Motorcycle Brake Rotor Button/Bobbin cleaning

  • This video shows how to clean the Brake Rotor Buttons aka Bobbins. Over time, Brake dust, Dirt and Corrosion can build up between the buttons on Semi-Floating disks causing the rotor to not move freely from side to side. If you have pulsing in the Brake lever and vibration through the bars when braking, don't be so quick to replace your rotors. Try this first.

    You don't need a drill or an impact wrench to perform this, I just used the power tool to speed up the procedure, can you can use a wrench or a socket wrench as well.

    Thanks, mate. Might try it this weekend. I don't feel any pulsing through the lever but I definitely feel how the braking isn't consistent at low/mid braking. It's like if the pads have more stopping power at certain positions around the rotor and less at others.

    Instead of using bolts and nuts, it's quicker to use an easy out tap. It'll grab the inside of the bobbins and spin them.

    The only people I see doing this are'Home mechanics'.I Have been riding bikes for years,Have experienced Drum brakes,Solid rotors,Floating rotors etc.No one I know has ever mentioned about cleaning the rivets/bobbins on floating rotors.EBC web site explains in depth how a floating rotor works..I see you have a KTM.Maybe riding too fast and ABS coming on.I get clicking from mine occasionally when slowing down after a spirited ride...Ride safe.

      @cfltitan 2 роки тому +1

      They’re not rivets, they’re bobbins. They are designed to be slightly loose so the rotors can move slightly side to side for smooth braking. That’s why they’re called free floated rotors.

      They can still be warped and spin freely, only way to tell is to measure the run-out (warpage) with a dial indicator. What brand is your rotor?

    Excellent work, excellent idea. I would have the rotors removed from the wheel to prevent the brake clean spray or other solvents from damaging the finish on the wheels. Brake clean is very bad for painted surfaces.

    any ideas if i cant free them with a bolt and washers. mine are seized solid

    • @PRL1290
      @PRL1290  5 років тому +1

      It should free them up, because when you tighten the bolt it squeezes the button. If they're really that stuck, try breaking it free by moving the rotor from side to side while spraying brake cleaner.

    • @butrint904
      @butrint904 5 років тому +1

      They dont need to rotate. Leave them alone. The bobbins are for thermal expansion and not to make the disc a 'floating disc'. The floating part of the brakes comes from either the caliper floating or having pistons on both sides which evens the pressure on both sides of the disc.

      @@butrint904 I would say if there is nothing wrong with your brakes (feel wise) leave them alone but for example if 2 or 3 bobbins seize up and the rest are free that may cause wobble which feels like disc warping so the only solution would be to clean them. This is just speculation though because it worked for me but I'm not sure if my actual disc was bent or the stuck bobbins shifted the disc just enough to make my brake lever wobble when braking, in any case cleaning them solved the problem for me.

      Agreed. It is unnecessary. If your rotors aren't warped and you're having chatter or a wobble feeling when you brake it is an axle alignment and/or brake pad alignment problem. This is nonsense.

    Don’t do this. You are causing friction that can damage your rotors Instead use simple green to clean your rotor bobbins on a regular basis. Much safer.

    No!!!! Look closely and there are metal shavings dropping between sprays with that liquid. The dirt colour in the liquid as it falls is carbon particles from the higher carbon metal that makes the braking discs. Utter utter madness doing what you're doing.
