What tool is commonly used to remove pistons from calipers during an overhaul?

Wrench
Compressed air
Screwdriver
Caliper tool

The correct answer is: Compressed air

The commonly used tool to remove pistons from calipers during an overhaul is actually a tool designed specifically for this purpose, often referred to as a caliper tool. This tool applies pressure to the piston to push it out of the caliper. While compressed air can sometimes be employed to aid in removing pistons, it is not the most standard or safe method due to the potential for over-pressurization and the risk of injury. In the context of caliper overhauls, a caliper tool ensures that the piston is removed in a controlled manner, minimizing the risk of damage to the caliper or piston and enhancing safety during the process.
