'93 Grand Prix 3.1 automatic. 110,000 miles.
This car hasn't been driven much since I got a job 37 miles from home and I
got a Grand Am because of better gas mileage. I do drive it a little each
month to keep it working. It is always stored under cover.
This last weekend when I was driving it I noticed something wrong. When
sitting on level ground, the engine hot, I shifted from park to reverse. I
expected to start rolling before I gave it gas but it did not move. Thinking
that I must have set the parking brake, I pulled the lever, but that was not
it. I gave it some gas and it started moving with a groan. After letting off
the gas, I could feel a drag.
My first thought was the brakes were not releasing all the way. But with the
car in park and grabbing a tire I can roll the car back and forth easily.
Also when I stop after 37 miles of freeway driving, the brakes are cool.
The problem is not noticeable when the engine is cold but that is probably
due to the fast idle.
I've changed the tranny fluid and filter two or three times last time about
15,000 miles ago. The brake fluid has been changed several times too.
I've driven about 200 miles since I first noticed it and it has not gotten
better or worse.
