Questions on Brake Upgrades

[Surf Moia]

I have a 2014 SMB on a 2013 E350. I’m the second owner, and I’m really confused about the spec’s provided by SMB. It has a Dynatrac Front Axel (Pro Rock 5500 lb Rated). The spec’s for the front brakes show:

Brake Calipers/Pads: 2008 E-350
Brake Rotors: 1995 - 98 Ford F350/Auto Specialty AR8553/Dynatrac #DA601125-D

There is no spec’s for the rear brakes, so I’m assuming they’re 2013 E350.

First question, does this all sound right? Next question, I’m approaching needing to do a brake job, the current system is not great, and I’m looking for recommendations on upgrades that would improve the performance.

I’d appreciate any advice. Thanks.
