How much damage?

Typically, the e-brake is only on the rear tires. Check the full circumference of the tires. If the rear tires didn't roll, you may have worn a flat spot in the tires. If they did roll, you likely got some pretty hot rear brakes. Possibly glazed pads or warped rotors? I don't know the specifics of the rear brakes on your car.

Probably little or no damage. What's done is done, shouldn't worry about it now. Continue to enjoy your new XT and keep it well maintained =)

The most you can do right now if you just want peace of mind is take it in for a rear brake inspection. It wouldn't hurt...it'll only cost a little $$ and some of your time...But most likely, little or no damage...

The parking brake is a small drum brake which uses the inside of the disc brake hub as the rotating friction surface. The parking brake lever doesn't actuate the rear disc pads.

You probably wore the linings of the parking brake shoes very badly, given that you *heard* before you noticed they were on.

You should have someone inspect your parking brakes, but it's unlikely to have affected the rear discs that are used when you press the brake pedal.

=====================================================

Everything stu said is true. He meant rear brakes, not tires. You're an idiot al.

Emergency brakes operate the rear brakes.

If the brake was set tight enough the rear wheels will not spin and the tires will be worn flat on one spot.

If they were set somewhat lose, she was riding on the brakes and wore down the pads. This results in lots of friction, results in lots of heat. The heat can glaze the pads and can warp the rotors if the e-brake runs on rear discs.

Excessive heat can damage the wheel bearings and/or the oil seal.

you wont glaze the pads !!!

or warped rotors?

You wont warp the rotors !!

I don't

very true
