This rig will also have air ride and brakes. How do I know if those systems are ok ? Will the compressor run constantly if leaking ?
Hi stan909 - suggest you do some study on how air brake and suspension systems operate and/or take a course. Air brakes are reliable, safe systems but operate differently from hydraulic brakes found on light vehicles. Engine mounted compressors turn all the time and are designed to do so. Air supply to the tanks is controlled by the system governor.
One of the safety features of air brake systems is the system can tolerate small leaks without the instant failure that occurs when a hydraulic system springs a leak, using the unlimited medium available for transferring the pressure (the earth's atmosphere) as long as the compressor can keep up.
They are much more resistant to fade because there is no fluid to overheat, plus there can be an application gauge on the dash a driver can use to judge and control the amount of brake pressure on long downgrades etc. Air brakes can be applied indefinitely at certain low pressures (up to 20psi or so) without the system fading out.
They also have excellent parking brakes.
Leaks should be repaired.
Don't be afraid of air brakes - but learn how to operate and maintain them...
