When you press the parking brake pedal on a four-wheel disc car, the brake calipers on all four wheels clamp down on the brake rotors. This prevents the wheels from turning, even if the car is in gear.
The parking brake is a great failsafe in case your primary brakes fail. If you’re coming down a hill and your brakes go out, you can engage the parking brake to prevent your car from careening out of control.
How does the parking brake work on 4 wheel disc brakes?

How do screw in disc brake calipers work?
When you press the brake pedal, hydraulic fluid from the master cylinder is sent to the calipers. The calipers have pistons in them that push the brake pads against the rotor. The friction between the brake pads and the rotor slows the wheel down.
Why is my parking brake not working?
There could be a few reasons why your parking brake is not working. The most common reason is that the parking brake cable is not adjusted correctly. The parking brake cable connects the parking brake lever to the brakes themselves. If the cable is not adjusted correctly, the parking brake will not be able to apply enough pressure to the brakes to hold the car in place. Another reason why your parking brake might not be working is that the brakes themselves are not working correctly. This could be due to a problem with the brake pads, the brake calipers, or the brake rotors. If the brakes are not working correctly, the parking brake will not be able to hold the car in place.
Does the foot brake of a car stop all 4 wheels?
No, the foot brake typically only stops the two back wheels. The front wheels are usually stopped by a handbrake.
Why is it wrong to call the parking brake an emergency brake?

How do you adjust a parking brake caliper?
There are a few different ways to adjust a parking brake caliper, depending on the make and model of the vehicle. In general, however, the process involves loosening the caliper bolts, moving the caliper to the desired position, and then tightening the bolts back down. Sometimes the caliper may also need to be bled of air after it is moved.
How do you turn on a brake caliper?
Brake calipers work by using hydraulic pressure to squeeze the brake pads against the rotors. In order to turn on a brake caliper, you first need to locate the brake fluid reservoir. Once you have found the reservoir, use a Phillips head screwdriver to remove the cap. Next, use a crescent wrench to loosen the bleeder screw. Once the bleeder screw is loose, press the brake pedal down and hold it. While the pedal is pressed down, use the crescent wrench to tighten the bleeder screw. Finally, replace the cap on the brake fluid reservoir.
