Ok. So i went on holiday for a week, when i returned i tried to reverse off my drive but the car was stuck, like the rear breaks were locked on or something, i had taken the handbrake off obviously. I managed to get myself out of it by reversing with some power. Anyway last couple of weeks i have started to notice a high pitch screaching type of sound when driving between like 10-40mph, if i use the breaks the noise goes away. It seems to be getting louder/worse and is coming from the back end of the car. Also sometimes when i break i can hear a unhealthy noise coming from the breaks at the front(i think) like a clatter sound.
Seems i have caused some damage, any ideas?
