1260 Front Brake Noise When Pushing Around ?

Discussion in 'Multistrada' started by Speedie, Dec 19, 2023.

  1. I wonder If I could ask a question and possible actions to cure it ? Light binding noise when pushing the bike out of the garage. I have tried cleaning the disc bobbins with no luck and wondered if it maybe something to do with caliper centralisation . The brakes do not judder when riding so don't suspect warped discs ?

    Thanks

  2. You can loosed the calipers, apply the front brake and re-tighten whilst the brake is still held, that'll centralise the calipers.
    Also, the forks may not be aligned, the right leg is floating on the wheel spindle, you're supposed to tighten up the left leg and leave the pinch bolts lose on the right leg, then hold the front brake and push the suspension down hard, this will allow the leg to find the right position on the spindle, if you have skyhook you'll need the ignition on.
     
  3. Also indicative of the caliper pistons not releasing. When was the last time you cleaned the calipers and pistons ? Andy

  4. In the past if I've had that and cured it by cleaning the discs. Certainly the disc bobbins should be free to turn, so check that.
    To clean the discs use Brake Cleaner and rub the discs both sides as best you can with a brass brush and/or wire wool. If using wire wool make every effort to remove any wire wool residue afterwards.
    Be aware that Brake Cleaner will damage paintwork, so first cover up any that's vulnerable with rags etc.
    If the disc bobbins are free to turn that will ensure automatic disc centralisation as they are floating discs.
     
  5. Quite normal tbh. More pronounced when going backwards. All the above would deal with potential issues, but if it's slight and there are no braking issues, IMO, it's down to how the pads are presented to the discs and why it's more noticeable when going backwards due to the drillings in the disc catching the trailing edge of the pads.

  6. Yep, mine did that

  7. I haven't specifically but it has had two new calipers due to theft whilst on the dealer forecourt for sale. So based on other comments I'm thinking check the bobbins again and failing that loosen the front spindle pinch bolts and if that doesn't cure it then I'll live with it.
     
  8. Technique I developed for releasing the bobbins was to use a cap head bolt through the bobbin, nut on the back, tiny blob of release fluid and rotate with an electric screwdriver. Clean off with chain cleaner. Andy

  9. Spinning the bobbins has been a trick for years and is ok for a quick clean. Don’t get carried away though, especially if using a drill to spin them. The rotor and bobbins are steel but the carrier aluminium. I’ve seen a couple that have been “freed” off with a bit too much enthusiasm and worn the carrier, effectively making the mounting for the bobbin oval. This ends up allowing the rotor to move radially and the disc is basically junk. It’s also possible to crack the shim or spring on the back of the bobbin.

  10. Had three multis. All did it.

  11. My V4S does it.
     
  12. Mine have always done it. I’ve stopped it in the past by cleaning everything and a smear of copper slip on the back of the pads but after a while it inevitably starts again.
     
  13. WD40 liberally applied, good for anti corrosion also.

    Or as reading between the lines above would suggest , just ride and enjoy.

  14. Liberally applied where? I’m always very careful spraying that stuff anywhere near the discs.

  15. They all do it and not just Multis. My Speed Triple did it as well. Its not an issue.

  16. Whoosh?
     
  17. WD40 near the discs? Not sure I'd advise that to clean them. Proper brake cleaner will do the trick. For the bobbins, I normally lightly tap with a rubber mallet and turn by hand whilst cleaning with brake cleaner.

    As for the rubbing, I've had 3 multi's, only the 2 1260's had the issue. My current one still rubs, but it's very faint and as others have said, it's a none issue.

    Indeed try the suggestions posted by @GTmorgan. If they are really binding and only in certain spots, then it could be a warped disc which I had on my current multi, horrible feeling when under braking. To solve this, I simply upgraded the discs to series Oro with red pads at the same time. They are brilliant and very stable feeling under all brake pressure ranges.

    Thanks for the reminder though, I've not cleaned my calipers and discs in months, a job for this evening!
     
  18. Me too, especially where centrifugal forces are at play to displace it!
     
  19. My 1260 does this. learnt to ignore it.

  20. My 1260S did this as well. I removed the callipers and greased the back of the pads with copperslip. Getting the callipers off without scratching the wheel is difficult. Tape the wheel up prior to attempting it. There is a gnats cock between the wheel and calliper when trying to remove.
