What do you think? 3 visible. grooves

Do I need to change out the pads? Rotor and Pads all original. Other wheels are smooth with no groves. Plenty of life left on the pads.

Like many others, I've changed out my pads on vehicles over the years and never machined the rotors. Getting a bunch of sand in one wheel's pad/rotor contact area can make the grooves. But 95% of the rest of the rotor surface is smooth already. If the pads wear a little, they'll fill in the grooves and you should have the same area of rotor surface as new--actually, a tad more.

This is presuming the rotors are not warped forcing the pads to grab--release--grab over and over. That's a different situation that won't correct itself.
