When trying to get all four pistons in my Guide calipers to pump evenly, I struggle to keep the freer ones from moving out further than the stickier ones. I was thinking whether some mini woodwork clamps might do the trick to hold the freer ones at bay but the smallest clamps I can find still look too big to fit. Does anyone share this need or is it just me?
Tie wraps (cable ties) can work or a suitable sized Allen key wedged across. Hope this helps.

You need a bleed block with one section ground off it to allow just one piston at a time to move.

What they said... works like a charm!

High 5 sir! Love it, ordered. What would I ever do without STW?
I 3D printed one which works perfectly. I’ve also used bits of scrap wood in the past (well actually a wooden clothes pegs that I took apart).
Another vote for r3pro, used mine just the other week.
Will that r3pro fit Shimano 4 pots?
Fab. thanks @jordan 👍😎

It looks like you can only free one piston at a time. So if you have two stuck pistons, is the best way to do each one separately?
So, you move the pistons back manually (normally a flat bladed screwdriver forced in between old pads and rotated), then remove pads and stick this in the gap. Do you then squeeze the lever and let the piston move out...does it stop it falling out?
You then work that one back and turn block round and do on the next piston and repeat for the other 2 - is that right?
I'm needing to change my rotors and pads so it might make sense for me to give the pistons and movement and reset at the same time.
The alignment tool - anyone used that? How close does it get everything to the rotor?
I've got disco brake pads and they seem thicker than others so as much as I'm wanting very little lever pull, I'm wanting to make sure there is space to move the rotor without the pads touching it, so assume alignment will be centred but does it also get the pads/pistons moved as well?
