P 32 Brembo caliper bleed position

I know that bleed nipples should be on the top of the caliper to get the air out but I looked at the bikes that use this caliper and it's sometimes on the bottom

What do you think? Can it have internals good enough to be able to push the air out even being on the bottom?

You might need to suction bleed the calipers instead of pressure bleeding them.

Not sure whether it would work well enough with the bleed nipple on the bottom. We run a similar caliper to the aprilia rear and we just take it off for a bleed with a plate between the pads.

Having said that, that bike simply looks like its been put together for show as you should be able to swap the bleed nipple with the brake line on that rear caliper.

Cheers,
