I have a 1993 GXE and recently I've noticed a rotten egg smell coming from my car right before parking it. I have to have the windows rolled down to smell it, and its only happened once or twice. I think it might be coming from the exhaust or under my car.

Also, I've noticed after driving my car that my real wheel has a slight odor that resembles burnt plastic or rubber. You have to get close to the tire to notice it, but its there.

When I first begin driving my car, my brakes tend to squeak. Would any of you know what the problem(s) is?

Ooohhh not too good. I assume you meant rear wheels. Well that smell you're getting is the brake shoes constantly rubbing against the drum. A possibility might be that you're parking brake is not releasing all the way. Or the wheel cylinder is not working properly.

Better have it checked out. ASAP.

Only the right rear wheel has the odor. The left rear wheel is fine.

Still have it checked out. Something is not letting your brake shoe retract from the drum.

Would could be causing the rotten egg smell?

the rotten egg smell could be coming from a clogged catalytic converter

exhaust studs and bolts..thats what it was 4 me
