Is it on a bike with full internal hoses?
If not, I'd consider going to cable brakes with some hybrid calipers (because plain cable disc calipers are a pain in the arse with the constant adjustment). If they're a thing in flat mount, which you probably have....
Might be a tempting option after all that hydraulic hassle. I was a hydraulic service technician, and I gave it away because hydraulic shit is a nightmare.
(Those nifty hybrid calipers excepted, since the hydraulics are self-contained)

Shifter question...
My right hand Ultegra r8070 shifter is probably dead, according to my LBS. Won't bleed. I suddenly lost braking power on both brakes a couple of weeks ago. Right hand brake has always been a bit dodgy, a little bit of travel in the lever before anything happens but it's something I am used to and most of the time doesn't affect the braking. About once a year or every two years I experience total brake loss in that brake and normally a bleed solves it but this time it doesn't want to know. My LBS are planning to strip the shifter to investigate but the mechanic says this is a crappy job he doesn't really want to do. I'm happy to pay for it. Anyway...
In the event this shifter is fucked, what are my options for other repair or replacement? I can't find a right hand r8070 shifter available anywhere. Do I really have to buy a set? Even second hand they are really spendy aren't they. Honestly I would rather the frameset fail than a shifter. Bike was bought in 2019 so well out of warranty.
It would be fucking weird but what about one Ultegra and one GRX shifter?
