There isn't a tap on the trailer brake pipe by any chance is there?.. There was one mentioned in the manual for my old 620, but there wasn't actually a tap there.

I checked an there's not the manual doesn't give much help tbh I wonder is it a strip down job for maybe a valve stuck or something

Should just be the standard procedure , make sure fluid ( mineral NOT dot 4) is topped up .
There are bleeders at the master cylinder but you rarely have to bleed them, bleed the service brakes as normal .
Bleeder at the air brake valve ( if it has air brakes ) and bleeder at the hydraulic trailer brake valve .
check the bleeed screw not blocked .
Failing that unscrew the pipe onto the trailer brake valve and press brake if you get oil to the valve but nothing out the bleeder then issue is in the valve.

I know with car brakes sometimes it was best to loosen all bleed nipples until they drip then go and have your lunch .
As long as the fluid is topped up more than often this has worked for me even on a Landrover that the owner had the front lifted in the air for days as he could not get the front brakes to bleed.
