My GS with TRD slotted rotors vibrates like mad when I brake at highway speeds. I just had new tires put on and they told me my brake pads are full of life. They said they could not resurface my rotors because they are slotted.

I really do not want to spend the money on new rotors, especially since these only have like 20K miles on them. Not only that, but then I would need to get new pads at the same time (recommended I believe). Can anyone shed some light on this for me?

 

I am not sure the answer to this question but I can tell you that I bought a set of cross drilled AND slotted rotors adn they came warped so my buddie at his shop resurfaced the rotors. I never put them on because the company sent me new ones but my buddie said they were shaved and they would be like new. Hope this helps?

 

I've also had my slotted & drilled rotors resurfaced... I'd assume that they can do just slotted with the right equipment.

 

I had the same problem as well. I inspected the rotors and they were not warped. In fact in order to warp the rotors you gotta try really hard. You could have a rotor that has an unusually hot spot (and therefore grips really hard there). I did notice that after I changed my brake lines, the shimmy/shake resolved. I did not have the rotors resurfaced, just the brake line changed (I used the SS lines). Maybe the flexion/expansion of the brake fluid in the lines is causing weird braking pressures. If you are thinking about getting the SS lines, I would try this first. Then possibly get rotors if the problem is not resolved.

 

Most shops won't attempt to resurface slotted or drilled rotors because it requires a stronger 'bit' for cutting on the lathe. (At least that is my understanding.) You will need to find a performance shop to do them.

You may also want to check with some dealers, like Nissan, that offer Brembo brake packages as stock options. Maybe a Porsche shop? Pricey!?

I had to try three different cobminations of rotors and pads before mine settled down. I was going through them every 6 months. Good luck.

 

I have resurfaced 3 sets of x-drilled/slotted rotors. Any machine shops with carbide bits can do the job.
It costs me $35 for both SupraTT front rotors.

 

Depends... My local Lexus dealer (recently went through a shop upgrade) had the correct equipment to resurface my cross-drilled / slotted rotors. Also pricey, but I prefer they work on it.

 

Any shop that can properly surface standard rotors can easily surface slotted/ drilled rotors. Had a lathe myself till I sold it last year
Always turned them myself. No special bits needed. No premature wear on the bits over the ordinary usage.
