Basically all i’ve done is removed the original Honda caliper then tapped the original mounting holes and fitted two heli coils to make them the correct size and thread. Then bolted a 10mm steel plate to the original mounting holes, drilled and tapped new mounting holes in the Subaru caliper bracket, machined the discs and also filed 1mm off the subaru calipers so that they now fit over the original Honda discs, and ta da … subaru calipers fitted to a honda 🙂
In case you haven’t worked it out, the handbrake on a Subaru Leone works off the front wheels were as most handbrakes work off the rear wheels and usually use non vented discs. The bonus with the Leone calipers are that, because they are front brakes on the Subaru they run on vented discs just like the front of the Honda, which also means they are of a good size to help pull up the pure power of a 5 cylinder fuel injected trike hehe.
Part of the certification requirements are that any critical part of the braking system that is welded must have a ND certificate ( non destructive cert) which is basically getting the welds crack tested or x-rayed for imperfections. So rather than go through that hassle i’ve designed the brake system so that nothing is welded, which was a long way of doing a simple job but it removes the hassles at certification time.
