Went for a long drive in the country yesterday and the car started making a really nasty sound. As I turned a very tight bend at full lock, it made a screeching/scraping metallic sound coming from the front drivers side. I thought it might be because I was on full lock, although when I streightened out it carried on. I stopped and could not see anything around wheels or brakes. Checked under the car too but nothing. Pulled off and it happened again. After stopping the second time I could not make it happen and it did not come back for the rest of the journey home. Could this be the brakes sticking or something like that? The disks were quite hot. Has anyone ever had something similar? Should I be worried?
