Just thought I would share a pic of the rotor pile where we keep our scrap. This is about 2 weeks worth eek

So that's where you and the others take your "breaks" at work?

I'm so Damn old, I was trained to turn both rotors and drums in college automotive technology courses.

This reminds me of the pile of rotors my wife's previous Sebring ate over the years.
Eventually I gave up any reasonable service strategy and experimented with different brands until,
shockingly I finally found one that held up.

So wasteful to just throw the stuff out when there's a slight issue, but no other choice.

autozone brand is pretty good, full 2 year warranty or the coated rotor with a 3 year warranty..as for cutting, that trade is lost..not many know how or even have the machine

At one dealership where I worked, the lot man would make a trip to the local scrap dealer when the piles go too big. The service manager bought us all lunch with the proceeds.

the dealership i work at USED to do this 10+ years ago.
there is a scrap metal dumpster behind the shop now. it usually gets filled up and hauled away every month. the $$$ go to the owners now.
most dealerships and larger repair shops do it this way now.


perception is 90% of reality

Reputable shops still service the original rotors and drums VS. jumping on the 'scrap metal' train.

The last two times I had my rotors replaced at my Dodge dealer they WOULD NOT turn them, only replace with new. It seems that ALL the manufacturers recommend the same thing, so what has changed? People complaining too much about warped rotors 6 months after they are turned? work Chinese steel sucks so much that they cannot be turned reliably? Cheap wheel bearings failing so they MUST replace them also? work


The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

The last time I bought rotors for the Ramcharger I had them mic the new ones since they already had the mic out to check the old ones, they were just a few thousands over the minimum to be turned. IMHO, just the wear from one set of brake pads lifespan will take the rotor under the minimum specification to be turned.

A lot more issues with rotor rot than rotor thickness

It’s less expensive to put on new Chinese rotors.


China is the enemy.

Its all a big hustle for the people who cant turn a wrench, I average 130-150k miles off oem rotors with simple pad changes and light da scuffing on the rotors then and simply drive like ive got some sense.

I am at 111k miles on the OEM rotors and pads for the work truck.

Got over 90k on the OEM tires.

I have a pair of brake drums off of a 44,000 mile truck. The shoes looked great, but the chassis was going under something else, so the owner wanted new shoes and wheel cylinders. One rear drum had a little warp and created a noise at slow stopping speeds. Took the drum in to get turned, only one of 6 parts stores in town turns drums now. and then only one guy. The drums only have .060 that they can be turned (even new off the shelf), The 1st cut only cut about 1/4 of the drum. The 2nd cut cleaned up about 3/4 of the drum, The 3rd cut cleaned up the entire braking surface, but that cut was not smooth. The guy took one more small cut to try to clean up the surface, after he replaced the cutting tool. It was just slightly better, but I took it home, it was just under specs. The guy did not charge me to turn that drum ($20 normal cost). My cost on a replacement drum was $60 (the local store was cheaper then what was available on line right at the time), but would have had to be ordered. Before Dec I priced out those drums and they were only $42 each then, but the week later the price jumped to $60. The front rotors only have an allowable .060 cut as well, try getting a warp out of a rotor in a .060 cut once, at .060, you would be lucky to get a smooth cut on both sides from a rotor that wasn't warped. By the way, its cheaper these days to buy a rotor kit, (both rotors, and pads), then it is to buy just rotors. You can get the master front brake kit that included calipers and hardware as well as the rotors and pads for less the the calipers and the rotor kits separately.

If the brake noise come back, the customer gets new drums, at whatever they cost then. I spent a couple hours jacking with that drum for a questionable return. Would have been more cost effective to order the new drums before the project started.

Here is why I think manufactures now don't turn brake rotors and brake drums because of liability. I know from having to do brake certification for on-highway motorcycles for a manufacture one of the requirements for NHTSA/FMVSS is that brake fluid reservoirs must maintain or have in them 15% more brake fluid if the brake disc or drum is at the minimum thickness or the drum to its maximum wear limit. Then with the brake pads or shoe material completely gone still the plus 15% remaining fluid in the reservoir. Think about when bleeding your brakes how you have to constantly top off the reservoir as you're doing it. All it takes is one mechanic to over turn a brake disc or drum, a set of well worn brake pads or shoes and someone forgot to top off the reservoir and a claim of brake failure, lawyers and expert witnesses measuring things and someone is going for the deepest pocket. So even the national service shops put the brakes (pun) on turning brake discs and brake drums to avoid any liabilities. You can still find or even buy brake turning machines but you won't find major shops or dealerships that will do them it's the way it has been. You can do it yourself as far as turning the discs but you'll probably find it cheaper and quicker to just buy some good non-China brake discs and drums the next time.

Here is what usually happens in our shop. The car is in the lube bay and they notice the brakes are worn under 4 mm. The writer sells the job with rotors because they don't trust the lube guys ability to judge the condition of the rotors. I don't machine a lot of rotors anymore maybe 1 or 2 sets a week. I look at it this way they only pay me 1.8 to machine rotors,replace pads,and service the arbors and pins. The pay me 1.5 to replace the rotors,pads and service the arbors and pins shruggy So is it worth it for me to set up the lathe and machine some rusted rotors for 0.3 ?

The customer has no say in the decision?
