Hello together, with my S70 BJ 1997 the rear brake discs/blocks, as well as the brake calipers and the cheeks of the hand brake were renewed for the last Tüv. After the change I drove now approx. 1000 km without interference. On the weekend after a ride of approx. 40 km a roaring, grinding noise appeared on the rear axle. Couldn’t detect anything by appearance – on the wheels was also no excessive heating, or for example smell of rotted brakes fixed ar. On the way home the noise was then gone again, to suddenly reappear after a distance of approx. 40km. So the whole thing seems to have something to do with the heating up of the wheels/brake system, and with a certain temperature expansion there is obviously a mechanical problem – something is beginning to grind. I guess now that the workshop did something wrong when the new brake parts were installed – I also read that obviously the hand brake a large amount of time. the V/S/C-70 family should be, and under certain circumstances can literally “explode”. If it were a wheel bearing, I think the grinding noise would be permanently present. Did anyone of you ever have a similar problem, and can give a tip?
