What can you check that the spring brakes come on automatically?
-choke the wheels, release the parking brakes. when you have enough air pressure to do it, and shut the engine off. -step on/off the brake pedal to reduce to airtank pressure -the parking knob should pop out when the air pressure falls to the manufacturers specification (usually 20-40 psi) THIS CAUSES THE SPRING BRAKES TO COM ON. To check for emergency operation of spring brake on straight truck: Release park brake. Build air pressure to 100 psi. & shut engine off. Drain primary air tank & step on brake foot pedal. You should hear air exhaust from brake chambers & rear brakes should apply. This will give you controlled spring brake application if you loose primary air pressure.

How can you check that the spring brakes will come on automatically on a semitruck?
Put the key in the "ON" position with the engine off, have the vehicle in gear, push in the brake control valve (and trailer supply valve, if hooked to a trailer). Hold the brake pedal down for one minute... a single vehicle shouldn't lose more than three psi/minute, and a combination shouldn't lose more than four psi/minute. After that, you pump the brake repeatedly. You should see some sort of low pressure warning when the system gets below 60 psi (which is the hold off pressure for the spring brakes), and you keep pumping the brake. Then the brake control valve (and trailer supply valve, if applicable) will pop out, and that engages the spring brakes.
