Both of the rear brakes of our BMW X5 E53 smell like a grinding machine, the right more than the left. We assume there is a problem that causes the brake not to relief itself properly. We recognized it yesterday, because the whole surrounding of the car smelled. Yesterday was the first pretty warm day (~28°C) since a long time - could this be a coincidence?
Since there is holiday time now, the local mechanic isn't available for the next 2 weeks - as well as many of others. Is it safe to drive - let's say 35km - to drive to another mechanic?
Also, for some weeks now, it strongly vibrates but only in propulsion, could this be also related to the brake issue, or do you have any ideas which can cause this?
Would a repair likely be very expensive (> 1000€)? I know, no one can say this definitely via the internet, but we want to prepare ourselves mentally a bit before going to a mechanic. Thank you all for your help.
