I hate to say it the ATE calipers on the R90/6 are a bit fussy to change pads on, there is some messing needs be done with an adjustment bolt to get the pads properly seated and so they work best.
The good news is, it is not impossible nor does it require any special tools. Once you do it, you won't have a problem again. St.

Re: R90/6 brake pad replacement
As far as bleeding, if you are going to do the squeeze the lever and crack the bleed nipple method, avoid pulling the lever all the way to the handlebar. You will be dragging the internal rubber seal across potentially rusty or rough spots. Secure a piece of wood to the grip which will limit the throw of the lever...that throw should be about your normal usage. Then pump away and flush old out and new in. Then after that, pull the lever back to the piece of wood or to where you now have firm pressure, and tie it up for the night. This opens the internal valving and lets any trapped air bubbles come up and into the reservoir.

Re: R90/6 brake pad replacement
One reason may be air in the lines, bleeding will remove it, I will bet Brook has a video on how to do that.
Second, depending upon the age and miles the environment the bike has been in, the front flexible brake lines may just be shot. The original lines in time were prone to flexing. One of the first improvements I have done is to ditch the stock lines and replace them with stainless units.
Oh as a final thought, don't forget to make sure your brake cable from the handlebar to the master cylinder is properly adjusted.
Hopefully this helps, Cheers, St.
