Resurfacing Cross Drilled Rotors

[EmersonHart13]

It is getting towards the time to do brakes on my GXP, it has been a whopping 26k miles and 32 months that I have owned it. I know there are quite a few shops that give you crap about resurfacing cross drilled rotors. Anyone have any luck with places that do? I am thinking that a machine shop would be the better choice.

Do they pulsate?

I just changed my pads and left the rotors they had virtually no wear, surfaces were smooth and they didn't pulsate at all

x2. If you bring it to a shop just have them measure the thickness of them. If they are still pretty thick just change the pads.

I would buy new rotors instead of having cross drilled ones cut.

 

[EmersonHart13]

I would prefer not to waste perfectly good rotors.... I normally agree but the surface seems to be a little wavy and glazed, no vibration though so I am sure I could just sand paper them and put on new pads. But I would prefer to resurface them to basically start fresh.

 

[Bob Kazamakis]

Then see what the local machine shop says. I'm sure they'd be able to take off a very minimum amount. I usually go to napa.

 

[EmersonHart13]

That is the plan, I do not know of anyone that has actually had it done although people on forums all over say they have.

Carquest says they will give it a try. Sweet.

I would not try to do this on any type of brake lathe. most places that do normal brake rotor turning will not do it anyway. These need to be done on a milling machine. slotted rotors even more so. They need to be machined as you would when you resurface a flywheel. not sure what equipment carquest has, but good luck.

 

[EmersonHart13]

They have a full machine shop, so they might have exactly what you are describing.

 

[Bad00SS]

you should be all good then.

 

[EmersonHart13]

And that would explain why most locations turn this down.

Good info here. Thanks everyone.

Little Update:

Dropped them off at the Carquest machine shop this morning at about 8:15 and went back to pick them up at 5:15 and they weren't done. Apparently it took him all day to turn 1 and a half rotors so he expects to have them done by lunch tomorrow. It takes many passes to do it properly so it is time consuming!

 

[Riski]

Hope he gave you a flat rate and not a hourly rate

 

[EmersonHart13]

Me too, otherwise I won't be picking them up! Actually I don't think they were on the lathe all day because something tells me eventhough I was there shortly after 8 there was probably a few things in the queue before me.

For comparison new rotors from Carquest are 120ish each.

 

[Riski]

So you dont have a clue what he is charging you?

You might wanna give him a call and ask, so that way you can order some new ones QUICKLY

 

[EmersonHart13]

They have the new ones in stock on the shelf. I know the normal rate for resurfacing (like 10 bucks), I get all my rotors done there so he would have told me if it was different.

 

[Fish]

Napa premium rotors are $46 each for the fronts for your car. I run them now and I think these along with the EBC pads were better then my old crossdrilled/slotted rotors and pad setup.

 

[EmersonHart13]

I know you can get non cross for lower, I was citing the comparable replacement. I chose to go with Akebono pads as I am not happy with the stockers, lots of dust! Also they were barely able to cut the rotors, after 25K miles the pads were totally gone and the rotors were just about at the no cut zone.

 

[Fish]

Just saying for next time. I saw no difference in normal driving between drilled/slotted and blank rotors.

 

[Bob Kazamakis]

I had napa gold rotors and hawk hps pads on the Gp. The hawks ate them up in about a year.

Shitty autozone rotors with lifetime warranty ftw.

 

[EmersonHart13]

I was going to buy Hawks but I heard great reviews on these pads so gave them a whirl.

And yeah I might switch at the next change because yeah I am pretty sure cross drilled is all for looks. But it does look nice.

Well you shouldn't under normal driving. Drilled and slotted are for racing, blank rotors would actually work better for normal driving since the rotor has more surface area.

Agreed. For the most part. Drilled is for show. Slotted is useful in high heat situations.

You think? I've heard that drilled has its pros under high heat situations also. Just think it'd be weird for BMW and Chevy to use drilled rotors for their high performance cars just for show.

 

[Bob Kazamakis]

Just my opinion honestly.
