The best reason for being able to turn rotors is to save hoist time. That was always the best sales pitch for having a brake lathe. The last thing you want is a hoist tied up all day for a brake job the could be done in an hour or two.
I plugged that scan too in my friends chevy and it laughed at me. I looked up the code and it said YOU SHOULDN'T HAVE BOUGHT A CHEVY. hahahaha The other code said the class action letter will arrive in 7-10 business days.
Half the "new" rotors out there are garbage' of the hot variety. I would turn my factory rotors until you could read thru them before i strap on a set of amazonian unobtanium based replacements.
Cutting rotors also weakens rotors. Most average Joe cars buying new rotors are cheaper than turning them down. Sears use to try and pull that saying need your rotors turned then hit you with a 70 dollars a rotor price. On the same car get new rotors for 78.99 so yeah would go new over turned. Always gotta weigh pros and cons though. Great informal video Brian keep up the great content :)
On my truck they cost 115$ per unit. If you calculate the low milage i do and i dont haul anything more than my 4 wheel in the truck... How much he said? 180$? Its a dam good deal!!!
@@jean-michelb7290 Good deal to save 45 bux while weakening and thinning your rotor? Makes no sense. For 225 you will have brand new units with warranty - just bring them back to autozone if they warp again.
Cutting the rotor is producing all kinds of metallic dust and that guy just shoves his face in the cloud with no respirator. He's going to be dead long before his time.
Nicely done matey. Nothing wrong with cleaning them up on the lathe, so long as there in spec. Plus if ya cant get new ones you will have to turn them !!
So glad to see ZZ Toptech wearing safety glasses. Rotors will blind you. That's a crazy cheap analyzer. Anything it doesn't do. Can you tune through it like an N guage?
@@PIPSBURGHVIEWS okay, surprised my university professors didn’t tell me about this lathe. Anyways Thanks Brian. Watching your videos are better than being in my university online class.
It does shorten the life span minimally but you will have better brake feel and pad contact. I will see what I can do on a flush but I don't do those very often.
I watched this because I have a very rare 40-year old collector car, and rusty NOS rotors that must be turned before installation. The kerfuffle about turning them on the car for warranty work is irrelevant to me. It's a minicar with 8" rotors. Will machine shops be able to handle such small ones?
Never turn your brake discs that way. 1 No warranty 2 Brake discs become skewed, they may hit a maximum of 0.05 mm 3. You get easily below the minium thickness and so on
All new car manufacturers require the tech to attempt to cut your rotors before they will pay for new ones. If your car is still under the brake warranty, this will be done for free.
@@PIPSBURGHVIEWS Okay maybe in USA but not i EU. Brake disc toIerance on Runout are 0,050 mm and when the disc are on the car are the tolerance 0,1 mm. I have been working with Quality on brake disc for mere than 25 years.. In Denmark
Jacob -- I have machined rotors for 57 years & never an issue. Legally when your in a business then min thickness is an issue. If you take your rotors to an auto parts store & they go under there is no issue IF it is your vehicle & you install New Pads to regain some caliper space.
As a tech your selling your labor. Do the math on every job. If the rotor is available and cheap dont bother. If its pricey turn it. The second good reason is hoist time. Nobody wants a hoist tied up all day waiting on parts. Pads and shoes are widely available. Rotors are another story. Your way better over time if you have the option to turn them when it saves you the hoist time.
@@PIPSBURGHVIEWS so how come the manufacturer prefers the on car method? Seems like the bench will be a more even cut. Sorry for all the questions lol 😆
Most of them are covered in a light oil for corrosion protection which needs to be cleaned off before you can put them on, other than that they are good to go.
@@PIPSBURGHVIEWS all rotors should be checked for runout when installed, and corrected if above mfr spec. This is to prevent the development of thickness variation and pedal pulsation.

I did but it depends on the shop labor rate. We would get paid 1 hour labor to replace rotors or 2 hours to cut them. Keep in mind, the cheapest OEM Subaru rotor is now $165. So, if you replaced just two rotors, you would be looking at $420 for parts and labor. Now, if you took the rotors off yourself and took them to the parts store for cutting, it would be substantially cheaper. Thanks for watching.
Im guessing because this video is 2 years old. You can buy 4 new rotors for under 200$ pretty much everywhere nowadays.. So this must be a lost art. For those who can afford a higher end brake rotor. They'd just replace them..
You should treat yourself to slotted rotors and only buy copper-ceramic pads its big value stopping power and the setup lasts forever as the rotors will never really wear if they are slotted and you don't use highly metallic pads on them.
$12k machine, charge $20 a rotor or drum to turn, thatll take YEARS before it makes a profit. And any repairs or consumables during those years, might not make a profit at all.
This machine is at a Subaru dealership where the cheapest OEM rotor is $136 and that’s on an Impreza. We cut about 10 rotors a day so it paid for itself in less than 6 months.
"and it usually cost $180 labor". How would that save money if rotors can be bought new for under $80 dollars a pair. Misinformation??? As far as I know cutting rotors cost between $15 abd $40 a pair.
Well, then you would have to take them off yourself, find a way to get them to AutoZone if you don’t have another car, then go back and pick them up. Not that easy for most people.
