Front discs and disc bolts

[Fazerider]

Have the discs been changed before? If not, the original threadlock may well have bonded the bolts in too firmly for them to be loosened unless you warm the hub up first.
Provided you get them out without mishap there's no risk in re-using the bolts, my bike is on its fourth set of front discs and the original bolts are still doing the job ok.
