Thank you for the video. I try to make educational videos as well to give back. I want to, also, say that you and all the UA-cam creators who make educational videos are my heroes. Thank you again!
Thank you for your kind words. I do enjoy making these videos.
Great video thank you for the info I needed
I am glad that it was a help
Just got home from Gettysburg. It was nice meeting you, and you have a new subscriber.
Thank ypu. It was great meeting you as well. I am here till tomorrow. Ride often and ride hard.
Great meeting you in Gettysburg. 👍🏼
I agree. Awesome meeting you as well.
Thanks for sharing great video
Thank you so much for watching.
Very informative thanks
No problem. I hope that this helps you out.
As a non Harley guy can you tell me how the rotor is floating if its bolted to the wheel. Surely the idea of a floating rotor is for lateral self alignment with the caliper and pads. Also why do HD use a mix of metric and imperial fastners?
Yes I can. The boots hold the spacers tight and the spring washers allow the rotor to float.
On super sport bikes, rotors can be full floating or semi-floating. The former actually jingle The whole idea is to have equal and symmetrical braking action between brake pad and rotor (self adjusting).
@@louismartin4446 yes I'm used to rattling brake discs that why I couldn't see how these were floating. Most floating discs I've seen are have a carrier that bolts to the wheel with the disc attached with bobbins.
HI Colin Full disclosure: I know nothing about HD’s as I only own sport bikes. HOw HF calls these “floating rotors” is a stretch at best.
Firstly, as you know, there is a big difference betweeen semi and FULL floating and all related to the bobbins/carrier design.
I suspect HD is calling these “floating” because those washers “act” like a semi-fixed attachment? In this vid one of those washers broke and I suspect that’s what they are supposed to do when the “semi-floating” action develops fatigue and gives away. I use the words
“Supposed to do” satirically of course. I clean my semi floating bobbins to ensure the “semi floating action” is retained. But HD has a different perspective I gather. Perhaps a brake/HD expert can chime in because I am interested in knowing the true “science” here.
I think the video and this discussion furthers our collective knowledge about bikes and - in the end- we all benefit because we love our bikes-all shapes/sizes and brands.
The shouldered washers bottom out against the wheel then the spring washers allow the rotor to move side to side so the pressure against the rotor from the pads is equal
I have a 2 week old 2022 Fat Boy and I'm having the clunking noise from my front disc brakes.
I would suggest that you bring it to the dealership.
What about aftermarket rotors? Do they all use the same spring washers? I bought an 07 electra glide ultra classic and rotors are clunking. At first I thought it was play in the axle shaft and wheel bearings but it does appear to be rotors. Im also getting pulsation when braking.
Yes the after market rotors use the same mounting hardware. I recommend replacing all the hardware when replacing the rotors. Harley states that the rotor bolts are a 1 time use only.
Does it typically cause a pulsation? I didnt hear you mention it.
@chadquinn1087 no. Pulsations are due to the warping of the rotors. Most of the time.
Could you replace these without taking the wheel off?
Yes you can. You can just do one bolt at a time and spin the wheel to get access to each bolt.
@@DrHarley thanks for the response I hit follow and I look forward to more videos
Thank you. I am in Daytona for bike week. The 12th at 8pm is a build up of my 131 and on the 18th I will be doing the motor swap live starting at 10am.
Any chance this can be done without wheel removal?
Yes. You would need to do one at a time as you rotate the wheel.
@@DrHarley I replaced all hardware rotor still moves as before. I guess my rotor is out of specs on the screw mount g points. Do you see any other option?
@@RidersUnited no I can't. Did you replace the hats and springs??
@@DrHarley yes all 3 elements of 5 mounting points.
@RidersUnited it's probably the rotor that's warn.
How many miles on that bike? I have the same issue with only 8k miles on it!
I honestly cannot remember. Was not my bike. If I gave you a number that would be a guess.
@@DrHarley
No problem. Mine only has 8k miles on it and I have the same problem. I was wondering if the one you worked on had lots of miles on it, or if not, it’s an issue they need to look into. Thanks for video and the response.
30 seconds of intro?? ugh
I have made it shorter. I agree it was too long.
@@DrHarley good man… content is great but -as you have accepted- people want to get at it. Good for you!!
Thank you for your insight. As I say. It's our channel. And everyone has input.
There’s an old saying…”Speak less, say more”. I find a lot of UA-camrs don’t get that
