Checking Air Brakes

Newbie777:
]III] I’ve watched a video of the module 4 test and it talks about walking around with engine off. Then goes on to say have someone help you or use something to wedge against brake pedal. Now what are you looking for when you press the pedal down which you could not do with walking around the vehicle? I thought this help/wedging business was more to do with checking the brake light

Im guessing air leaks will be easier to hear if the foot pedal is pressed continuously,

Newbie777:
] do you do this every shift or is that unnecessary?

I test brakes twice a week unless i get put in different vehicle
