master cyl? when I push my brake pedal... it feels like i'm almost putting my foot through the floor. It's not making a grinding or squeeling noise and it's not clunking or anything... It feels like I have no brake lines.
I checked the brake fluid and it's full.
Could it be the master cylinder? Anyone else have this problem?

Well it could be the master but it might also be air in the lines or a leaky caliper piston or two. Any brake fluid leaking from the calipers? What color is the fluid; clear or black? ANy pulling to one side?
Each season I draw out the old fluid from the brake reservor with a turkey baster. I've done this for years and it workes as a cheap maintenace precaution.
I would buy a Mityvac and bleed each wheel caliper and the master to make sure your system is not filled with air. ...cheap item at around 50 claims. Make sure you have a special line wrench or a six point for this as the bleeder screws can be rusty. Try soaking them with penatrating oil overnight. If possible, hit them with a heat gun for a minute before bleeding.
