I have a 2004 dodge ram 1500, 5.7 hemi. I just finished installing new valve springs on all 16 valves. I went to take it for a test drive and discovered I have no brakes. Stepping on the brake peddle is like stepping on a brick, I can barely push it down, and when I do get it to go down there is little to no brakeing.
I noticed the vacume connection at the booster has two places for a hose to connect, the large hose to the intake is connected, however the smaller connection is open. I seem to recall a cap being on the smaller side. I can't find a disconnected hose so I'm guessing this smaller one should b capped.
Does anyone know if it should be capped, or am I missing a hose?

 

Probably a cap would give you brakes back, and make the engine run a little better. That's a significant vacuum leak...... Check the emissions label under the hood, it should have vacuum line diagram somewhere.

 

 

I put a cap on the open side of the connector and n change, I think I can here a vacume leak so I'm trying to track it down.
I'll let you guys know what I find
