I have yet to build my trike, But over here to get it legal for the road it MUST have a mechanical hand brake as fluid lock can fade quite bad (A call to the man that will give it its certificate confirmed this)
Because mine will be built from scratch I am using car stubs that have cable and fluid disc brakes.....But I guess adding a mechanical second brake to the disk would be a PITA
