Hi guys, having a bit of a problem with my brakes and am struggling to find out what's wrong. I have no servo assistance at all and it's scary

I have taken the vac line off and it is sucking but not very much eg if I sealed the end with my finger and left it it would fall off under its own weight. When connected I cannot hear any air escaping from the servo. Does this sound like a vac pump or servo issue?

Sounds like your servo.

BTW you don't get pressure from a vacuum!

Look for cracks NR servo
