Brake pedal feels high and hard

Is this bad? I recently had to remove the rear brake rotors to troubleshoot and fix a mess I made with the parking brake shoes. After I put it all back together (same pads and rotors) and started driving it, I noticed that the brake pedal feels like it sits a little higher, or at least like I have to push in less in order to star stopping the car. Also, it does not go in very far even when I push it in hard.

Discuss.

It's cool, Shahab. Maybe I somehow let air into the system (that would be why, right?) without knowing. The weird thing is that I didn't open, lose, or unscrew anything.

I thought that air in the system would show up as a smushy pedal, but I gather from everyone's posts that a stiff pedal can also come from that.

I guess I should take care of this before I leave for St. Louis this coming Friday. Would you drive 800 miles under my current conditions?

Be ready for this:

"Uh, Eric..... yeah -- Daniel here man. Dude, I'm not gonna make it. My brakes bailed on me here in Springfield."

Or simply don't be surprised if I show up in a Civic.

I appreciate the input. I understand that I should "try bleeding the system," but I need to know if this is urgent, life-or-death stuff, or if I can drive to St. Louis this weekend and take care of this next week.

Why is stiff pedal bad?

Gator is an unknown quantity at this point
Air in the brake lines causes a soft pedal and more pedal travel than normal. I have never heard of air in the brake lines causing a hard pedal. Think about it. Under braking the air compresses and thus a soft pedal, not a hard one.
If the brakes work fine, I would say you probably don't have a problem. They just feel different because of the brake job. Have another BMW owner drive it and see if they say the brakes feel abnormal. If something is amiss, it is probably mechanical in the way the brakes were reassembled.

SOLO5977 is on a distinguished road
DEFINATLY not air in the system!!!! Air = soft pedel because the air can be compressed where as the brake fluid can not. It sounds to me that something isn't seated right. or that the problem you made with the parking break has something to do with it. Unles you are really familure with breaks I would not do it your self it will save you much head ach if you have it done

^^ The compressibility of air is exactly what prompted me to question the presence of air in the lines. I haven't looked at my brakes since the weekend, so there is a possibility that something is not seated right. I will take a look again to be sure.

a firm pedal feel and less travel means things are working CORRECTLY.

long pedal travel and soft pedal means shit is worn out or has air in the system.

a perfect braking system (perfect in terms of a race car) has near zero pedal travel, the only modulation you have is the effort applied to the pedal, the pedal may appear to not move at all.
