I had it done by a shop nearby (not Isuzu dealer - no way !) I ve decided to change the pads also got OEM Isuzu (if I was doing breaks at 30K anyway) rears were replaced with $36 a pop aftermarket rotors. They do just fine. NOw I am thinking if I should've replaced fronts too at this price ???? OEM rotors are made of different material I think as after re-surface you can see the difference in metal. They are very expencive from the dealer.
