Key Features & Benefits

A governor basically controls the air pressure in your air brake system. It has a few jobs – it builds up air pressure when you’re driving, maintains a safe level of pressure even when you're not hitting the pedal, and it’ll apply the spring brakes if the air pressure drops too low – like if there's an air leak or the compressor fails. It also regulates how quickly air builds up, preventing overcharging the system. Think of it as the central control for your entire air braking setup. It’s a core part of your air brake system, naturally. It sits within the air processing unit, working with the compressor, the dryer, and the unloader valve. It's what makes the brakes work consistently and safely. It’s a critical link between your foot on the pedal and actually stopping the vehicle.

Symptoms, Risks & Replacements

It’s super important for safety, plain and simple. If the governor fails, you could lose braking power, or your spring brakes might unexpectedly engage. It acts like a shield against system failures. You’ll notice if it’s going bad usually because your brakes will feel spongy, or your air gauges will read abnormally. If you suspect an issue, it needs addressing immediately. You can find a good replacement at places like Fixparts Online, and honestly, it's something you don't want to put off. It’s a key component to keeping you and everyone else on the road safe.
