Brakes problem
1992 Nissan Sentra 6 cyl Four Wheel Drive Automatic 75000 miles
----------------------------------------------------------------
After changing my front tire, I left the parking brake on and drove for about 15mins, In a hurry to get to work didnt realize it until the car was smelling of smoke. Took the brake off and I had almost no brakes at all, pedal to the floor to stop it. Do the brake lines need to just cool down? Or did I do real damage?
