I don't think Brammo manufactures their own brakes.
I assume the Empulse rear brake is shared with the Enertia, single-piston Brembo. The front brake has gone from a dual-piston single rotor Brembo on the Enertia to four-piston dual-rotor Nissin. Presumably they changed manufacturers when they went to a higher specification brake set for performance and/or cost reasons.
It is indeed a little odd they would use two different manufacturers for the brakes.
It looks like the Empulse uses the same brake setup as the 2009 Triumph Street Triple R.

After a few hard stops, the brake pads did finally bed-in and performance improved significantly. As the bike sits now, the brakes are more than enough power to flip you over the handlebar, fortunately there’s also plenty of feel so fast, rear-wheel-in-the-air stops are simple and fun."
