Here is the background info to my problem:

I own a 2003 Honda Accord LX. I was away on vacation for two weeks during which time no one drove or even started my car. When i got back it started up just fine but i didn't drive it anywhere. Then my friend's car's battery died in my driveway so he jumped it using my car.

Ok, so that is the background info. Then a couple days ago I tried to pull out of my driveway but the ABS light was on on the dashboard and the passenger side front brake was locked up making it virtually impossible to drive.

Do you have any suspicion what might be the cause of this problem?

Please note that yesterday I unhooked the battery for several hours to see if a reset would work. No dice!... Thanks!!!!
