I have a '12 VW Passat (66k miles) and recently the rear brakes have been squealing when backing out of parking in morning and sometimes when rolling to a stop. I first thought it was just rust build up but the sound is a high pitch squeal. Also, after 5-6 mile drive to work, the rear wheels sometimes get really hot, so hot that I cannot keep my finger on alloy wheel for 10+ seconds. It does not always happen and has happened on both of the rear wheels but always one at a time.
In one such instance of heating up, I jacked up the car and tried to spin the wheel that became hot with hand, and I could spin it with 1 finger. But when I do that, I can hear a rubbing noise once every revolution.
So I took it to the dealer and they are saying that both of the rear calipers are sticking to replace them is the only option ($$$).
Are they ripping me off here?
I bought the car as a lease return in 2015 (35k miles) and have not done any brake work on it since then. The car has been in Midwest (MI/IN/KY) all its life and since I bought it, it has always been parked outside and used for <1 mile commute to work. But I do wash it every 1 or 2 weeks in winter months. Also, I am not an aggressive driver, and generally coast down to stop lights/signs.
