To start things off I just completed my Firebolt to Lightning swap. I traded rear brake reservoirs so I'm using the correct one with the lightning tail and now I have no rear brakes. All I did was swap the res and bleed the brakes. Befor the peddle was firm with almost no movement before the brakes applied. Now the peddle is as spongy as all hell and even after running a whole bottle of dot4 through the system with the caliper in every position possable to try and bleed air out I got nothing. When bled off the bike with a spacer between the pads it's har as a rock....... As soon as its bolted to the bike it reverts back to the sponginess. I also noticed the caliper moves around when the brakes are applied. I've spent about 4-5 hours messing with it to day and I'm exhausted. If anyone has any tips please share. I will also say this is not my 1st rodeo bleeding brakes and this is beyond anything I've encountered.

I know the rear brakes can be funky as hell. I used a mighty vac and reverse bled them by sucking the fluid from the caliper rather than the standard pumping the pedal.

Well line expansion is out. How many miles you got? I did I master cylinder rebuild when I switched mine over. Cheap insurance. Did you look at your reservoir line? Chance that it kinked?

After my third time watching the video can you take a few pictures. Something doesnt look right to me but I cant tell from the angle
I actually had this happen on a car once, it happened because i tightened one caliper bolt almost all the way then did the other. I just had to take the bolt back out and tighten a little on each bolt back and forth untill it was tight. Hope this helps. Slides might need more lube too, but the caliper i installed was brand new and i lubed the hell out of them before this happened to me.
Plenty of lube on the slides. The front bolt on the caliper apears to have been cross threaded at some point ( before i got the bike) and it's putting the caliper in a weird position causing the piston tone forced back in a lol bit ..... Therefore giving me a soft Petal.

do you have a thread chaser and or tap? if not what is cross threaded? the bracket?
The front floating bolt/pin that holds the caliper to the swingarm bracket. The threads in the caliper seem to have been cross threaded to the point that the head of the bolt does not stir flush against the caliper when threaded all the way in. Therefore it puts the the caliper at an angle when the pin locates itself in the swingarm bracket. I'm thinkning of helicoil or timesert before I go getting a new caliper....... Possibly even doing the hidden caliper.
