anyone use the plastic chocks to help bleed? or do they take the chance and just leave the brake still attached with disc and pads all assembled?

wanted to try bleeding some of my brakes like this fella (mounted on some spare bars on a bike stand):

but this chap has one of them yellow chocks (which dont seem to exist)....

is there anything lying around the house that i could use? i got some plastic glazing window packers like these:

I do; I remove the wheels and the pads and pop the little blocks in between the pistons. If you don't have the yellow blocks, use whatever you have.

I use avid pad spacers:

I say that, when i bleed i use an old set of pads then let some fluid out when i push the pad spacer in after changing pads to new set.

I've got the propper shimano bleed kit which clamps onto of the Master cylinder which makes it a bit easier as you don't need to work 2 syringes at the same time. But the bleed method is exactly the same.

The method works spot on though just make sure you've got plenty of oil available. IMO the creation of the vacuum is the most important part to make sure any air is out of the caliper
