Frankenbrakes and brake improvement discussion

Following up here. I have Magura's so I can't pull the pads towards the rotor because magnets... However pushing the rubbing pad with a screw driver with a flathead towards the caliper and pumping the levers did the trick and took care of the pad rubbing.
Awesome suggestion! Much appreciated
I took apart my Sram DB8 and measured the largest OD of the Teflon peace holding the master cylinder seals and it was 9.45 mm. I do not have the tools to measure inside the cylinder.
Close enough to dare to assume that those DB8 have the same bore diameter as the other sram brakes at 9.5mm
Awesome, let us know how she goes!
She went well!
The hose did not separate from the lever body and I didn't die
Power was good but I had an episode where the bite point shifted closer to the handlebar after a rowdy ride trough a rock garden. It's corrected it self with more rowdy riding. Maybe It was some air in the system. I missed having tool-free lever reach adjustment in this situation.
It worked but comparing it to a shigura setup it falls short for me. Only advantage is the ability to have one spare lever for both front and rear brake.

Sram fittings compressed on Magura hose. Looks better than the shimanos that I have seen..

Another quick note on Hope quality: finally got my rear T4V4 brake back from their warranty department after almost two months of waiting, with a replaced MC and serviced caliper. Apparently the MC issue had something to do with a faultily set up CNC machine, affecting quite a few brakes. Anyway, three rides in, still seems ok.
But now the front caliper has crapped out. Howling, no power, and, of course, small drive side piston leaking leaking leaking. British engineering

Do any of you run (or have experience with) 2.3 mm wide rotors with Shimano brakes? I have heard conflicting things. Would love to hear your thoughts.
I currently have TRP 2.3 rotors on the RFX paired with XT 8120 brakes. Very little lever throw, they actually feel really good, but I have no idea how they'd perform over long descents, if they'd rub, etc. I have XT rotors for this bike (which is for sale) just haven't swapped them on the wheels yet.
Couple of my mates now running those Alixpress brake systems on trail and XC bikes (~$160 pair delivered). I'm genuinely impressed by the quality and performance of the things for the price. They use Hope E4 pads and common bleed fittings.
If you need a set of brakes for cheap they're worth looking into. Their power is on par with the Hope E4, so probably best for XC applications etc, not for full on Enduro/DH or big descents. And the colours look awesome

Just chiming in with another vote for the TRP DH-R EVO's, at least as far as initial impressions go. Just put a set on my heckler and so far I've been super happy with how they compare to the Code RSC's they replaced. I went with the 223/203 rotor combo and the amount of power, control, and consistency is super impressive. Only time will tell how they hold up over time, how often they need maintenance/bleeding, etc., but so far I am pretty damn stoked. 
Why would you want to do this? The master caliper area of the MT7 is ~87 mm² compared to 64 mm² of the DRT's. And the slave piston area of the c41 is smaller than the MT7's, you would lose a lot of hydraulic leverage and therefore power. The other way round is what a lot of people are doing, which results in a very powerful brake.
I can guarantee you that the DRT lever is way nicer in reality than all stuff Magura makes.

Just my opinion obviously, I'd never considered that people would want the Magura for aesthetics. I might be alone on that one this, but personally I'd always thought literally every other brake on the market has a nicer made, better looking lever than Maguras do.
Magura levers are flexy as fook and use plastic bolts. 
Can one buy just the Maxima levers? Asking for a friend.

I'm not sure, my 2 mm Formula monolithic rotor fit with not much air left when I had new pads installed. TS sells a 2.05 mm rotor so that's a given. I'll check the German forums and report.
Edit: seems to work, people are running this combo

to me it appears an awesome powerfull combo, isnt it ?
IMHO power is not directly dependent on or a result of rotor thickness. Heat management and stability are the main reasons for running thicker rotors.
The sense of increased power might come from the shorter lever throw. I went from 1.8 to 2 mm thick rotors and the shorter lever throw definitely made it easier for me.
But as you said stability is one of the main reasons (for me at least) for running thicker rotors. I changed mine because the Formula I had before got warped and distorted at their own will.

I'm pretty sure pads wear by more than .2mm before needing replacement.
So, remember when every jackwad with a CNC lathe pumped out any old thing?
Is this a modern version, or are these the dog’s bollocks?
I mean, 13%!!!

Can't be worse than Shimano calipers so it's probably worth the three hundos.So, remember when every jackwad with a CNC lathe pumped out any old thing?

I need new brakes for next budget project. Have some 1st gen Code calipers laying around (both levers are dead).
I want to use Deore levers and bleed it with DOT 5 silicone based oil. I've read a few threads (not very common solution) that it works, and ppl had no problems during months of use. Deathwish much? Change my mind.

Yep, I speak from experience.
Relatively weak, could never get good power out of them, except when they started the turkey-warble and extreme vibration thing, then I basically couldn't use the brakes because the vibrations were so bad I'd lose control. They just basically sucked at the whole braking thing.
Not a high bar.They still seemed better than Elixirs.
I used to have to bleed mine halfway through the day at Diablo and those aren't even long runs. I think I warranty claimed on them a couple of times and sold them the final time.
I can't recall what I went to...
