“High Carbon” rotorson 2014 4Runner

[Catama]

Took my truck into a local Midas shop with a noise in the rear passenger break. 80k miles on the truck and 2nd set of pads. Shop calls back and says it’s metal on metal in the noisy back brake so rotors have to be replaced. Fine. Shop also says front pads need replacement but rotors also because the high-carbon protors get grooved like a record and can’t be turned. This sounds like BS. Anyone out there can confirm that 2014 4Runner has stock high-carbon brakes and they can’t be turned?

My dealer turned all my rotors and replaced the pads at 66k miles about 3 months ago on my 2014. They are working just fine

That doesn't surprise me. That's what I get for going to Midas.

Any shop that won’t turn a rotor or rebuild a caliper should be avoided for any and all maintenance. This is a red flag for a “cant be bothered” attitude and a “replace everything until it stops exhibiting the symptom” with no respect for customer downtime or budget.

They shouldn't just replace it. Someone had to show you the problem and get your okay to proceed with replacement. Tell them you didn't authorize rotor replacement and refuse to pay. Have them put original parts back on if they argue too much. As for myself I'd rather replace my rotors than turning them but I'd most definitely upgrade to such as Stoptech or EBC brand and not some generic store brand that is made cheaply.

No one really rebuilds calipers as a regular repair any more, it's just not cost effective or worth the liability for most shops.

That being said, there isn't a Toyota rotor (with the exception of maybe the Toyota Z4) that can't be turned as long as its within specifications and not hot spotted.

Also have no idea what Toyota uses for rotors never heard of high carbon cast iron rotors

I did see some rotors already ship at minimum thickness. I believe Brembo is one of them, sadly.

Funny, shops tackle many other systems that, if serviced incorrectly, could result in the vehicle stalling in an intersection or losing power assist to brakes or steering. They seem to be okay servicing those systems just fine.

Modern day labor costs make it cheaper to install new calipers (and sell the old ones to be remanufactured) rather than the amount of labor it takes to rebuild them in-shop. That being the case, not worth the liability of installing a part rebuilt in-shop (versus new from manufacturer) just because a costumer prefers the less cost-effective method.

Toyota OEM rotors are so cheap it's often not worth the effort to turn them. My dealer turned mine and within about 10k miles later they were pretty badly warped. Bad pads? Not sure. But they were .012 runout. So they either turned them improperly seated on the lathe or they warped from some combination of crappy pads and/or being cut too thin. Calipers were good, so I'm not sure what the issue resulted from.

But new OEM rotors are only about $75 each. So it's pretty cheap to replace them with new rotors and pads.

Sorry you got taken advantage of by midas. Hopefully they at least put good quality parts in and your good for another 100k.

its generally a good idea to ask for the old parts back. if they are core charge parts than at least ask to see them before they are sent back. most places make you sign a work order prior to beginning work, have them add "customer requires to see old parts before repairs are made". then you at least have a leg to stand on if they do something shady.

typically luxury brand cars have one and done rotors but not a toyota. they should have a minimum thickness spec stamped inside the rotor. make them measure the thickness and show you, if they insist they are too thin.
