The brake is a mechanical device. I don't see touching the battery has anything to do with it. You can take out the battery and the brake still works. That's the safety design. I'd do like Mitsuguy. Also, check from the caliper all the way up, including the lines. Check if the brake pedal if it's stuck somewhere.

If happened after the battery was messed with so it should have something to do with it. I was just thinking maybe if you plugged the negative terminal first it caused a fuse to blow since you are supposed to plug the positive terminal first. Also, when removing terminals the negative should be removed first.

there is no fuse in the system that will have a negative effect on stiff brakes...
as was mentioned, brakes are 100% mechanical, the only electrically controlled item is the ABS pump, but you'd have to screw something up real bad to get it to lock in the closed position (it's a fail safe device)...
Anyways, again, it sounds like you lost your power assist.... do the brakes actually hold the car in place?

the only thing that will cause that is if your vaccume line is disconnected or if the valve is stuck i recommend changing the vaccume line /valve on the brake booster

I don't know guys, can it be that coincidental that after he connected his battery that the brakes stopped working? I mean it was working fine until he messed with the battery right?
I don't know if this link may help, but worth a shot I guess:
