Brake Disc Bobbins

Kind of funny this problem of never cleaner your brakes rotors-I do that just before I go for a ride and it keeps the pads nice and clean too-the problems that come up when you ride a 1,000 miles and never look down to see if bolts and brakes are working ,its all ways better to wait till they fail when you need them according to BB!

 

^ Really? Thanks for the tip, sagacious one! My point was that as much as I've cleaned rotors, etc I never thought to break the bobbins free.

 

Damn...I wish I knew about this before I went and bought new rotors, may have saved me some deniero. Oh well, good thing I like my new rotors. Anywho, great find Randay!

 

I doubt material would build up with the rotors are cleaned once in a while, but perhaps when they get really old the cleaner doesn't work any more

 

I will take a look at my bobbins but from just looking at them they look fine but I guess its not how they look , its if they spin, my brakes seem a bit like rubber to me. I assume the brake lines are expanding. But something is wrong, the brakes should be grabbing better. I am going to try and not be a negative poster anymore. It just isn't what I like be. Randy has more miles then almost anyone on a 800-he does know more than I do at crunching miles. I am more of a short distance sport rider-at least right now.

 

Interesting video. I will check my 07. Will be good to see if age is a factor as well. I only have 2600ish on the clock.

 

Randy, that was terrific. I have never even heard of "bobbins", but the video (and his others) are great. Thanks for the info.

You are most welcome.

@ SOW. A big part of this thread is that there is the potential for a fixable problem that most of us are not aware of. This particular problem cannot be fixed by just washing or sprayimg brake cleaner on it. It can't be detected by simply looking at things. It is a hands on maintainance check. Something which appears most of us were unaware of.

 

I have thought about this some more. I think the way to keep these bobbins free moving is to clean them from time to time with brake cleaner. I think everyone got that. Initially, I was thinking of lubing mine up with graphite. I also use a very good bicycle chain lube on many things. Tri Flo. Expensive as hell but a great lube.

But back to our bobbins. I think they were designed to operate clean and dry. Would adding lube to them not attract and cause dirt, and brake dust for that matter, to collect and cake up in these joints, and therefore add to the problem?

 

Yeah, you may be right about that. I've got some brake cleaner and I think I'll go give them a couple blasts. The more I think about it the more I think you're right. Thanks for the nudge.

 

I'm gonna do this soon although I definitely need new pads and fluid aswell. That's gonna be fun to change great find Randy

 

I have been hitting the rotors all the time with brake cleaner-it appears you need the hit the whole rotor-not just the braking surface.

 

If you're just changing the fluid it isn't that bad. Empty the master cylinder but make sure you don't pull the lever, refill with fresh fluid, pump the new fluid through the system. Since you've introduced no air into the system, you really don't have any bleeding to do, just moving the new fluid through to replace the old. The worst part is just making sure you get all the bleed points.

Ah, I see you have the ABS model, so I hope it isn't any different. As long as you keep the air out you should be good.

 

Randy I been hitting the bobbins with tons of brake cleaner-I think if the bobbins aren't that caked up with crap that's all you need to do- because my brakes actually got better I will keep hitting those bobbins with cleaner- I was not doing this before.

Pads too, what's the best way to completely drain the brake fluid, so that im not keeping any old stuff at all, also anyone know the capacity of the whole braking system?

 

Did you view the video I attached? Did you follow that guys instructions and turn these bobbins. Did you use a bolt and nut so that you can turn the bobbin while spinning it. Spray all you want, if it is caked up between the outside edge of the bobbin and the inside edge of the hole in the rotor,you need to move something around so that the brake solvent can get in there the clean things up. I just don't understand you Sonofwolf. You seem take bits an pieces of peoples advice and do your own thing and your practices are questioned more than regularly here. They are questioned pretty much each and every time you post.

I don't know how old you are, if you work or what you do for work, but judging by the way you behave here, I can't see you holding gainful employment for any amount of time if you don't follow instructions.

Do your thing. I really don't care. I will continue to follow the advise of most people I come across, because undoubtedly, most peoples knowledge about bike maintenance, is far better than mine. That is how I have learned the little that I do know.

Bonn voyage!
