slam on the brakes

Halt with urgency

To slam on the brakes is to press the brake pedal suddenly and forcefully, bringing a vehicle to an abrupt stop: A deer ran out and I had to slam on the brakes.

Figuratively, it means to halt something suddenly—a project, a relationship, a plan: Management slammed on the brakes when costs spiraled.
