I notice the db br 612 when on curve is noisy around it trucks,it's sound like the brakes might still be on or is has something to do with the tilt function so is this normal or a known issue?
If you refer to the (overdone IMHO) flange squeal of the BR 612, it has been discussed on some threads if memory serves correctly. Without any fixes or patches, though. (No surprise here) https://forums.dovetailgames.com/threads/db612-is-this-prototypical-behaviour.51875/
