Magura MT5 just won’t stop, recommendations?

[JMath]

I have some Magura MT5 brakes that came on my Husky HC1, when new they were ferocious stoppers, I had to run the softest tread compound to prevent sliding the back tire going into every berm with only slight lever pressure.
Over time they have become incapable of doing such, I’ve swapped pads, brand new discs married to brand new pads, MT7 pads, and can’t seem to get anything decent. I did run into and issue that the Husky suspension loosened the banjo fitting on the caliper during cycling through the stroke, contaminating the first pads and discs. I’ve pretty much determined you cannot resurrect pads and discs that have been lubricated by mineral oil, heat, soapy wash with Dawn dishwashing detergent, bead blasting discs, nothing has returned that original bite I had.
I can bleed the system and get a wonderful firm lever , no mushiness at all. Every once in awhile I loose that and have to rebleed. Originally blamed the banjo bolt loosening but now I routinely check it before rides. Could I have damaged the master in some way by pushing back the pistons without opening the port at the master cylinder? I may have done that early on during my first pad change. But lever does always bleed up as firm as any Magura I’ve had and stays that way for several rides.
I feel that I am actually done with self lubricating brakes, but really don’t want to just pitch these brakes that were so incredibly strong from day one.
My front brake does well, occasionally has either lost bite or developed squeals but I’ve been able to get it working acceptable, but maybe not as strong as originally was.

Considering my options:
Replacing master cylinders with Original MT5 Magura
Shigura setup if I can verify that caliper banjo loosening is no longer occurring.
Maven Base as they have ferrule connection at caliper preventing unwanted loosening, but still self lubricating brakes.
Dominions, with a rerouted brake hose to eliminate suspension torque on the banjo bolt. Bonus here is DOT cleans up so nicely with water, and the water splash on hot brakes makes them really strong.
If your car or motorcycle had brakes that were 1/10 as maintenance intensive as freakin’ bikes there would be mega class action lawsuits everywhere!

I have Magura MT5’s on my e-mtb and now have about 5,500 miles on the bike. My best suggestion is replace the Magura brakes and go with a different reputable brand. Magura’s are just not worth the hassle and issues.

Swapped to Dominions
A lot of work but absolutely worth it.
I’d say response and power spot on now.

Really should have swapped to external cable routing at that time, couldn’t find decent zip tie cable mounts at a good price when I did the conversion.
