The WABCO WABCO MAXX22 Air Disc Brake (part number 6403220770) is a replacement component for the air brake and air suspension systems of heavy-duty trucks, buses and semi-trailers. It is built to original equipment specification from quality materials, so it installs on the original mounting points and performs reliably throughout the service life of the vehicle. Key ratings include Applicable Wheel Rim 22.5‑inch, brake disc thickness 45 mm, maximum braking torque＞30000 Nm, Stroke 21 mm, mounting bolts 6*M18*1.5, weight approx.39 kg.

The lightweight monoblock caliper and high-strength clamping structure deliver powerful, well-balanced braking with low weight. A built-in continuous wear sensor reports pad condition in real time, so maintenance can be planned instead of discovered, and the robust design gives long, dependable service life.

Every unit is manufactured to original equipment specification and inspected before it leaves the factory, so it matches the fit, function and durability of the original part. Sealed, vibration-tested construction keeps performance stable in the heat, dust, road salt and constant vibration found on commercial vehicles, and standard interfaces make installation and maintenance straightforward. Spare parts, technical data and fitting advice are available on request.
