Pneumatic schematic in the air brakes in any type or build of truck all work in coordination with each other for smooth driving. The brakes would not be able to smoothly stop without them.

hydraulic is liquid based, pneumatic is air.
Pneumatic elevators work on air pressure (similar to a bank's drive through suction tubes) and hydraulic elevators work on oil/water pressure.
Pneumatic system is operated by compressed air while hydraulic system is operated with pressurised hydraulic oil or any type viscous oil. Hydraulic systems can usually produce higher control forces and work under extreme operating conditions. This is the system that is primarily used on aircraft to move control surfaces and engine controls. You can often classify pneumatic systems because they have a pump (gas pump) and hydraulic systems have a piston. That is the difference. Also, pneumatic systems are louder because it is a gas under pressure. 1. By definition, hydraulics is used in controlling or harnessing power with the use of pressurized fluids whereas pneumatics studies how pressurized gases influences mechanical motion or movement. 2. Hydraulics uses an incompressible fluid medium like oil whereas pneumatics uses a compressible gas like air. 3. Hydraulic applications demand greater pressures during operations that reach thousands of pounds per square inch whereas pneumatic applications only require 100 psi pressures more or less. 4. Most hydraulic applications generally use bigger components that pneumatic applications. 5. Hydraulic systems are generally more difficult to operate compared to pneumatic applications
it works with compressed air
Cars don't use pneumatic brakes. Those are generally used on large vehicles like trains.
Pneumatic tube systems today are most seen at the drive-through windows of banks. Pneumatic tubes use pressured air to push a sealed object through the system. how do pneumatic truck trailers work?
Check you brake fluid and lines. It may be as simple as bleeding your brakes.
at a guess the brakes have still got air in the system and need bleeding properly
how penumatic lift work
It operates a cable that goes to both rear brakes and pulls them on.
1 way trailer brakes can get you killed...If you are going down a long steep grade (hill) your car/truck brakes (which are only made to stop your car or truck) will get hot and glaze over and eventually completely fail if your trailer brakes don't work properly.You will probably go over the side of the hill,crash into something and kill yourself and possibly other people.If it don't work,don't tow it.
Pneumatic machines are machines powered by compressed air. Air is compressed by a pump called a compressor, and the pressure is released as it does work, pushing on the pneumatic motors or pistons.
Try a different grade brake pad... My 2002 s-10 work truck was doing the same thing..

You don't give the make or model, but on most older trucks if it has disc brakes, they are self adjusting. If you have rear drum brakes, most of those, you put the truck in reverse, go back till you reach say 5 mph, then hit the brakes. This turns a self adjusting start screw. Back up and hit the braks agin and again till the brakes work better. If it still don't work you may just have to have need pads and/or shoes. HTH, Chuck
The Brakes on your truck. I am assuming this is a newer model with a Vacuum booster. Most likely what is happening is that there is either air in the lines and the booster is overcompensating, or there is a vacuum leak and the booster does not work because of that.
