    Well got my bike back from being serviced from local bike and was told front disc piston was not going back and was slightly rubbing and the only way was to send them to formula for them to vacuum bleed them like you I have never heard of this before year of bike is 2012
  • But that's not necessarily the year of the brake.

    A vacuum (actually just reducing pressure to encourage air bubbles out) is referred to in Step Eight of this sequence.

    But surely just getting the bike back from being serviced the shop should bleed the brakes if they needed doing? And why say that the piston would not retract and would have to sent back to formula?

    No, it's not part of routine servicing so 1/ they wouldn't do it as part of what was quoted so 2/ as it would cost extra they must ask you first.

    A little rubbing is normal (or at least not abnormal) is the rub actually slowing the wheel?

    Calliper may need centring, or it could be a bit of grub on the piston, neither are hard, doubt it will be air, after all how did it get in?

  • Formulas have horrendously tight pad to disk clearance. Better in recent years but shit in 2013 and past years.

    True as I can't remember it rubbing before this service I will try to get out on it tomorrow as see how it goes
