The sensor for the bike warning system.

I am a fan of this lube.
Caution!!!! use only in the proper spots and be very careful not to allow it to get anywhere else than where you want it.

I put it on the back of the pads where they contact the pistons and VERY CAREFULLY on the other moving/contact parts of the pads.

>>>>>>>Do not let it get anywhere near the friction material or brake rotor!

All ready to install on the bike!

All done!!!

I use a witness sealant found at: http://rshughes.com/products/021200_20193.html
so I can check these bolts on my pre-ride walk around quickly. This stuff doesn't hold the bolt in any way, shape, or form. (That is what the LocTite does) It does allow me to visually check that the bolts aren't backing out. The torque isn't very high, (24 NM) so make sure to use Loctite.

And there you are, a twenty minute job at worst, if you have the tools you need out and don't run into any problems...
