Hi, I have 08 rdx, and i was just inspecting my rear brake pads, on the passenger side, it has more than half an inch of pads remaining, however on the driver side, it is almost done i know uneven wears can be found between front and rears, but not side to side.

What are the possible causes of this? I know that i am going to replace the rotors and the pads and caliper pins, since it may be corroded pins,

Is this caliper problem? or any leak? Please help.

BTW i have all new fluids flushed by dealer.
