what are many have air pressure if the one drum is going up and other
one is going down
The sound pressure wave is travelling down the ear canal, hits the area of the eardrum, which vibrates ... just like a drum! Sound pressure p = force F divided by area A.
An ear drum bursts by water putting pressure on the back of it.
Check the proportionating valve.

Take the tire off and then remove the little clips from the studs. You will probably have to tear or rip them off. Dont worry they arent neccesary. The wheel will hold the drum on. Then pull the drum off. If it doesnt come off you will have to remove the little rubber cover in the back of the drum and "back' off the pads from the drum. It is a cog looking thing that has teetch going up and down. Use a screw driver to push the teeth either up or down. It will click as you do this. One way will tighten it and the other will loosen it. I never can remember if it is up or down. Good luck.
In a refinery, each piece of equipment or vessel is tied in to a relief system. So if one piece of equipment were to fail or was overpressured and needed to relieve pressure, it would do so through the relief valves into a relief header, and ultimately into a blow-down drum. The chemicals and gases cannot be released to the atmosphere so they are released to a drum.

I think a vessel is containing a fluid under high pressure whereas a drum contain a fluid with no or low pressure.

A drum trap is a plumping part used to help filter food or other debris that could go down the kitchen sink. It helps to not clog up the sink drain.
Less. If the pedal is going down, it is the master cylinder or one of the wheel cylinders leaking.
yes, too much pressure on the ear drum can damage your hearing.
