On a twisty, winding road with a 53-foot trailer in tow, safety is your main concern. Fully functioning air brakes are absolutely necessary for this scenario, which is why you had your mechanic check the air brake chamber and other components before leaving. This chamber converts compressed air into the mechanical force that stops the vehicle. Air brake chambers are usually on each wheel for maximum efficiency, and all wheels require maintenance to ensure proper functioning. Other components in the system include fittings and air brake hoses, which come in bulk rolls of 180 feet or more. Hoses can typically handle high pressures of 2,000 psi or more, which is ideal for an air brake system. Air brake fittings attach to the ends of the hoses and use compression to withstand the high pressure in the system. The air brake chamber and other components in an air brake system are essential to smooth stops and safe driving.
