I am in Rwp. I went back to him like 2 times and all he did was sandpaper it more and more. I am going to get some good brake cleaner and ask clean it with it thoroughly, I have seen several videos on youtube and it looks ok to clean brakes with brake cleaner-- no need for sand paper. If the problem doesnt solve, ill try getting new brake shoes, any idea what genuine brake shoes will cost?
This is all started when he sand papered them, I regret that day. The sound usually comes after some time of driving and comes at low speed, its like something scratching, may be he adjusted the hand brake to be too tight. God knows.
