My 420sel seems to have a brake that hangs up slightly once in a while. It's getting to be more frequent now and causes the steering wheel to vibrate, and if I continue on it gets worse until I stop. If I leave the car in neutral and get out and grab the right front tire i can move the car forward or backwards fairly easily. This tells me the brake is not sticking that severe, but enough to vibrate the wheel and make me stop. I here a little bit of rubbing on the right front more so than any other wheel that's what makes me believe it might be that one. I'm looking for Ideas because I dont have alot of money to throw at this problem for no reason, because it needs all 4 tires and a complete exhaust system (tires dry rot and exhaust got hole as soon as I took it out of storage New England is great! Thanks for any input on this problem, and happy motoring!! cb
