so it is about that time... my pads are almost to the point of changing, except i have slotted rotors on the car... was wondering if anyone has found a place that actually turns slotted rotors??? is the process any different or just a special machine???

or am i just doomed and should change to back to regular rotors?

 

Most places out here wont turn them you may want to call around because my friend went to a place that did turn them, I think every shop may be different.

 

I used to turn slotted rotors all the time when i worked at o'reilly auto parts. It's the same process as a non-slotted rotor, the blade will just skip over the slot. The only thing that might be an issue is that it may put more wear on the blade. But even that is probably minimal.

 

Acura North Scottsdale's service department has turned mine without a problem; not that you're in Arizona, but if this dealer can do it, can others?

 

I've only found one shop in my town that would do it. It took me going to several different shops and asking. This is what you need to do. Good luck.

 

are you getting any sort of shimmy or anything from the rotors? If not, there is no need to turn them and unnecessarily make them thinner.

FYI slotted and cross-drilled rotors can be turned, however they just wear down the blade a LOT more on the lathes that do the work. Also your slots will probably be a bit "worn down" and your brakes won't have as much grab/bite to them

 

Hmm... This makes me second guess getting slotted or cross drilled rotors. Thanks for bringing this up. I'll have to do some research on this.

 

just remember a well designed slotted and/or cross drilled rotor won't warp and thus not have the need to be turned! It is not necessary to turn rotors when changing pads!

Stick with a reputable brand that has some science behind their products such as Racing Brake and stoptech who's internal structure is made differently for better cooling.

 

Makes sense. Thanks. Are you implying that the OP has cheap rotors

 

Although I personally completely agree with what you said (had drilled rotors on my Accord for 60k miles zero warping issue, never once had them turned), there's going to be a host of people that disagree with us.

Even non-slotted rotors don't need to be turned every time you change brake pads. If there's no pulsing when changing pads a new pad set and a good cleaning of the rotor with brake cleaner and a clean rag will do the job. And of course proper pad break-in.

 

Maybe

If the rotors are well designed they shouldn't warp unless you are going WAY out of their design like tracking them or doing repeated triple digit stops.

I mean take for example my Racing Brake rotors on my TL, I've stopped from 110-55 quickly then 2 minutes later from 130 to 55 and the only thing that happened was a bad smell from all the gas being dumped by the catalysts. The brakes performed without a hiccup! I doubt my stock rotors could have even survived the first braking session without warping...

But like I said before, new pads do NOT mean you need new rotors or need to turn them. New rotors are needed when either A) your old ones do NOT meet minimum specs or B) your rotors cannot fufill your needs or C) they are warped. Rotors should ONLY be turned if A) you are getting a shimmy while braking, B) the new pads are not touching the rotor properly due to an excessive lip at the edge of the rotor from different old pads.

 

Not sure if mine are cheap but def not eBay rotors... I have slotted rotoras on the 1g tl for about 4 yrs now and started to feel a slight shimmy during braking a few nights ago... I have also noticed some slight squealing during slow speeds but the pads still look good... Maybe some brake dust just needs to be cleaned and the pad clips needs to be regreased... I'll give that a try first before having the rotors measured...

 

I do know that they have to be turned a little bit slower than normal ones. I beleive it's to keep the temp down when turning it. It's been 15 years since i had cross drilled on any of my cars. I had stop tech back then and they were amazing rotors.

 

it is so hard to find good oem replacement rotors nowadays with the cheap china and ebay crap... even some of the reputable manufacturers have sent production overseas... but i guess anything is better than the Honda/Acura rotors which warp if you just look at them incorrectly...
