I have the 3 abs bolts disconnected and have a (hopefully) repaired module ready to go in.

I need to replace my brake fluid so I was wondering if actually removing the lines to the abs and then reconnecting it all up and bleeding the brakes is going to cause a bunch of issues, or is it pretty straight forward? I can do the bending the brake lines method and not disconnect them just wondering which is best. TIA

 

I just bent the lines. Not that difficult and no bleeding required.
Like you, I was concerned about problems bleeding the lines if I removed them.

 

The official procedure is in the I found and put up in 6 parts very large 821 page or so X300 XJ6 - XJ12 Vehicle Service Manual , section 8 without looking up

On aircraft brake bleeding we had a flex hose on the bleeds that put into a U shape , when brakes relaxed it would not draw air back into brake wheel cylinders and up , but we had plenty of free brake fluid which was actually whole aircraft 3000 psi hydraulic fluid ( flight controls and gear extension )

I have not bleed brakes on the X300 , but all I heard from my never helping neighbor was excuses not to work on it and not solutions , he made his living as a mechanic somehow but all I saw was a wrench bender with no thought or reasoning
