The front rotors on my 93 GXE are a bit grabby in spots, if I push the brakes at a constant pressure they jerk a bit like the rotors may be warped. I'm going to see if they can be resurfaced but they look a little thin. I will need pads and possibly rotors, is the price between aftermarket and stock pretty comparable or would the aftermarket be much more?
Thanks,
John
