I changed break pad and disks both in front and rear in 2017 AUG. Then i always hear strange sound on rear wheels, i dont know why. one time by coincides. I feel the rear wheels are warmer than front wheele, i realized must be something wrong with breaks. Maybe last time the installation job was bad.  i was busy.  finally booked a time in kista shop and check. First time employee told me rear bearing is broken. replace it will fixed problem.  I payed 4000 sek. Including inspection fee which i.think i.should not pay it at all. I.didnt hear any noises so i suspect the bearing was good. I request to see the replaced part. but employee said it was scraped. I did feel good. When i drive home,the problem still there. I was very disappointed. I went to kista shop some days later and complain it, employee said they took the test drive last time , no any issue found. I had to ask a engineer go into and drive with me together.  10 mins later, he confirmed the problem. Then i book another time. This time your colleague said rear calipers was broken, need to replace. I have to pay another 6721sek.  All in all. I think i should not pay all these money ..at least the  wheel  bearing cost and redicules inspectione fee.  I give two points because you fixed car in the end. Otherwise will be only one point.
