13. The brakes test

Next, I check the brakes test. (SPALE: Service-Practical-Apply-Low air-Emergency)

The first test is the service brake test. I pull ahead about 5mph then I apply my service brake and stop.

I check the vehicle both side or noise that it stops when brake is applied.

Now, I check the Practical brake test.

Release trailer brake then set tractor brake and I’m going to put in the gear and slightly start.  They hold.

Release tractor brake then set trailer brake and I’m going to put in the gear and slightly start.  They hold.

Now, I check the Apply Brake Test.

Engine OFF/key back ON / wheels chock/both valve releases.  Apply 25pounds my foot brake and hold it for 60 second.  I check the air gauge to see if the air pressure drops more than 4psi in 60 second.

I lost 0 psi so my apply brake test is GOOD.

Next, I check the Low Air warning Device test.

The low air warning device comes on air pressure should be 60 psi.  Now, I pump the brake. 

My Air warning device comes on 60 psi. That’s means my Low Air Warning Device test is good.

Finally test is Emergency brake Test.

My trailer tractor air supply valves pop out it should be between 20-40 psi air pressures.

My tractor and trailer valves pop out at about 30 psi. It is good.

The tractor trailer protection valves and parking brake valves should closed.

This conclusion of the Brake Test is good. Thank you.
