Can RAV4 Rear Brake Rotors be turned?

Hello everyone,

Apparently I have been very lucky. After a little over 116,000 miles, the rear brakes on my 2007 RAV4 (V6 Sport) are finished. That's right. over 116,000 miles on the original rear brakes. Shouldn't I get some kind of recognition award from Toyota for this?

The customer service representative at the place where I usually have work completed on this vehicle told me that you cannot turn these rear rotors. I had to buy new ones. I've never heard of this other than if one is to be so negligent as to wait way too long so as to have a metal-to-metal situation.

I inquired of my rep: Does this mean that if these new pads and rotors that are being installed wear out in, say 60,000 miles will I have to buy new rotors at that time again? His answer was a reluctant yes. Reluctant because he knew I didn't want to hear that answer.

I'm posting to this forum looking for some confirmation. Was I taken by the place I had this rear break work done (btw: this was a very reputable national tire franchise operation. I like em. I've purchased two sets of tires from these folks for this vehicle so far) or is it in fact true: you cannot turn rear brake rotors on the RAV4?

Thanks to all for your time in responding.

Rotors may always be turned if they are still above minimum thickness and are not warped.
They may not even need turning.

I agree with Rich - and many brake shops have reputations for telling customers that brake rotors need replacement when replacement is not necessary, a tactic to increase their financial bottom lines.

Unless you are installing them yourself you are taking a chance of them warping due to the thinner thickness and paying for labour a second time. In the past rotors where much thicker and could be turn in some cases a few times but now rotors are considered disposable.

Thatís exactly my experience from my apprenticeship. Rotors these days are quite thin. If the pads need replacement, the rotors will also be worn. There is a specified minimum usage thickness AND a minimum required thickness to allow turning, as some material is lost in the process. These numbers are typically stamped on the rotors somewhere. If youíre at or just below the minimum machining thickness you can roll the dice and use the rotors as-is with new pads but this is NOT AT ALL RECOMMEND!!! Honestly as long as you buy coated rotors (rust resistance) the price is reasonable. Besides, the cost to have a shop machine them is close to the price of replacements. Why spend close to the same for less rotor?

You don't mention when the fronts were done and what was done with the rotors. I agree with those on here that say replace, don't machine them.
116k is a long time for brakes. You might want to have the brake system checked to see if the rears are even working.
Brakes are one area you don't want to economize on.

Agree on don't cheap out even on rears. Turning them removes metal which is the heat dissipation basis. If you're paying labor for the job and turning them i think you won't see half the life you saw before. They will warp and you will be redoing soon. Not as prominent on rear vs. Front but still. My $0.02 worth..

You most certainly can have the rear rotors turned. Had my rear pads replaced and rotors turned a week ago. 80,000 miles.

Again it depends on the remaining thickness. If itís more than the minimum refinishing spec stamped on the rotor, go for it. If less then youíre at new rotors. Still depends on what youíll be charged for new rotors vs turning your existing ones.

I think the OP was asking if they can be turned at all, regardless of thickness, as he was told the rotors HAVE to be replaced regardless of the thickness of the rotor that is left.
