What is a Hand Brake?

The mechanical backup that keeps your car still when parked.

Simplified animation — not to scale.

In plain English

The hand brake, also called the parking brake or emergency brake, is a mechanical brake system that works independently of the hydraulic foot brake. It usually operates on the rear wheels via steel cables. Its main job is to stop the car from rolling when parked, but it can also be used as an emergency brake if the foot brake fails.

A simple analogy

"Think of it like a ratchet strap on a trailer. You pull the handle to tighten the strap and hold the load in place. The hand brake does the same thing — pulling the lever tightens cables that hold your rear brakes locked."

How it works

Pulling the hand brake lever inside the car tightens steel cables that run along the underside of the vehicle to the rear brakes. Inside drum brakes: the cables pull a lever on the brake shoes, forcing them apart to press against the inside of the brake drum. Inside disc brakes: the cables pull a small lever inside the brake caliper that mechanically squeezes the pads against the disc. Releasing the lever slackens the cables and springs return the brake shoes or pads to their rest position. Modern cars may use an electronic parking brake where a motor does this instead of a hand lever.
