Default Brake Pads and Roters

So I just read some wheres to never turn your rotors.. Why is that? What happens if you do?

Where is a good place online to buy OEM Roters and pads for a good deal?

Also.. Is it bad just to do the rear brakes and not the front.. The front still has a lot of pad left.. It must have been done before I owned the car..

I was about to do my brakes and I was going to have them turned I'm kind of bumbed that I have to buy new rotors.. The shop said that they could turn them for me..

People avoid turning because after you turn them, they are thinner than before and will just warp even faster than they did the first time. Some people feel the difference in price between buying new rotors and having them turned doesn't justify the reduction in longevity you get out of turned rotors.

Personally I prefer to buy new rotors rather than turn them.

I agree that replacement is better in the long run; turning the rotors is a short term fix.

Is it safe to get them turned if I plan to buy drilled rotors in less then a year? I've had the car for 2 years and still have alot of break on my front..

If I had to by rear pads at Kregens what pads should I get?

^ you'll be fine.

and to mikeabtin, you can just buy cheap rear pads and install them. you don't have to turn the rotors unless you already have vibration. and if you did, it's probably better to buy new rotors anyway.

napa rotors ftw. $42 each for the front. less than that for the rears.

^ if there are no grooves i would say that you don't nned to turn them, but do scuff them to get the glaze off. if there are grooves then have them turned, or they will prolly squeak. you don't really need to worry about warping the rears cause they don't do as much or the stopping.

even on the fronts we almost always turned the old ones if they were thick enough. if they are within .08 inches of discard you might as well get new ones though, cause they will be so thin that they are bound to warp after machining them.

oh and as far as i know, you can not turn drilled or slotted rotors, so unless you have a habbit of warpping rotors i would strongly suggest that you don't get them. unless of course you plan to track more often than most people.

and you don't need to do the fronts at the same time as the rears unless they need it.

and remember to open the bleader when you compact the piston. a couple cents for the amount or brake fluid you loose is far better than a new master.

Back when S2000 rotors cost around $100 each, I turned them. If the machinist knows what they are doing, it's fine.

At $45 per rotor (or less) it's less worthwhile. Plus, most shops around here no longer perform this service, claiming liability issues.
