Fibers (HTFs) and Modified Crosslinking Resins (MXRs). This series is engineered for applications ranging from on-highway to severe duty. Because air disc braking generates extreme heat and torque, A-Line pads were designed to withstand the most demanding applications. 

Beginning with the backing plate and Encapsulated Mechanical Retention System (EMRS), A-Line exceeds OE specifications for shear strength and backing plate integrity. A Q235b grade steel backing plate is used to withstand 30,000 psi of yield strength, and is then fortified with A-Line’s StrataBond® shear strength reinforcement.

Different Loads Require Different Formulations

Not all heavy duty vehicles, loads or drivers are the same. So A-Line created different frictions to meet your needs. We started with High Torque Fibers (HTFs) and added Modified Crosslinking Resins (MXRs) to resist extreme heat. That means A-Line pads can continue to deliver higher torque when you need it.

Burnishing Strips Perfect Brake Geometry

Noise and vibration are some of the leading causes of premature pad replacement. A-Line brake pads are positive molded and finished with microabrasive burnishing strips to seat the pad to the rotor. This creates a perfected brake geometry that reduces noise and vibration, extending your brake life.

Stratabond® Retention For 300% More Shear Strength

A-Line’s StrataBond® system increases shear strength and reduces brake noise using this four-part component strategy.
1. StartaBond backing plates use an integrated mechanical retention system that allows friction to fully encapsulate it.
2. A phenolic resin-based thermal-set adhesive is applied to the backing plate to bond the friction to the retention system.
3. Proprietary high-resin, high fibre friction formulation is applied to create a 3mm stabilizing layer that cross-links the resin polymers in the adhesive and stabilizing layer to increase shear strength.
4. A high torque, low noise formulation is applied as the friction layer. Under pressure the friction resin and fibres form a cohesive bond to the stabilizing layer.
