Default 1999 Brakes

Hi, I have a question, hopefully not to stupid. I need my brakes redone, and the rotors definitely need to be turned. Should I get them turned or buy new rotors? Also, I know pads are easy to do, but, how hard are the rotors to replace on a Vette?

Turning rotors makes them thinner and more susceptible to warping a second time. Just get a set of new ones and stick them on. Installing rotors on the C5 is very easy.

Agreed - wouldn't recommend turning them. I've had good luck with ATE rotors from Tire Rack; $48ea fronts, $43ea rears. They're slotted, and the slots are cut at the minimum rotor thickness, so you can tell whether your rotors need replacing at a glance without putting calipers on them. I've used them for regular driving, and HPDE days at the track, and never had a problem.

To replace pads, you just need to remove one of the caliper slide bolts and pivot the caliper to remove and replace. To replace rotors, you need to remove the caliper mounting bolts. These are on there pretty tight (I forget the torque spec), and you'll probably need a breaker bar to get enough leverage, but it's only 2 bolts per caliper. The manual recommends replacing the mounting bolts when you remove them; I didn't, but used high-temp thread-locker.

Good luck.

That sounds do-able. After the calipers are off, is there anything holding the rotors on. or do they just slide off?
Thanks for the recommendation for rotors as well, appreciate it!

The caliper mounting bolts (slide pin bolts) are small and only torqued to 23 ft lbs. After the calipers are off the caliper mounting bracket has the two larger bolts that are torqued to 125 ft lbs. After both the calipers and brackets are off the rotors are free to be removed/replaced. You'll also need a spreader to push the caliper cylinders back to make room for the new pads to fit over the new rotors. Watch your brake master cylinder reservoir when you are compressing the caliper cylinders so that it doesn't overflow into your engine compartment. All basic stuff - go for it.

If the rotors have never been replaced, there should be some thin retaining clips on a couple of the wheel studs, but all you do to remove the rotors is pull. It's not a hard job; if you're using a floor jack and jack stands, it'll probably take you longer to raise and lower the car than to replace the pads and rotors!

The rotors are safe down to the minimum allowable thickness stated in the service manual. I run mine down to this thickness regularly before replacing them without issues.
It's your money, you are welcome to spend it unnecessarily if you desire.

Ok, heres the million dollar question for those of you with a lot more experiece with Vettes than I. Would you have the rotors turned ( if still thick enough), and new pads for $244. Or, buy new rotors and pads for around $100 more and do it yourself?

If you're just going to replace the rotors with stock,you might as well use them till they're used up,IMO
