Air Brake System

An Air Brake system is a critical component used in heavy-duty trailers to ensure safe and effective braking. This system uses air as a medium for transmitting pressure or force from the driver control to a trailer’s brake components.

Key Trailer Air Brake Components

Air Compressor: Generates compressed air.

Air Tank (Reservoir): Stores compressed air.

Brake Pedal: Activates the braking mechanism.

Valves: Controls the flow of compressed air.

Brake Chambers: Converts compressed air into mechanical force.

Brake Drums: Generates braking force to slow or stop the vehicle.

Brake Shoes or Pads: Applies pressure to the drums or rotors to create friction and stop the trailer.

Camshaft: Spreads brake shoes apart to apply pressure to the drums.

Slack Adjusters:
