rotor damage? opinions?

ajc1884 · 04-18-2013, 11:50 AM

So i decided to look at my rotors today, just because.
When i bought the car i didnt think to even look at them. (no need i thought because the brakes werent making noises and felt fine.)
So my front left, and both rears look and feel smooth. The front right is smooth except for a probably 1/16'' wide score mark that goes around the entire rotor !!!!!!!

2009 w/ 36400 K

What caused it? Will it pass inspection?
Probably happened before i bought the car, right...cause i havent heard or felt anything going on with the brakes since i bought it

Probably a rock or something getting caught. 36,400k miles for rotors isn't all that bad to be honest. If your pad look like they need replacing soon, it might be a good idea to just upgrade rotors and new pads at once. It's a surprisingly easy DIY if you have some basic mechanical skills. If the gouge is deep, I'd replace it regardless of passing inspection.

In all honesty, agreed!

As has been mentioned already, it was probably caused by a rock or some other material. There is a radial groove in the pads that can fill up with mud - happened to me and I chewed up a rotor - make sure it is clean.

How serious it is depends on how deep it is and how wide. If you haven't felt it, it may not be as bad as it looks. You should be able to find some pics of good vs bad rotors on the Web to give you some idea of what you are dealing with.

Go to a brake shop that you trust and ask for their opinion. If it's a minor scratch, they should be able to turn the disc and get rid of it. If it's too deep/wide to repair, I'm sure they will be glad to sell you new rotors/pads.

To echo what's been said above, it might be time to get new rotors/pads all around - the brake shop should be able to help with that decision. Upgrade if wanted.

Perfect excuse to upgrade to slotted or cross-drilled rotors OP
