I had done 160 thousand ks in my ute with usual brake shudder issues, came time to replace brake pads and was told discs needed replacing. I had dba 4000 discs fitted with some type of ceramic pads. 5000ks later pads were down to metal and discs had massive hot spots so they replaced discs and fitted new pads. 1000ks later I informed them that it seemed like the brakes were dragging and there was a bit of disc wear occuring. I asked them if the calipers were the problem but they said they had stripped the calipers originally and they were fine. Left car with workshop for a couple of days to see if they could locate problem, they called me back said car was fine they had replaced the master cylinder. 17000ks later car is driving me nuts, driving along at 80ks steering wheel vibrating like hell, hit the brakes and its all good again, next time driving around the city brakes are dragging and you could cook a steak on the discs. anyone got any ideas beside the obvious.
