Replacing footpegs

[MikeBike]

Hello guys.I have a FZS600 1998-1999 and need to replce the rider´s right footpeg.I ve seen some tutorials on youtube, and most footrests have either a coter pin or a U shaped o-ring to be removed  to remove the bolt. However my bike has none of those. There are some videos where bolt is cut with a saw. Is that the way to do it?
Also, are there any videos or tutorials on how to replace the brakes pads on this model?ThanksMiguel
