have you checked basics before prop valve,i think prop valve would alter balance front to rear .not left to right.

had a near 40% imbalance at last wof, new pads JUST scrapped it in. Have just fitted bigger calipers, disks (machined), and new pads. the imbalance is the same wheel that was out with the old calipers, pads and disks.Thinking of swapping the front left an right brake feeds at the abs unit to see if the fault switches sides, im guessing the proportion valve is in the abs unit now

the bigest problem is no one changes brake fluid after 24 month this is where all them problems originate from.

I'd pull the fuse on the ABS (not being familiar with the model I'm presuming it to be the easiest way to disable it) and try it on the rollers again. let us know how you go and we can suggest the next step in diagnosing the problem, I'm picking it's probably not an ABS fault.

Some dual line brake systems use a left front/ right back (& vise versa) cross over system

will do sr2.
Mr fix, it's 3 a 3 channel system, 2 lines come out the master cylinder, both these go directly into the abs unit. exiting out the abs unit is 3 channels, one for both rear wheels, one for front left and one for front right

So if there's ONE brake line going to BOTH rear wheels. Then they will be getting exactly the same amount of brake pressure! If you have just fitted new calipers etc. I'd go back and check all of the slides and pistons etc. then rebleed the whole braking system.

also check the integrity of your hoses.I had one once that had a weak point and was ballooning under pressure!

oh crap, it's only the fronts that are not balanced, totally missed that in my orig post!

Well the rest of my post still stands. Check slides and pistons. Then rebleed te brake fluid. A pocket of air on one side will compress giving a lower reading.

maybe air, calipers are 4 pots so no sliders, just seems strange the same side is down the same % as the previous caliper on the same side

That could indicate a partly crushed line& maybe a bit of grit floating around that spot. OR a partly collapsing rubber pipe as above effect
