E93 started making metal grinding noises when breaking then i noticed some rust dust, checked the break calipers and i think they are evaporised, weird because the right side seems fully okay, how bad it is
My car is a e92 320d 2010, it had a week ago a small small squeak in front break i thought pads need to be changed, i parked the car for a week (under a tree where there is a lot of dust) and today drove the car and it has a huge metal grinding and scraping noise coming from the breaks (even without breaking it is always there) am sure it is soo loud, also when breaking to a speed under 30kmh to full stop (or accelerating to 30 kmh) there is a grinding sound from the rear under the car!!*why would this happen just by parking the car! am so frustrated especially confused from the back grinding sounds
