I've just changed the pads on my 2008 Juicy 7's. However the front lever is now spongy. It was fine before hand and the lever is now coming all the way to the bars. I've turned the pad contact dial all the way in to no effect. I've pumped the lever loads to no effect. I'd think bleed but they were fine before the pad change.

Any suggestions?

did you change the pads with the bike upside down it might have caused an air bubble

BM5 if you look back at my thread of a few weeks ago on the subject.........make sure you watch the youtube vid on how to bleed them.  It makes what appears to be a dark art quite understandable!

as a side note, have your old pads worn with a slight taper or is there even wear across their surface?

the reason i ask is cos if the caliper is slightly mis-aligned and you replace with new pads that are flat, as they touch the rotor you'll get a soft feeling at the lever, ie the two flat surfaces will not be contacting squarely.

edit: hope that makes sense, i can describe it in my head but putting into words is another matter

if the pads haven't worn evenly then it could either be an alignment issue or sticky piston.

for alignment, the tri-align system is not the best and yes, greasing the concave washers (a tip from Dyl) does help but it's mostly trial and error. ideally you should aim for a solid and snappy pad contact. achieving that usually involves manipulating the actual caliper, rather than applying the brake, then slowly tighten the two bolts in an alternating pattern.

for a sticky piston, determine which is at fault and smear a small amount of brake fluid around the part of the piston that slides, apply using Nobby's technique - a cotton bud, removing the pads first of course
