Mechanic explains why skipping the parking brake is a risky business

In a now viral video, a mechanic from North Carolina broke down what happens when drivers put an automatic car into Park without putting the parking brake on.

All the weight of the vehicle rests on a small component inside the transmission known as the parking pawl.

That part is designed to hold the car still, but it is not meant to absorb constant pressure from the full weight of the vehicle all the time.

Over time, this repeated stress can wear the parking pawl down and eventually cause it to fail and when that happens, drivers may experience clunking noises when shifting out of park or, in extreme cases, rolling vehicles.

The mechanic explained that using the parking brake helps distribute the load properly, allowing the braking system to do the job it was designed for instead of forcing the transmission to take all of the weight at once.

Even on flat ground, the pressure still exists; small shifts in weight, slight inclines, or even wind can add strain and cause parking disasters.

Using the parking brake every time you park reduces that risk significantly and keeps key components working as intended.

Pawl your punches on the parking pawl

According to this mechanic, the consequences of not using your parking brake are not just theoretical.

Transmission repairs linked to parking pawl damage can cost thousands, turning a bad habit into an expensive mistake and the parking brake system is far cheaper and easier to maintain compared to transmission components.

There is also a safety element; cars that rely only on park are more likely to roll if something goes wrong internally, so using the parking brake adds an extra layer of protection and stability, especially on hills.

The North Carolinan also pointed out another overlooked benefit of remembering your parking brake.

Regular use keeps the brake cable and mechanism from seizing up due to rust or lack of movement, meaning drivers who never use it may find it fails when they actually need it.

The message is simple: using your parking brake every time is one of the easiest ways to protect your car, your wallet, and everyone around you.
