i had my rear discs and pads changed to ebc turbo discs and there oe pads on my 2002 uk 300 and ever since then i seem to have a problem when turning left my right rear wheel makes a scraping noise intermittently which is quite loud i was under the impression it was the back plate on the hub which was rubbing so i pushed it back a bit and it seems to ease it off a bit but it is still there .
also when im reversing and i press the brakes i get an awfull screeching sound , and the handbrake is quite shocking to say the least when i pull it up it seems grip the wheel but when i let off the brake it rolls back a little and i have to pull it up a notch again

any help would be gratefull as im going to france in her in 5 weeks and want it sorted

 

either the discs wernt centered properly or the shoes for hand brake are chaffing inside the drum or shoes do not fit properly the discs fitted,, the bits you cant see take it back to who done the work mate
