You do need to get the pipes in the right holes. If you don’t then you won’t be able to bleed the system. To check after you have installed the pipes open the nipple on the outside of the calliper and ignition off press the brake pedal. If you don’t get fluid or can’t get pedal down you have them the wrong way round.
if you open to top nipple and ignition off press the pedal and get fluid that also shows they are the wrong way round.
