COLA

Besides the soft drink, what does COLA stand for?

I should clarify. I have seen on YouTube having to do with airbrake dmv pretrip test, COLA and want to know what is stands for. Thanks

It has to do with the in cab brake/air pressure test.

Don't know if this will help or not. I don't fully understand it. But this is what I came up with doing a Google search.

• C = Air compressor cuts in.

• O = Air compressor cuts out.

• L = Low pressure warning.

• A = Air leakage.

? Check air compressor governor Cut-in pressure With the compressor off, and the engine idling, reduce the air tank pressure sufficient to cause the air compressor to cut-in (the gauge pressure will begin to rise). The air compressor must cut-in no lower than 85 psi.

? Check air compressor governor cut- Out pressure Run the engine at a fast idle. The air governor will cause the compressor to cut¬-out at 130 psi/max; normal acceptable cut-out range is from 110 to 120 psi. The air pressure shown by the gauge(s) will stop rising.

? Test Low pressure warning signal With the engine off, low pressure warning device must activate between 55 and 75 psi.

? Test Air leakage rate With a fully-charged system (typically 125 psi), turn off the engine, release all brakes and then apply full steady pressure to the brake pedal (brake on) and hold (for one full minute.) After the initial pressure drop, the air pressure should not fall more than:

• 3 psi in one minute for single vehicles, or

• 4 psi in one minute for combination vehicles.

Note: The COLA test may be performed in any order. The following order is “RECOMMENDED” for LAFD vehicles:

(1) Cut-in pressure.

(2) Cut-out pressure.

(3) Air leakage rate.

(4) Low pressure warning signal.

This one might be better. It goes backwards however. A.L.O.C.

A = Air

L = Low

O = Cut Out

C = Cut In

AIR BRAKES CHECK (C.O.L.A.)

1. AIR SYSTEM HOSES TEST: Check any leaks in the system hoses. Start engine. Build Pressure at 120 psi. Put into low gear. Stop the engine. Release all brakes. Wait the needle to stop and then hold the brake pedal and wait for 1 minute. The pressure cannot lose no more than 4 psi. The needle don’t move during 1 minute.

2. LOW AIR ALARM TEST: Key must be in the on position. Pump pedal down to range 55 to 75 psi. Alarm working at _____ psi. Put the parking brakes back. Make the truck neutral.

3. GOVERNOR CUT-OUT TEST: Start Engine. Build pressure to 100-130 psi governor cuts out automatically at _____ psi. Needle stops moving up. And no more air is coming into the air tank and the needle stops moving up.

4. GOVERNOR CUT-IN TEST: Pump the pedal down, air pressure should not go lower than 85 psi and the governor is cut-in at (around 90-95psi). The governor cut-in at ______ psi.

5. CHECK ALL BRAKES: - Check Trailer Brakes - Check Parking Brakes (tractor) - Check Hand Brakes - Check Pedal Brakes

PUT THE BRAKES (Trailer and Parking) BACK

Hope this helps.

If anyone has an easier explanation, please post it. I have done the break check several times and this is confusing me.

Keep it safe out there. Joe S
