What's up Maxima.org,

I'm kind of in the market for some new rotors/pads and I've considered some different setups.

Now I have the opportunity to grab some low mileage, drilled/slotted brake rotors off of my buddy's Maxima which was totalled. They were in great condition but they've sat for awhile and they look rusty and I'm wondering if they can be resurfaced/repaired.

Below is a picture let me know what you guys think.




Thanks,

If you just drive them, the heat and rubbing of the pads should burn off the rust I'd imagine. I don't see why it'd be any different than when your rotors rust over when sitting in wet weather. The only thing I'd be consider being worried about is the drills cracking.

 

Get a DA with a flap wheel to grind off some of the rust. Or a die grinder with a wire brush. Or a drill with a wire brush.

 

i think you'll be okay. The only thing i be'd worried about is it cracking.

 

Good call on the wire brush. Just be careful you don't push too hard or you might cause an uneven surface.

And you'd probably have to pay big money to get them lathed. Most shops won't touch cd/s rotors because they eat up lathe bits like no other.

 

Thanks for the advice guys. Is there any insight on shops/places that can do this for me on drilled/slotted rotors?

 

Just check your local shops. Some may turn them for you. Your best bet would be to try driving them first. If they're warped, then have them turned. The rust may just wear clean. If they've already been turned before, and you turn them again, it may throw them out of spec and make them useless.

 

wirebrush or sandpaper

 

Okay. If I do buy them I'll install them and ask around and see if I can have them turned, and make any decisions after.

 

Can be used but

Have they been machined or turned, if so how many miles in total on them?

When the Rotors get to less then a certain thickness they are junk

 

I agree with DrunkieTheBear, if you wanna use em make sure they're thick enough. Most rotor companies stamp a minimum spec on the rotor. I'm a little concerned with how crappy they look. Personally I wouldn't put those rotors on my car...and when a car comes into the shop for brake nosies/pulsations with a rotor looking like that I wouldn't even machine it, I'd recommend replacement.

 

how can i tell which drilled an slotted rotors will crack an which wont?

 

Drunkie, you're right.

the rotors have less than 3k on them. But ill probably just get blanks w.Axxis/Hawk pads just because they'll be cheaper than these are. The cracking worries me especially seeing as how I don't wanna have to keep replacing them.

 

What I dont get is even if they have room to be machined, why would you run them? There old as **** and rusty as ****. This is your brakes where talking about here, Dont be cheep if you want slotted just buy some new rotors. I work for a big company on the west coast called Les Schwab, we do brakes. I have seen rotors brake and sometimes the result its not prity.

 

Really? My rotors brake all the time, and it's totally great.

Haha... in all seriousness, though, those are not going to be as sturdy as blanks due to the slots and holes, and that rust looks pretty bad. How long have they been off the car? Rust likes to spread through something. If you're just leaving them in the rain overnight, it builds up a thin layer of rust, but you can still see the metal underneath, and it's a lighter orange. That's a dark brown, the surface looks rough, and it completely covers it, with no metal visible. The holes and slots are rusted, so probably the venting and metal inside is rusted too.
