Having some issues with my brakes lately (https://www.dieseltruckresource.com/...l-t313927.html).
On one of the zillion threads I've been reading through about folks brake issues, I saw someone mentioned that the screen in the master cylinder return line might be clogged and needs cleaned out.
Where is this screen located? And if I crack it open, I assume I will need to bleed the entire system out right?
