While putting new brake pads this evening on I saw this:



This is at my rear passenger corner

My rotors have no cracks, using a digital caliper my rotors are almost new based on their thickness

...what is it and do I need a new one? Is that part of my hub? If the whole thing cracks apart would I lose my right rear wheel? Lol I drive in the canyons a lot now I'm paranoid

Pls halp corvetteforum

CHEV AGAIN

That is the rotor, your E- Brake drum is inside. A new rotor is about 80 bucks at your auto parts store. No biggie at all. I would do both rears and pads. It could be a casting flaw, a better look at the inside is needed.

Thank you Mark, I just put the pads on it took me literally 6-8 minutes per corner so I can do it again no problem

I believe I can drop the rotor off very easily once the caliper and caliper brackets are off, and then maybe bring it to a shop to inspect its inside to see if it needs to be replaced completely?

I have the Z51 rotors so dunno if my local autoparts store carries them. I know the drilled rotors tend to crack more on the track so I don't mind non-drilled rear rotors, but then my new rear rotors won't match my fronts

CHEV AGAIN

They'll have em, if not they can have them in a couple days. If when you get them off and there's a crack on the inside too it's junk. It should be easy to tell a crack from a casting issue.

I called my local dealer for a price on rotors and pads, their price was $1400.00!

Wow. I just got all four corners of Hawks HPS pads brand new sealed in box for $173 shipped and installed them myself for free

Ugh my rotors are almost new why the hell is the right rear corner cracked

That was their wish for rotors and all. Needless to say I got them all for a little more than 400.

Wow awesome $1000 leftover for headers heh

It's cracked replace it. Maybe dealer will replace under warranty. Either way get a new one. IMO

Are those the original rotors or aftermarket?

thedigitel

That's just a casting mark, pull them off and look at the inside to be sure. I bought a set of z51 rear rotors that look similar. Shop said no big deal, normal.

ErnieN85

no it is not that needs a new one
fix it before it breaks, cheaper than a wreck

Get the welder and grinder out/

I got the car used so not sure...but should be factory

Would it be fine to run a set of new rear rotors and keep the old front rotors? Folks don't usually replace all four rotors at the same time do they?

trying2seek

Cheap insurance to replace both back rotors..

BWF07

Sure you can replace just the back rotors with out any issues. In fact you can just replace one if you want. Many times one rotor will be beyond it tolerance for turning and they will replace just that one rotor. I suggest that you replace it with the Z51 rotor as that is what it appears you have. Does your car have the Z51 performance option?

It would be best to replace both rear, just to have the best possible balanced braking on the rear. You could do just the one to get by, but I would do both.

might be a warranty issue. Doesn't matter if you're the first owner or not. Have the dealer run the vin to find out.

furiousox

Yep it's a Z51 car

Yeah heavily leaning toward replacing both but having trouble trusting Autozone's brand Mainly due to lack of reviews. Similar story with eBay / Amazon brands. I don't track my car (yet) but I drive in the canyons quite a bit, though I'm not very hard on the brakes there as I usually engine brake into corners.

Also don't want to buy rotors that are too crazy like the DBA and KNS ones since I might sell the car in the next few months...

My car has long been out of warranty Thanks though I wish warranty could cover this

That rotor REQUIRES immediate relacement, do not pass Go do not collect $200!
