Twin discs up front?

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

Yes Sir. That´s what I wrote:
and a bigger master cylinder (15 mm)
The 15mm is for dual caliper the size we talk about. A small caliper on the sidecar could do with a 15mm as well, a 16mm (or 5/8") will be a tad too big
owned bikes: 93 Ural rig domestic model, 95 Suzuki DR 650 RSE, BMW R100GS, Suzuki GSX1100G rig, BMW R100R rig with Ural sidecar, Ural rig with BMW drivetrain under construction,

Take a look on the lower mount of the caliper holder, where the axle goes through. If you make a new holder, it must be the same type of construction (the caliper [holder] must be able to rotate around the axle)
Yes this has a rotating bearing, or at least a bush, against which the spindle can be tightened, but leave the plate free to rotate. As a project this is looking complicated and expensive. A second caliper, second rotor, new master cylinder, all the pipes, fabrications, yaddy-yadda .. :(
