Pneumatic Air Brakes
Controls air brake systems used on heavy trucks and trailers. Manages brake chamber pressure, relay valves, and the fail-safe spring brake mechanism that applies brakes when air pressure is lost.

Hooks
| Hook | Description |
|---|---|
init(jbeamData) | Connects to the air tank, calculates actuator volumes, and sets up the custom wheel brake update logic. |
updateFixedStep(dt) | Simulates the flow of air into and out of brake chambers. Calculates resulting brake torque coefficients for both service and parking systems. |
updateGFX(dt) | Triggers pneumatic "hiss" sound effects based on rapid changes in brake chamber pressure. |
module.reset() | Resets the controller to its initial state. |

Pneumatic Actuators
Controls individual pneumatic actuators that convert air pressure into mechanical movement. Manages valve timing, pressure regulation, and position control for pneumatic cylinders and bladders.
Auto-Level Air Suspension
Self-leveling pneumatic suspension controller that maintains target ride height regardless of load. Monitors height sensors and adjusts air spring pressure to compensate for cargo weight and weight transfer.
