At this point I feel like I got half a bike mechanics education from this channel. Honestly it's even working for them. Whenever I buy new bike tools I always look for park tool stuff because 1. I know the tools are high quality. 2. I'm thankful for all the free high quality information they provide on KZfaq.

I can't possible explain how grateful I am for Park Tools producing these videos!

You can tell a lot of work was put into this video. Keep it up guys, we really appreciate it!

Well done. I really appreciate the videographer and graphics team

wow, ALL youtube instructional videos should take note, THIS is how it's done, excellent work and thank you for such a great tutorial

Just adding my props. This channel rocks, and thanks to you guys, a guy who despises disc brakes (me) has been able to coexist with them with no more than the government-mandated amount of swearing.

4:56 This is the best instruction i've ever seen! Nice graphics team

And this is why I buy Park Tool. Many thanks for explaining things succinctly.

Thanks. Now it’s clear to me how to ID a worn rotor that needs to be replaced. Good stuff…!

The only instructional video series I regularly binge-watch.

Mine is 160 180 my mountain bike is brand new hydraulic just be careful they have make different design of rotors awesome video it makes my day even better

I buy tools from you just to thank you for these videos.

It is also very important to establish a good rapport between the bike mechanic, the tools and even the bike itself as can be observed by the bike mechanic quietly establishing his displeasure of the lack of cooperation from the other two at 9:05

Super thorough!! You guys even covered adapters, which is what I was looking for, covered the adapter type I bought, plus the bonus tip at the end about caliper alignment.

thanks park tools, i did wonder if possible to change from single centre locking to the 5 bolt locking system...and now i know without having to over spend, again...... thank you very much PT

This is really good, and so detailed it made me realize I should just bring my bike to the shop for this work!

My rotor got mineral oil on it. And I stripped the bolts. So I'm on the verge of a mental breakdown over here. 🙃

Incredibly well put together video. I have the center lock version disc which needs the external tool. And just to let you guys know, that thing absolutely sucks. I have a tool (not Park Tool, but a cheap chinese one), and it's impossible to remove, as soon as I try turning, the goddamn tool just pops off. I have to take the whole bike to the bike shop. The old school 6 bolt system is just sooo much better, I don't know why the hell did Shimano feel like he needed to reinvent the wheel, and make the whole thing worse, needing extra tools and such.

probably the best bike work vids on the net!

Nice clear and concise video. Kudos for wearing gloves too. I see far too many KZfaq videos where the presenters aren't wearing gloves while handling new components.

Thanks for the tip on using the Loc-tite.

Just shows you can trust Park Tool to keep their videos completely up to date by mentioning lockring rotors come in 2 types of lockrings that require different tools!

These videos are underrated.

3.36 makes loosening the bolts look so easy. I've tried everything to get mine out to no avail and pretty much rounded out the bolts.

Excellent video as always, very informative. Thanks.

Your videos are the best… thanks a lot

Best video tutorial ... as usual by Park Tool staff. Thanks!

Great video. Just wanted to point out that at 6:40 you say to use isopropyl alcohol but the video shows denatured alcohol. They aren't the same thing.

Am I the only person disappointed that the paper towels and alcohol are not also blue?

Truman should get his own show, we can call it, wait for it, "The Truman Show."

Great job parktools !! 👍👍

9:21 This guy sounds fed up with having to explain this basic shee to us. It's just very convoluted with new unnecessary proprietary technologies being developed all the time to require you to upgrade all related parts in order to fit the standard so I'm glad this video exists

Great video man! Be blessed 🙌

Truman, can I have your autograph? Seriously, great job on this instructional video. It's been been fun following your bicycle related career path, from teenage bike builder to Park Tool video star!

Honestly, I am an average user and happened to get myself a bike with center lock. It should be illegal to sell such things to "none-pros". Like...what the heck

Thanks for the video. Helped a ton!

Is it normal for centerlock Shimano disc brakes to move a lidle bit under load?

Hey park tool i bought a new disc rotor and it came bent the person then told me this : “All rotors need truing during installation as they are a stamped steel. I recommend purchasing a rotor truing tool in order to install these correctly and true them for use.” Can you tell me if this is true ?

Excellent video, veeery complete

Do you have a video on how to replace hydraulic brake lines?

Should the threads of the lock ring, for centerlock, be greased or not greased. I note that the instructions indicate to not grease the splines.

Great video! Thanks a lot

Just upgraded from F/R 160 to F/R 203. Completely pointless - I ride the thing in town - but a lot of fun😁😁

Thanks 🙏

Very interesting and informative presentation.

Im feeling like studying at school, gosh why the bicycle got so sofisticated

are the internal and external lock ring types interchangeable?

Very helpful video thanks 👍😁

woooww!! really loved this video, very instructional

Park Tool HPG-1 has a max operating temperature of 540° F. DOT 5.1 has a boiling point of 518° F, and Shimano and TRP mineral oil have similar boiling points. So shouldn't it be ok to use grease on rotor bolts?

I need this tool to unlock the locking ring on a Shimano disc brake rotor. But it keeps slipping off. I can't use the BBT69.2 because the axle protrudes through the hold where the ratchet handle would engage. What do do?

I ALWAYS use COPPER LUBE/ ANTI Sieze on ROTOR BOLTS !!!!!!!!!!!!!

What's the reason for upgrading from 160 to 180? I'm new to the biking thing so I was just curious

6:04 for centerlock rotors

7:41 can you see theres a internal spline does that tool still exists now adays

is it possible to install an internal locking rotor on a wheel that previously had an external lockring?

Great video !

u really do a good job 😁

thanks

epic video, thanks

Great vid!

My centerlock rotor is really stuck. My local shop couldn’t even get it off. Time for a new hub? Maybe some tips?

How long can electric bike rotors last before charging them, and what sizes are required for both front and rear wheels ?

my disc is a 10 year old avid G3CS and its still going strong and my rear beake pads are work so thin their barely a fingernail thickness away from the backing plate

When I what to a bike shop you know buy something for my bike also I saw this disc break has two arrows I was shocked 😮 it should be one way rotor disc and love ❤️ this video so much make sure disc is perfect tight 7 🔒 I never seen it before it my first time see it my is 6 bolts

Veri nais videou (Very nice video)

5:47 Perhaps wipe the rotor with isoprophyl alcohol prior you install the rotor which make the wiping much easier

Just unscrewed my factory/store tightened center lock rotor by hand after 4.5 years of use... I was less than happy with this.

nice video,

My brakes are squeking and i sanded down the pads a bit to get dirt and such off and used that alcohol with a rag onto the disc and they still squeking so what should i do? Change out pads and disc or what

where is calvin jones

thank u!

What a great video as expected , a lot of comprehensive info . I have a question I hope you can answer . Can a standard 6 bolt rotor that is cut from one piece of material be interchanged with a 6 bolt rotor that has the aluminum spider in the center , our will there be rubbing or misalignment of some sort ??

thank u love the content

how do you pull of the 6 bold adapter ?

Hi, i have the same center lock rotor as used in the video. When trying to do a skid with the back wheel the entire wheel starts to vibrate and it doesn't skid nice, can this be because the lockring isn't tight enough?

What tools can I use besides the exact correct bit for 6 bolt disc, I got 1 off but the rest are way too tight and now somewhat stripped

Is the point of Shimano to make every single part require a unique tool?

Should I replace it if I sprayed it w/ wd40 or use degreaser?

Hi, on my bike are rotors with center lock and lock rings are with external nothces. So, are all center lock discs compatibile with external lock rings? I use shimano sm-rt10 CL discs and can I replace it with sm-rt30 CL discs and keep external notches lock rings? Thank you.

Bloody hell,.....bring back rim brakes! 😲😲😲

I think I stripped my bolts out they were on there really tight. Do you have any ideas of how I can remove them?

I want to remove the front brake off my dirt jump bike, is it as simple as just removing it or do I need to get spacers.

I was trying to change my discs today but the 6 screws are so tide, that I broke my key for T24. I sprayed with WD40 but still the same, the screws don't want to move 😥

What does the G Y17 stamp mean on a Hayes 160 brake rotor?

Hi, Is it possible to install double rotor on the front? These days, there's a portable caliper which able to fix on the side of the frame or fork. Is this doable?

Hi there.... My bike's rotor got free play back n forth.. Is it because the aluminum shim between rotor & centerlock missing/worn out?

Am fine I have 4 rotor disc and it very scary same mount my is 160 avid BB both be careful too much it can break like I have broken bults

What else can u use to wipe both sides if u dont have the alcohol

Can you use the either a 6 volt or centerlock disk brake rotor with the same disk brakes? thinking of upgrading my wheels but the sets I want come only in center lock so was just thinking of changing the rotor insted of upgrading the whole groupset. Can this be done? Thankyou!

New bike is also a great option )

Hi, is it safe to put 180mm on front of my ciclocross bike? It's an aluminum fork by the way.

Can centerlock rotors be exchanged,one with outher notch nut to be replaced with inner spline?

Should I replace my pads when replacing the rotors? Even if the pads are still good?

Hello There , Great video. I have a newbie question :) Recently i bought a caliper that instead of B01s pad it had a G03S Resin pad ( BR317 caliper ) and i saw that it wasn't touching all the surface as the B01s pad did, it is narrower ! So the question is : is it safe to use as long as the rotor is the same diameter ,example 160mm . or do i have to change the rotor to the appropriate one ,example from RT-30 which i have now to RT-54 which Shimano states at the site as compatible ? Can i use even a better quality rotor like the SM-RT68 so i can use metal pads in the future ? Thank you

Can u help me pls?...When i push breakes the break disk stops but the wheel is rrolling... What can i do?

7:55 What do i do when the quick release handle is still there and i can´t reach the center lock? I´m an noob in working on bikes and I hope someone sees this and give me an advice. I can´t find a tutorial where they show how to remove the quick release handle.

What if i have six bolts but it's like bolts but the heads of the bolts are bold

What sort of person leaves a dislike on one of these videos?

Would anything bad happen if I took off the front Centerlock rotor completely?
