Changing Rotors

[Motokid 10+ year member]

Mann, it's been years since i've been here. So instead of my first post back being about audio, it's about brakes

I replaced the brakes on my wifes 2017 Toyota Yaris IA about 5,000 or so miles ago.. Well, i should've replaced her rotors as well but I didn't. Is it fine to go ahead and replace them, or because it's been about 5k miles is it going to cause problems replacing them now without replacing the brakes again since they're supposed to wear together? I am thinking because the brakes are still fairly new it shouldn't cause a problem. Thoughts?

Unless you can't spare the cash I see no reason not to just change the pads as well.

When you change pads you want a clean surfaced rotor some to
Ensure solid bedding. In this case you can put 5k old pads on with new rotors (a clean embedding surface) but unless you bought some 50$ pads just go all new

Yes, you should change the pads if you buy new rotors. Just curious, what makes you think the rotors need replacing?

So the wifes car is only about 2.5 years old and has 60k miles on it. Around the early 50k or so the brakes started squeaking pretty bad.. Mostly in the mornings when the car hasn't been driven or if its raining. Also, if im driving down the freeway and slow down i get a pretty loud hissing noise. So, i spent about $40 on new brakes. Only to find out the pads that came stock literally had half the tread left.. I said screw it, may as well replace them. they were only $40 and i have the tires off.. So i did that.. Still the same result. The rotors are super smooth. They're not torn up or anything. But from what i've read is because they're 'too smooth' and need to be roughened up. I tried taking rough sandpaper to them, didn't seem to help but that's probably because i didn't sand them down enough.. So, at this point, I'm just wondering if the $40 pads i put on 5k miles ago are salvageable. But, it's sounding like I may as well buy new pads and rotors. It's a tiny little car and I can get a brake/rotor kit for liek $100 so I may as well do it.

A lot a brakes squeak after sitting because of condensation, also why you hear it after rain. Also broken anti rattle clips can cause squeaking. If the rotors are glazed over but over all look fine you can take and have them machined. Cheap brakes will almost always be noisy. No watter what don't forget the lube, it helps.

Yeah everything definitely looked pretty sound. However, by the time i buy new pads and have the rotors turned, I may as well have just bought brand new rotors lol. Found some Centric pads/rotors on CarID for about $80. May as well just replace everything since its so cheap. Just sucks I wasted brand new pads lol.

Unless you get the premium centric straying from oem rotors is a meh decision and even if I went
With those I’d use oem pads for a non performance application. Next time go get a free break inspection where they show you what’s wrong. U may have had a funky spot on the rotor that just needed to be surfaced off, pep boys does it for $25 rotor...don’t buy rotors that cost 25$ new.

2017 car needs brakes already? Damn. I got 120k out of my 2010 Focus brakes and 185k on 07 F150.

OEM Brakes were only half used tread, if that. It's the rotors that are are i guess 'glazed' and need to be turned. I'm sure these brakes would definitely last over 100k miles.
