Well once I do have the same problem after changing the engine and getting it endorse. Send to the mechanic and they change the break shoes. But he did change both my break pad with original parts and tigthen the break. Gone to puspakom but forgot to put away the old break pad. So it is left on the front passenger sit. Maybe you need to do it that way?😆
