I'm about to change the rear brake's on the octy, have been told that I should replace the caliper guide pins when I do it.

Would you? I didn't need to on the front, just cleaned and threadlocked em.

After some opinions.

Intrested to know how you get on with changing the rears, mine needs new disks and pads on the back but ive been putting it off due to having to wind the piston back into the caliper, heard of some people having problems!

Was fine when I replaced the front pads and discs. Just used a G clamp to wind it back in

You need a windback tool for the rears, they screw back in, so you can't just push them back in like you can with the fronts.

As long as you wind the piston the right way, rather than winding it even further out, you will be OK.

so what would your opinion be on the guide pins then?

Hi there, You don't have guide pins on the front calipers. The guide pins are on the rear calipers as the caliper is a floating type and the guide pins are used to allow the caliper to travel back and forth with the wear on the pads.

Typically the guide pins do not need replacing unless they are seized or pitted due to lack of grease on them. This is what makes the caliper seize as when the guide pins become dry they can not travel freely.

You can check these when you have the caliper removed

You can remove the rubber seal and pull out the guide when you remove the 13mm bolt and then check them.

Yep that is corect you do need a wind back tool only for the rears, however this is easy to use and can be bought from most motor factors quite cheap. I have used mine number of time and very straight forward. It is almost impossible to do the job without one

Sorry buddy please don't mislead the OP, it won't be fine on the rear and if you attempt to use G clamp on the rear without winding or turning the piston round, kiss goodbye to your capliers..
