A piston is typically found in internal combustion engines, where it moves up and down within a cylinder to compress fuel and air, enabling combustion. They are also used in hydraulic systems, such as hydraulic lifts and brakes, where they help transmit force. Additionally, pistons can be found in pneumatic systems, like air compressors, where they compress air.

Which piston? what's wrong. If it's a piston in the engine, you'll need a major rebuild. If it's a master cylinder or wheel cylinder piston, just replace the cylinder, it's not worth the trouble.
Increasing the pressure inside the piston cylinder would cause the piston to lower since the higher pressure pushes down on the piston.
Buy a small universal piston retractor from an auto supply shop (square in shape with strange different shapes coming out of it) find the correct side of the tool, the one that best fits the grooves on the piston. Attach the piston retractor tool to your ratchet Rotate the piston back into the caliper as you would with a bolt or screw.
If the output piston of a car hoist is replaced by a piston of twice the area, the output force would double. This is because the force exerted by a hydraulic system is directly proportional to the area of the piston. Since the new piston has twice the area, it would exert twice the force on the car lift.
Decreasing the pressure inside the container or increasing the weight on top of the piston would cause the freely moving piston to lower.
The piston rings may be worn out .
it would be better to buy a piston kit. It wouldn't be a good idea to try to fix a cracked piston.
the piston would push air down and fluid up.
Worn piston rings, bad valve seals,
To calculate the piston area, use the formula ( A = \pi r^2 ), where ( A ) is the area and ( r ) is the radius of the piston. First, measure the diameter of the piston and divide it by two to find the radius. Then, square the radius and multiply by π (approximately 3.14159) to obtain the piston area in square units.
Reducing the pressure or increasing the volume of the system would cause a freely moving piston to lower. This change would decrease the force acting on the piston, allowing it to move downward due to the pressure difference.
