Hi folks abit of advice needed if u can help. My mk6 2010 astra 1.6se has a loud grinding/groan from the rear break on passenger side when reverse parking only Vauxhall have stripped the setup twice now with nothing found. I assumed it was a sticky caliper but apparently not Vauxhall have since said they can do no more for me and il just have to live with it. Anyone else experience this? Thanks
