Great explanation of rotor lateral runout.

Thanks...

I love these old school cartoon teaching tutorials.

Very unhelpful

head can cause this too..

Felt by the driver what?

What exactly are you diagnosing ? If the rotor is warped then resurface the rotor...if it's too far warped then replace it..

👍👍👍

This is so wrong on so many levels, I don't know where to begin. Hopefully your brake voodoo ceremony is no longer in business.

Old school stuff, still use it to this day!!

new rotors need to be checked, That said cheap rotors do not hold up well and for the most part, expensive rotors are not much better. It's a corporate thing, but hey people like it when they get fleeced.What's in your wallet?

un inventing the brake- to sell more junk and cause more shoptime

Do any garages actually do this in real life?

Lol I’ve been an automotive technician for 15 years this is the first I’ve heard of taper correction plates. How about you machine the brake rotor if it’s warped. Under minimum thickness? Time to replace it.

nOw that was fk'n clear! That's how you do training videos! Once again, KZbin University does it again...

Or you could chuck the rotor up in the lathe and take the high spot out !

Very nice

Braking is much more intricate than you think.

Calculating angle with dti.

sadly, the most commonly ignored by brake rotor installer.. i have learnt the hard way. last time having brake rotor replaced, i personnally wipe cleaned the mating surfaces while ignoring confused look of the installer.

Very brief explanation on Dial indicator.Much appreciated. You may be wanting to have a Wireless Dial Indicator "BlueDial" to get the measurements on your smart device with our custom App to get the readings and keep a graph for it.

Bummer if you find out the hub has the runout or the wheel bearing has play.

It seems like the hub is the problem.

This is a revolutionary perspective for DIY brake job replacements. I never heard about the importance of checking runout in any of the DIY youtube videos and I've been having issues with rotor vibrations ever since I started doing brake by myself. I've always just resorted to replacing the rotor and pads, when that happened, and assumed that the rotors were simply of poor quality. Now I know better and I am ordering a runout gauge to check my HUBs and rotors and see what's really going on. Great stuff!

Why is this cut short

end of video shows www.brakealign.com but that site is no good.

Put the runout gauge on the hub?

The fix is to take off the rotor and use a dial indicator to measure the lateral run out of the hub. If the hub has .001 or less of lateral run out, you would know the hub is good. So you would then use a wire brush to clean all rust off of the hub assembly, you could even do this before testing it for lateral run out. Then install a new rotor on after applying antiseize to the hub surface to ensure there is no rust or corrosion to the surface over time that could cause lateral run out and make sure to only torque the lug nuts to spec and never use any impact guns to install the lug nuts.

3:05 What difference does it make if you spin it counter-clockwise?

Why not at least try reinstalling the rotor at 180 degrees difference and check it again?

what is the fix, please reply. thank you.

From what i remember from going to Tech school is that there can be two things wrong here. 1- what was the runout before machining and was the rotor set up on the lathe to be the same runout as was on the vehicle? 2- what is the condition of the wheel bearings, are they part of the problem and getting wore out? Yes rotors can warp by heat due to long periods of brake application time and from improper torquing of the lug nuts but this also has to be taken in when servicing the brakes. IE. i did not see the tech on the video check runout of the hub assembly as well to see if it was rotor or hub issue. These may have some value but why is there 0.006 runout on a machined rotor? Doesn't compute with me, something was done, or is wrong with the big picture.

I wants to know calibration procedure for dial gauge

great information, thanks so much

J Lynam missed the point, even with true rotors (.002 max. runout), in many cases the face of the associated hub may not be true (virtually no runout), hence, causing lateral runout which will be magnified to a calculable degree at the rotor face. It's kinda like love and marriage. You can't have one without the other.

Thanks great information!

Seems like a waste of time. Why not just replace the rotor?

That's pretty sweet! A shade-tree can use those an get the benefits of a full Pro-Cut on-car lathe.

Great Job! This is the first time someone talked about thickness variation causing pulsation something I have been preaching a long time. I have been a tech for 45 years. Thanks, Bill

machine it if its thick enough but you have to measure it with a micrometer and pull up alldata for rotor measurement specifications

This is the only video on all of the internet that I could find from someone who actually knows how to replace brake discs properly.

Excellent!

Great information!

Excellent instructions, thanks!
