Default Do you have to use a parking brake when the car's in Park??

I know with MT cars I always use the P-brake because the car can "theoretically" pop out of gear. But with AT you can't take the key out unless you're in Park. So I don't use the P-brake even if I'm on a slight hill. Is this bad for the car or dangerous?

I think it's good for the p brake to use it frequently, helps keep it lubed up or some crap like that. That's what I've heard anyway..

Banging the transmission in park on a hill when you release the brake pedal is not good on the transmission. If your car is going to rock back after putting the tranny in park and releasing the brake, I'd recommend engaging the p brake to keep 'stress' off the driveline components..

If you didn't need to use it why would you have it?? Never know when Park is going to fail, or the ignition interlock switch.

You should get into the habit of putting in the parking break every time you park, even when I'm not on a hill. So when you do park somewhere on a hill you'll automatically just put it in park as routine. It doesn't hurt the car and you can never be to safe.

the main and sole purpose of the p-break is to induce power slides!!

The emergency brake on automatic cars (and manuals) is there for a reason.

Park is not a gear, its a pin stuck into your transmission/driveshaft that stops the transmission from moving. Every time you park on a hill or other unlevel surface, that slight you roll you get after letting off the brake is your car rolling back until the pin stops it. This creates stress on the pin, which will eventually wear down and break if abused. The handbrake or E-brake applies mechanical pressure to the rear brakes, stopping your wheels from turning.
