You can also check each wheel after driving for 10 miles or so. Touch the center of the hub caps/wheels and feel for excessive heat. If you feel quite a bit of heat that probably means that you have a wheel that is dragging, caused by either a brake caliper that will not release or bad/overtight wheel bearing.

Yeah, I was wondering about that (the front wheel bearing service), who knows how long it has been since they have been inspected/repacked. Probably due or even overdue.

I suspect you may have a brake line or lines that are collapsing within. That situation allows for the calipers to work , but they release very slowly, at some point , they may not release. If you are having this on all wheels , look further upstream to the master cylinder , when was the last time the brakes were serviced?

I've never even heard about that "brake line collapsing within" scenario, but I am certain the brakes haven't been serviced in at least 5 years, so yeah... probably a good time to flush the fluid at least and see if any improvement. The pads themselves looked fine: plenty of meat left on them still. Also, I've not noticed any "hot brakes" smell coming from the car at all, which is a good thing, right? This car gets driven less than a thousand miles a year, so its not something I spend a lot of time driving, LOL. I sure hope I don't have to replace brake lines, heck I hadn't even considered that as a possible scenario! Approximately how much in parts cost would these brake lines & related expenses be?

That is what i really love about this forum - I gain knowledge from others prior experiences working on these cars!

Thank you both for your input, I really do appreciate it!
