Okay, first thing is, the crome outline in front of my grill on my W126 is starting to rust pretty bad, theres about 10 rust spots now. Anyway i can stop the spread? If not is there a replacement to get for it? Also some paint around the doors is starting to rust, can i stop that/fix it?

Second, if i'm wrong on this let me know because I don't know much about it. My friends alero was starting to jerk when it came to a stop and he needed a new (spelling) roader/rudder/roader? Well, we just had new breaks put on about 3 months ago, but when i'm coming to a complete stop, a stop under 5 mph, it starts to jerk. Not when breaking from higher speeds, only around there. Is that the problem? How much is a fix/replacement?
