I have finally succeeded in engineering and modeling a direct caliper bracket for connecting a SN95 aluminum dual piston caliper to a Granada spindle. It took 5 prototypes to tweak the design and production. Much of the design work involved selecting a suitable mating rotor. The best candidate, from a mounting geometry point of view, is the Granada rotor. I will be able to produce a dust shield as well. I found though that the Granada rotor's disc is too thin, in that it is not massive enough to take advantage of the capability of the caliper. This rotor is also too thin to properly retain the pads within the assembly when the rotor and pads are at their wear limits. One or both of the pads could be ejected from the bracket/calliper assembly.
I see no point in offering a product with these limitations and decided to design an appropriate rotor. This slotted 11.06" rotor will have an integral hub and a 1.025" thick vented disc. The new rotor's disc will be about 30% more massive than the 0.88" thick Granada one. I am in the process of maxinizing the design of the caliper as well.
I expect product availability this summer. Pics below.
