Re: Brake pad replacement
Those rubber concertina boots are the seals that go over the caliper slide (guide) pins, to be honest I wouldn't bother changing them unless the old ones were damaged in some way.
In my experience it isn't necessary to replace the slide pins, however they can become seized causing the caliper not to slide freely but cleaning them up and re greasing is normally all they need.
When you remove the old pads if one is worn down a lot more than the other it's quite often a sign that the caliper isn't free to slide on the slides, even if the old pads are worn equally do check the sliding operation of the caliper.
Take a good look at the brake caliper set up before you start so you can see how things go. Only strip one side at a time so you can use the other side for reference should you need to.
Take a look at the link below, it's a "How to" that Lagtdi posted on changing front brake discs and pads, as you are only changing the pads just ignore the disc changing bits.
I'm not sure if your brake caliper set up is the same as the one in the link but it will give you some idea.
