My all trac needs new rotors.. should I go ahead and get them resurfaced if they have enough "meat" left on them?

usually how long do resurfaced rotors last? are their any drawbacks?

should I just go with new oem rotors?

With each resurfacing, metal is removed, leaving you with less material to absorb and dissipate heat. Any heat related issues you had with the original rotor surface will return. And it will happen more quickly than it did when the rotors were at full thickness.

Before I make the decision to replace or turn the rotors, I price new rotors first. Sometimes it is not much more $ to buy new, though I find many aftermarket rotors to be junk. On my work trucks/vans, I usually buy OEM.

if new rotors are 25 bucks, and it costs 6 bucks to turn, i'd buy new ones. this is likely the case if you have rotors that slip on over the hub. the integrated hub/rotor ones tend to be more expensive though

Get new rotors, properly bed in new pads, and you'll be happy for years to come. Turning rotors is not as apocalyptic as some think, but it does tend to increase the chance for cementite inclusions in the new thinnner casting.

There are three basic methods for machining rotors: 1- the "turning" method which basically turns your rotors into an LP record, 2- blanchard grinding which is the most common way that new rotors are finished, and 3- machined and peened. M&P rotors look like they've been media blasted, but their finish is far less likely to capture and hold pad material. The first few miles will have some noise, but its worth it. Bed them in hard and drive it forever.

My brakes pads have less then 7k miles on them...

they are hawk hps..

I know I messed up, but when I installed them, I did so without resurfacing the old rotors...

If I get the rotors replaced or resurfaced will I be able to use the same pads?

Yeah, you'll be able to use the same pads. You might want to make sure there isn't any weird wear going on with them, though.

If you have the money to buy new rotors, i'd just do it. But... being that i have the little brother to your car, i also know how stupidly expensive rotors are for these damn things, so that's entirely up to you. If you're going to be racing the sucker anytime soon, replace them. If it's really just DD duties, just resurface.

I just resurfaced mine, since it won't see anything more intense than a couple autocrosses through the rest of the season.
