I may be missing the obvious, again but what is the purpose of the brake pistons with the + on the end. Le dude says they must be lined up square with the caliper, but why. The one on the back caliper of the Burgman I think is the piston the operates the parking brake. But if I remember right there's one on the front as well, maybe something to do with linked brakes, I think, maybe I should give up thinking it dosen't always end well

I know some rear brake cylinders with parking brakes have screwdriver slots on the pistons to screw them into position before the brake can be operated

This is something which I've learnt over the years - if I don't understand why someone who is more expert than me says to do "X", then do "X". If one day I can work out why X is the right thing to do, then great. The wrong approach is to not do whatever it was and then find out the hard way why it mattered

Not sure I've explained myself clearly but hopefully it made sense.

And yes, I did learn some things the hard way

I think your right though they are a bit big for a screwdriver, I used the pointy bits of an open ended spanner which seemed to fit quite neatly. I would like to know how to set it up properly, will have to have a look on you tube.

Yeah I do like to know the why's and the where for's and yes I have found out the hard way more than once
Thanks for the replies always appreciated.
