Well, its not discolored bad and it may just be from age since these wheels will be 21 years old next month.

I drove the car 56 miles today with no issues. At each stop, I checked the wheel area and the smell was just faint and the wheel itself was not hot.

I do not think its getting that hot, because at the end of my trips out, I can literally touch the wheel and its not hot at all - just warm. It just has a faint smell of hot brakes at that wheel.

Here is a photo of that wheel from a couple of months ago when someone was wanting to see a photo of my wheels...


Here is one of the front wheel that does not get hot at all - just warm as usual for front brakes. Its kinda faded, but I think its just from age.
