How to fix a bent disc rotor

[@ScoutJoe]

wow this is budget saver tutorial! Thanks Bikeradar

[@Guoenyi]

ur workshop is so clean and organized

[@joshuajensen685]

Thank you so much! Well explained and just what I needed. I could buy a new one...but fixing things is so much more satisfying! I found this process very much like truing a wheel via spoke tightening. Takes a little while, and you end up having to fix 3 spots when you thought it was one spot. But a little patience and small corrections goes a long way.

[@johnhockings6138]

This really helped, you've definitely turned my day around. Thank you

[@othmanalkhayat9724]

Thank you thank you, that what I did, I keep observing then I start to bend, and thank you for making it so clear that it won’t get back like new, thank you!!!

[@connordodge9131]

Thank you so much! I definitely have this probably. Could this be the reason it squeaks as well?

[@ziparis]

Haha - mine did. The annoying noise prompted me to look this up!

[@bikeradar]

Thanks. We do cover buckled wheels in one of our other videos. youtube dot com /be/h2pwfdamZMQ

[@lastsonofkrypton36]

This worked perfectly. Less than 5 minutes with an adjustable wrench. Thanks!

[@IgorDz]

You just saved me $50! Thanks!

[@DanOfAllTrades]

Thanks for sharing. Have a warped disc out of the box.

[@joshuawilcox1322]

This happened to me and the caliper almost stopped working entirely... I can easily squeeze the handle to the bars.. is this a easy fix??

[@willsherman3527]

great simple explanation, exactly my problem

[@Dana5775]

I have done this but I have also used vice clamps on steel frames with heat and cold. Bend it the best you can then heat to red hot and clamp to straight steal table cooling by spraying cold water to quench wait for it to cool. It will not be like a new one but you will be able to tighten your disc caliper closer to the rotor with less chatter and still stop well.

[@Crayma800]

Dana Putnam I'm no blacksmith or engineer, but my understanding is that heating until red hot can cause stress to the metal and weaken it - causing potentially serious injury!!

[@mattecrystal6403]

is it bad if it's bent very slightly and makes a squeak when turning? should i be worried or is it just a small thing that doesn't matter to much?

[@hotrockin197]

Mine was the same and pissed me off no end. A pain in the arse

[@Azajndo]

Thanks! Today I was successfully straighten my rotor. No more rubs :D

[@GRPLiningServices]

Just the video I was after. Slight rub on mine just needs bending out rather than replace. Thanks for the video.

[@BreceLuu]

Thanks. I was able to fix it in a few minutes. It works flawlessly again.

[@thomasdrawert9568]

Probably a dumb thing to say but could you use multiple g clamps and tighten them slowly against a wooden block or flat surface to straighten them again. (Obviously after removing the brake disc from the hub)

[@AK-oz4ew]

Bent rotor will act like a spring. Clamping will not fix it, you need to bend it back past zero degree to bend it back

[@RYTHMICRIOT]

Just bought a new BMC Roadmachine. Front disc rubbing in one spot. Figured it would go away after a few rides. It's not. Watched a video on loosening the caliper, squeezing the lever, and retightening the caliper. Didn't work. This is when I noticed the heavily warped rotor. Just ordered a new one. Should've watched this video first. Didn't think it was possible to bend a rotor back into place.

[@ziparis]

Thank you - yes, not "perfect" but the annoying "zip--zip--zip" noise coming from the rear rotor every time the bend passed through the brakes is now gone :)

[@leonedias3067]

i got my brand new bike and it had a bent disc rotor. I had tried many things and probaly mad it worse. after watching this i fixed it in like 5 minutes

[@jasonb543]

What's the name of the tool and where can I get one?

[@TmanTV3]

Worked like a charm thanks for the great tutorial!

[@albertdorio7189]

Where can I get that tool?

[@TheOzzyNut]

Good basic well said tip, Looks like that wheel needs a jump on it also to take that buckle out, is that your next upload ??

[@stephenbach3042]

Thanks for this video. Very helpful. Stephen Charlottesville VA USA

[@ttv_dre0862]

Could you please tell me where I can get the first tool?

[@hotrockin197]

You need a stand to do it properly instead of struggling holding the frame & spinning the wheel😂😂😂😂😂😂

[@gellefernan4379]

What is the brand of the tools

[@Tom-wr6mq]

I can't find where its bent😭 I know it's a bent disc brake coz I've had the exact problem before but the bend is invisible

[@Maykay1312]

Im trying to buy one dh bike but the guy selling it said the back rotor is bent but there is no bend in the rotor but its still rubing like the break is constantly pressing on the rotor so im thinking mby he pressed the breaks while he took off the back wheel and it presed the piston in too far and when he put the wheel back in it started rubbing because the breaks work normaly everything feals good still breaks just like the break is slightly presed in but he gurantees the rotor is bent but thats good for me because i can lower the price down and fix it for free xd if thats the case

[@rewind9536]

Well, what if the caliper is not in place??

[@blagoyzaharinov6159]

Could someone tell me what's the song at the background?

[@HackHunter1835]

rump shaker by Tone Loke

[@danielsvancara]

OK I unbent it but now my front brake is so bad when I click it. it does not let me do a stoppie like it used too. when I click the front brake hard or just click it. the thing behind the brake pads are these green things the brake pads and I think before they were both working but now when I click it only one had moved into the rotor the other green brake pad does nothing plz help.

[@danielsvancara]

i just swapped my back brakes with my front and i tighted a allin key screw on my brake caliper to make the brakes pads closer to make it harder to press the brake to have more power/harder to pull to stop faster.

[@kentlewan]

Thank you!! Big help.

[@SoulArtSound]

I did it with hands. I was lucky, it was just slightly bent. Car pushed me out of road, that's only part damaged in crush, besides bruises and very little scratched paint. I solve that issue without police on spot, fix bike + $$ from driver.

[@HellGatefr2]

My new Magura Storm HC discs are bent...

[@bobgeorge8360]

Can you just clamp it in a vice to make it straight?

[@Toms_Short_Movies]

I'm afraid not, it needs to be bent back beyond flat to correct the fault

[@ashtonleow6382]

This worked! Thks!!

[@yusukeyusuke1999]

Thnks die telling me that helps me a lot

[@FreePalestine-FreeGaza]

Literally took me about 5 minutes to do. Ebike is safer now👌🏼💯

[@meteturhan3505]

My rotor was bad, now it's worse

[@Kushagra]

I fucked up my rotor more than normal bent using this method 😂 sometimes it works and sometimes it don't

[@hotrockin197]

Rotor hasn't touched anything but has warped🤢Cant get it to stop rubbing/ticking..so i bent it 90 degrees in rage!😅Its still rubbing lol Time for a new one. Just aint worth the hassle bikes sometimes..👊😂

[@TomTom-xh6cn]

i have a brand new merida one twenty 7500 and both breaks rubbing! since 1st time i ride the bike its like that! Bent rota on both?shame!

[@TheDatpussy]

Really!? Is it like the guys one on the video?

[@VvvnimaL]

+Tamas Szabo new breaks need time to wear in

[@rolphjucksson1840]

+T00N Like how much time

[@maclarinambor4221]

Thanks!!

[@thatweirdkid438]

I’m pretty sure I made it worse but it probably works I’m just not very good

[@gamefreakforpokemon]

this morning I was on my bike and the front wheel came off. "fuck! now I need new disks" as I was bleeding buckets from my head and arms

[@gamefreakforpokemon]

oh I'm fine. I just scraped my head (also my arms), I didn't bang it. it just looked bad because I had a couple lines of blood pouring down my face

[@MrPijus123]

How did the wheel fall off? Poor quick release tightening?

[@gamefreakforpokemon]

yeah pretty much

[@HackHunter1835]

Frank, you are joking right?

[@d_man28]

Demn. Makes me feel a lot better on my thru axle.

[@Staticzero9]

good man, thank you very much.

[@ThespankedoneRidesReviews]

Now do it again, but "do the voice" Mr ragles!

[@ACESandElGHTS]

Ñøïçê. Thanks.

[@victorkwan8850]

Salute!

[@archravenineteenseventeen]

[@darshan2good]

thanks mate

[@tommybroadway1722]

We'll you cold putti on a flat table

[@Pascaldacashcow]

I agree with this guy^. I'd me cold putti on any flat surface.

[@bumfist88]

And mashit wida rubber mallet? Will that work? +bikeradar
