Based on this page, I know it means STOP but i can't figure out what they would STOP.
Raising that target to 3 or even 4 percent as some economists have suggested would shift the outlook of firms in particular, allowing them to charge more for goods and pay more for labor without the fear that a central bank would step on the brakes."

The US Federal Reserve (FED) is mandated to maintain inflation within a targeted band. As economic activity increases, the risk of inflation also increases. By slowing down the economy, the risk of inflation abates.
One way the FED slows down the economy is by raising interest rates (stepping on the brakes).
What the article is saying is, if the FED's policy targets a high enough interest rate which already accommodates economic growth, businesses would not have to worry about the FED raising rates further (stepping on the brakes) to slow the economy down.
This is important since businesses want certainty so they can plan for the future.
