Came across this video while explaining why you don't just put pads on a car without turning or replacing the rotors. This was perfectly instructed with all the right steps. Perfectly done, and reminded me of my old auto shop instructor in high school so many years ago - you are an excellent teacher. Thank you for this :)
I am SOOOOO HAPPY to see high schools still teach the trades!!!!! Not everyone needs to go to college to make a great living! A great mechanic will NEVER be unemployed!
FYI from AMMCO's website: Note: Either rough or finish cuts may be taken to resurface a rotor. Generally, finish cuts should be 0.004” to 0.006” per side. Very shallow cuts of less than 0.004” per side tend to reduce tool bit life because the heat generated during reconditioning isn’t transferred to the rotor efficiently. Rough cuts may be taken from 0.006” to 0.010” per side.
Also its not called a vibration spacer. Its called a rubber self-aligning spacer. If you have ever seen one of them apart Its a biconvex washer sandwiched between two concave washers. allowing it to move a little bit when tightening the arbor nut up against it. It helps compensate for any unevenness between the cups, spacer and arbor nut.
Never cut just 2 thousandths off. When you take that light of a cut the heat doesnt not transfer to the bits and you will wear your bits out faster. Always cut between 4 to 6 thousandths By the way I have been a certified Ammco Technician for 13 years
I need a certified Ammco Technician to run mine for me, I've had one in my shop hooked up for over 2 years and have never used it. lol Its just that new rotors are pretty cheap these days and I just slap them on. I played with the machine once but didn't know what correct things to use so said meh... now I'm here searching videos to see what is what because I hate the darn thing just sitting around so figured id play with it some more, even if I never really use it. I have never known what to charge anyone if I ever did them for them anyways... when the new ones are elcheapo. I see video's of dudes using them all the time so there must be some money in it though...hmm
there's too many things wrong with this video. I've been cutting rotors for years. I never measure them. I cut them until they are good. I can actually see if a rotor is bad
I have also worked on cars for years, for various dealerships. If you are not measuring brake rotors after you have removed material from them, you are doing it wrong. I don't get how you can consider having proof that a machined rotor is still within the specified thickness a bad thing. It's required in the dealerships I have worked in to document such information, you cannot have too much information.

very very few high schools teach auto shop anymore :(
I have this model of lathe machine for 35 years, it's a great machine, works like first day
Thanks for the video. Very thorough and detailed. Very helpful, thanks
Excellent video.
Each step so easy and clear to follow.

I think he did do 0.004 right? He did to cycles of 0.002 I think. Sorry, I am still learning
Very well done video for a beginner like me. Thank you!

Great instructional video, thanks for sharing it.
Very good video. Thank you.
MUCHAS GRACIAS POR ESTE VIDEO ES DE MUCHA AYUDA. THANK YOU VERY MUCH FOR THIS VIDEO HELP ME A LOT

James Tiberi pretty good video though

Cool man do you have a vid for the brake drums?
mine is cutting swirls in the rotors. any ideas?
did you use a vibration damper on the rotor
@@PeterShaw-lb9lt yes. I haven’t had time to mess with it but it’s called a record swirl. Looks like an old LP groove being cut into the rotor.
Do you have silencer band?
How much do i get with the machine?
did you clean inside for sure strait
What size would you recommend to use for the break lathe adjustment, is it always .02 as you make 2 passes on the surface or does it varies?
Thanks for the info, very helpfull, more power to you.
WIsh I knew where to find discard thickness for a rotor and drum as not all have them :(
It's hard to find shops now days that will turn rotors,most will tell you,no,but we replace them, well hell I can do that without you charging me!
Danny Mcclure same over here in Canada Ontario...Canadian tire hasn’t cut brake rotors in years and he said it would be about $50 a rotor

Where did you get that hone stone tool? Can you post a link?
Harbor freight nowadays
Good video, ok?
You don't need to do a "non-directional" wire wheel the rotor....
you do as the cutting tips come out on the rotor they leve a slight thread on the surface it will pink up on the pads
this is 4100 model
Helo
K?

Well you still have to measure them, at least in my school

Зачем резиновый ремень надевать на диск?
it stops a ringing vibration between the rotor and the cutting tips if it vibrates it leaves a rough surface on the rotor
What do you do when he rotor goes up and down like a roller coaster I keep trying to center it and never works
