Really love the detailed logic and reasoning behind your actions, when I know why something is done it helps me understand what the final result should be.
OTC 8342 hub resurfacing Roloc sanding discs (usually use 80-100 grit brown). 3M ones work and seem to hold together well. I buy mostly 2", but always have 3" for certain hubs and calipers The purple strip and clean are good too. To save on shop supplies use a steel bristle brush (straight and cone) and a fine burr bit (Careful not to take any core material off!) with either a drill or die grinder to work most of the rust off, saving the rolocs for final finish.
This is a great video. I think only half of the mechanics out there even bother cleaning the hub face and less than 25 percent check for run out and do a finishing on-car lathe to get it within spec.
Great video y'all. Such an important part of a quality brake job. Could you also take a torch and run an oxidizing flame to help get that heavy scale to just pop off or at least loosen up? Being careful of course not to cook the bearing or fatigue the spindle itself mind you. Perhaps that's too risky but I thought it might be another option. Thanks as always for your time making these videos!
Wow, who says you don't learn something new every day. That was a great illustration of how not doing something as "simple" as cleaning your hubs can cause you to fail runout by X7.
When dealing with scale like that as we have in new york warm it up with a torch just to the point where the rust will pop off on its own . don't heat it to much but at the right temp it will pop then go in with your disks
Thanks for the video. I had never thought to clean the hub to improve braking performance. I have the rims off for power coating. Guess I will be using the needle scaler and a thin coat of high heat paint.
Interesting you said it was one of the worst you have seen. I see lots of Jeep models with what looks like lots of premature rust. I long since decided Jeeps (Chryslers?) are rust buckets.
An air angle grinder is much better spins at much higher RPM than those drills. That's what I use and I live in New York we get plenty of rust and road salt
I removed the cv joint and there was a lot of rust inside the hub, all around the perimeter. Anyone know what kind of tool to get the rust off inside that circle?
Good video but very biased on the sanding tool you barely used the first tool and then gave a tiny cut away then started with the second tool and did a longer cut away as you worked that one for longer to get that scaled rust
Really love the detailed logic and reasoning behind your actions, when I know why something is done it helps me understand what the final result should be.
Great video. It would be nice to have links to the tools demonstrated.

Great video! Mueller-Kueps 460 202 Thin Brake Caliper File works great too! Has a "chisel" end too for getting under the scaled rust.
Great job, and quality service to your customer. That's how business always should be done.
Thanks for the video, was considering using a needle scaler but wasn't sure if that was safe on the hub.
Thank you, brilliant. Weill explained, great presentation and information.

What is run out?
@@Casket_Music😂😂😂😂😂😂😂😂
@@Casket_Music When you spin the disc, it's basically how much it wobbles rather than spinning perfectly straight
Super great video, great work on the hub there. Great info. Have a mighty fine day.

Take an old file and grind the end flat ...makes an awesome scraper
Agree with everything he said.
I'm lazy, I would look to change to a new hub and use a nice thin layer of synthetic paste to prevent the issue.
Can u use silicone-teflon paste?
Thanks for the video. I had never thought to clean the hub to improve braking performance. I have the rims off for power coating. Guess I will be using the needle scaler and a thin coat of high heat paint.
Excellent. What he said makes a lot of sense.
...thanks Ray, you're the bestos...
Sounds like it could just use a new hub altogether
Right... hahashahahahah
No
Interesting you said it was one of the worst you have seen. I see lots of Jeep models with what looks like lots of premature rust. I long since decided Jeeps (Chryslers?) are rust buckets.
could you put some sort of grease or anti-sieze on the hub to prevent this from happening again?
3M copper anti seize brake lube
Antiseize or a small amount of marine grease.
Fluid Film
Is it worth painting these hubs with heavy duty heat resistant paint for added protection or is that not an option?
just use a slight coat of Fluid Film and you'll be good to go
An air angle grinder is much better spins at much higher RPM than those drills. That's what I use and I live in New York we get plenty of rust and road salt
Total noob here, but what type of tool uses roloc disc's? Also what grit number should you use? Thanks!
3m hub cleaning kit
I removed the cv joint and there was a lot of rust inside the hub, all around the perimeter. Anyone know what kind of tool to get the rust off inside that circle?
What book do I use for runout specs, please, if you do not mind ? I donot see specs for a lot of vehicles on Mitchel1.
What color of roloc should I use?
Why not refinish the hub with a high temp caliper paint at that final stage to since its so cleaned up? Is that not something recommended?
With the tight seal needed between metal, having a painted surfaces might compromise that. Plus when it scratches that's going to cause other problems
I would have those studs removed by a Pneumatic Hammer. Grind the entire Hub with a Hub Grinder. That's how I would do it.
I never heard any mention of replacing the hub....

Great video!!
Great video
What kind of roloc discs would one use for this?
3m has a hub cleaning kit, you just have to buy the disks seperately, it's the most popular, you can use a drill or an angle grinder
I haven't seen hubs that clean on any of my cars I've owned :D Road salt and proper winters aren't cool.
What happens if all your wheel hubs are like this?
You clean them all! 🤷🏻♂️
How does it even happen
Oddly satisfying.
And all the makers had to do was galvanize the thing and none of this would be necessary.
Good video but very biased on the sanding tool you barely used the first tool and then gave a tiny cut away then started with the second tool and did a longer cut away as you worked that one for longer to get that scaled rust
Clean the hub and spray OSPHO on it. Personally I would have replaced the hub.
Plot twist, the hub bearing was toast and had to be replaced anyway.
needle scaler still peens the surface of the hub flange, i use a carbide scraper, its tedious, but works well.
Protect that hearing. 4:07
two thousandths runout is excessive in my opinion.
Rip to whoever has to do that Wheel Bearing.....
The other option is to refrain from buying a JEEP!
Some guys have never ever did a proper brake job.
Couldn't you just soak it in some gas or some shit?
Penatrol?
