There is definitely a safety margin that gives you several thousand miles of normal driving after you hear a brake wear sensor. If you are sure the brake pads are really down to a fraction of a millimeter and want the convenience of scheduling the brake job it might make sense to get the brakes attended to earlier.
I replace the pads myself and always wait for a warning from a sensor. So far I have never had to do anything with the rotors after the first set of pads. There is not a single answer for everybody -- it depends on how how much you value the convenience of knowing your brakes are not going to need work in the near future.
The reason I got interested in this whole brake wear issue is that the service adviser at the Toyota dealer in Delray Beach Florida told me that my brake pads were almost "metal to metal" when my Highlander had its 40,000 mile service. I checked and saw that he was lying. At the 45,000 serve another adviser told me my brakes were nearing the point of needing work, but were still okay (same brakes that were metal to metal 5,000 miles earlier). At the 50,000 mile service I was told that my brakes were so badly worn it wasn't safe for me to drive home and was really pressured me to get the brakes replaced. I was also told that my rear rotors were totally worn out and needed replacing. More lies. I will be going in for my 55,000 mile service next month and wonder what I will be told.
During all of these warning I was told that my 2005 Highlander does not have brake wear sensors -- another lie. Okay, I can look out for myself, but what about people who don't know about cars and can't afford to get a brake job done 15 or 20 thousand miles before it is needed. Several times I have seen women with children crying while waiting in the line to pay the cashier . . . wonder how much money the dealer cheated them out of.

My rear pads have 2mm. Front have 3mm. Should I change them all and ask to feel the rotors for grooves and if there are not too many should I tell the mechs ic to just replace the pads?

I have a new set of Toyota pads in front of me. The new rear pads have a 9.5 mm thick chunk of braking material and the rears 12 mm. So your rear pads have 21% of the original life left and the rears 25%. I can't remember how many miles you have on your Highlander; if it is 50,000 that means you still have more than 10,000 miles left before they are completely gone. So another 5,000 to 7,000 should be safe unless you change your driving habits. Again, the wear senors will warn you when you get close.
You should be able to see and feel the grooves in the rotors through the wheels. It is not so much a matter of how many grooves as how deep they are. The new pads will wear to the shape of the grooves unless they are incredibly deep. In my experience dealers will always recommend resurfacing or replacing rotors. I have never actually seen rotors in a fairly new car -- less than 100,000 miles -- that needed replacing. I'm talking about street cars, not racers.

I have 60k miles. So basically they are ok until the next oil change approx.? What I will do is have the mechanic lift it up in the air and show me all 4 rotors
At that point I will tell him to resurface them or not. I don't do heavy braking which is why I got 60k miles out of them so that's a good sign. When the sensors come on how many mikes do I have left before being in trouble generally? I would rather just change them out and be safe, but what's your thought on it?

You're worrying too much, and making this more difficult than it needs to be.
Change the pads within a week or a couple hundred miles when you start hearing the wear pad sensor. It will sound like a bird chirping.
Do you have any kind of steering wheel vibrations when braking? If so, tell him to turn the rotors. If not, insist that they leave them alone.
My 04 HL has 58K miles, and that's exactly what I'm doing.

So your saying the sensor will come inside my car when its time to change the pads. I understand that part. I just didn't want that to affect the rotors so much if I don't do it in time. I guess my schedule is open now vs later when it night not be ...ao I'm just gonna so it.
I have slight vibration but its barely noticeable.

The wear sensor is actually just a little finger of metal that is designed to touch the rotor when the pad gets nearly worn out. The post that said it sounds like a bird is pretty close -- when the finger touches the rotor it makes a distinctive sound you can hear when you apply the brakes. The sensor is designed so that it doesn't hurt the rotor when it starts its howl, or chirp, or hum . . . or whatever you want to call it.

I see. Well since time isn't on my side I would like to just get it out of the way. Pads at 2-3mn are pretty close to needing replacing anyway. How great is that to drive 60k before the pads need replacing.

Whoever told you that your '05 HL doesn't have brake wear sensors should be fired and barred from working in the auto industry EVER. The sensors are required by federal law, and have been for years.

I was told the same thing a couple of years ago about my '04 FWD Highlander by the dealer in Acton, Massachusetts. They claimed no break wear sensors, and that my pads were metal to metal. Responses in this forum claimed that was a bunch of baloney.
