1st week of brakes

I've gained so much more insight on how the air brake system works. I used to just perform tasks without knowing the functionality/purpose of components. I would build air, release the parking break, change the shoes and components, and adjust the brakes. Now I understand how the S-cam, slack adjuster, and shoes work together to stop a truck. I grasp a lot better what's actually happening when an operator applies the service brake and what could fail.
