Earlier this year, I noticed my brakes starting to screech (especially in the morning or when it was cold out). Not the distinctive squeal of finished brake pads, but the more "grinding" screech of smoothed-over pads and rotors. Sure enough, upon inspection it appeared that the rotors were quite shiny and overly smooth, and the pads, while they still had a fair amount of meat left on them, were quite glazed over as well.
So I picked up some new pads, and we made to change them out and get the rotors turned (AKA "lathed", resurfaced, etc.). But then... well, let's just say "life happened", and we were unable to complete the entire job on one occasion, and only got the new pads on without having the rotors turned.
Three months later... we are finally in a position to finish the job up. But now the question arises: SHOULD we still get the rotors turned, and use them with the semi-old pads now? I haven't put THAT much mileage on them since changing the pads, mostly just drive around town, I'd say around, oh, 3,000 miles or so. I've got conflicting opinions here on whether or not it'd be a good idea. One family member says it'd be fine. Another looks at me like I'm crazy for even suggesting the notion of having the rotors resurfaced and reunited with even the slightest of used pads.
I don't much want to go and pay another $60 for brand new pads again just three months after already doing so, but I don't want to keep putting off the full task either. And yet, I don't want to screw anything up or risk any worse possibilities. So I'd really appreciate some professional/experienced insight and advice here! What do folks here in the auto field think?
Thank you!
(A side-question: Should I take my rear brake drums to be turned without changing the shoes? I've noticed a bit of noise back there too. How often should brake drum shoes be replaced? The last I did them was March 2011, and I don't think the drums were turned at that time.)
