Change rotors?

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 :-(

ok, no rust or grooves. I haven't felt any vibration or wobble when I brake , just heard the squeak.

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!

Or you could wait until it's really loud:

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.

Nanci wins! They made noise, but I just turned the radio volume up.

Next car was a Sentra, and it floored me how easy it was to change the pads. It took more time to find a C-clamp :-(

Thanks for all the good thoughts. Much appreciated!
