Just wrapping up a disc brake swap on my 40. Everything is new Vac Booster, Master, lines, calipers etc.
- Engine hasn't ben started since new swap has been completed, so nothing has had vacuum applied
- Booster has a new check valve, and hose to the manifold
- When I press the pedal, I hear the moaning and feel vibration in the vac booster hose.
- Thought maybe bellows were causing it, but I pulled them forward onto the rod, to they arent contracting or expanding.
