Default A couple unrelated problems.. brakes and fuel door

Well some of you saw my intro I'm sure, but I just picked up a 90 bonneville SSE a couple weeks ago. The brakes were not feeling right when I got it, I could tell the rotors were warped, and the pedal is insensitive until I get about 2/3 down, then its OVERLYsensitive. I changed the front pads and rotors and the shaking in the steering while braking went away, but the pedal is still the same. When the car is running, if I pump the brakes 2-3 times I get the ABS and BRAKE light to come on for about 10 seconds. Also, if I hold the brake down as tight as I can, it will eventually reach the back of the firewall (when its supposed to stay pressurized, or w/e you want to call it). So, what do I do to fix that? I am going to bleed the system tomorrow and hope that helps, but maybe someone else has had a similar issue and has a better suggestion.

Now, onto a more interesting issue. I searched for this and couldnt find anything, but when I lock or unlock my doors, the fuel door opens. Is this supposed to happen? And if not, how is a person supposed to open the fuel door? Because I can't find a button for it anywhere.... I have a trunk release button in the glove box (doesnt work) but no fuel door button... Any help would be appreciated, I'm getting sick of closing my gas door every time I lock the car.

Thanks a bunch, in advance.

Sounds like it'* time to replace the Master Cylinder to me, so I don't think bleeding the system will help you in this instance.

The lock for the fuel door is tied onto the same circuit for the door locks. So when you lock the car with the power locks, the fuel door locks. Unlock the car the fuel door unlocks.

Ok, that makes sense I guess because I cant keep the fuel door closed unless the car is locked. Is the fuel door supposed to be like spring loaded, in the closed position? Because mine isnt and for this reason when the car unlocks, it pops open a little bit, then stays like that until I push it shut again.

Thanks for the help

Mine stay closed. For the longest time the lock was broken on the white car and didn't lock. Once I fixed the lock, it didn't move when I lock unlock the car.
