I have a 2013 Ford F150, 46K miles, needs to brake pads. The rotors look ok, no rust or grooves. I haven't felt any vibration or wobble when I brake, just heard the squeak.
Question: How do you know when it make sense to change the rotors in addition to the pads?
FWIW -- when I was too busy to deal with the problem, the ('69 LTD) pads wore down to the backing plates, which dug interesting grooves in the rotors -- the deepest of which was 1/4" or so. Until they started hogging in and I HAD to replace them they stopped just fine :-(

tion to the pads?
I never replace the rotors unless it's deeply scored. If it's lightly score d, you just reface them. The quality of rotor work varies immensely. The on e I got from the chain store looked like it was done by a 12 year old that was playing Pokemon Go while on the lathe. I took my rotors to a little sha ck in a scary industrial area. It was a real hole-in-the-wall but the guy d id beautiful work. The surface looked like a DVD. Cheap too. Mamma Mia!
No rust, hot spots, tapered wear or cracks. VERY light scoring is OK. Might hit them with a scuff pad and some brake cleaner after measuring them for thickness and install the new pads. Then go for a short drive and seat the new pads.
Anything else and they get cut (if they are thick enough, many newer ones are not) or replaced.
