W204 Front Inner Brake Pad
When I disassemble the old brake pads, I didn't aware the inner pads ( the hydraulic cylinder side) are different and mixed up them. Now I found there has the arrow sign shown on the pad surface as the image shown. I believe the sign is to distinguish the individual pad is left or right. Thus could anyone help to advise, when the new pads are installed then the arrow sign should be pointing upward or downward?
Many thanks for your help in advance.
