Hi all, had a few problems with my 2005 sti braking, just wanted to get some opinions on the issue before I take it in this week. It started about a week ago when I would pull to a stop , there was some resistance in the brake pedal and there was some judder. It would do this intermittently but only at when pulling to a complete stop, not when driving at normal speeds. Also not sure whether it would be related but when turning/ climbing a small ramp it sounds as if something is scraping at the back? The cars low but not enough to scrape...
Thanks in advance
Pete
