I am sure this has been talked about before on the boards but I wanted to go over it in more detail as to exactly what the cause of it is. You may only experience this is the morning and may think nothing of it but in reality it is a very dangerous and expensive repair. Take a look..

 

Hi & Thankee fer this info - and all of the other info you have graciously shared here.

Congrats on yer New Title !!! Well-deserved!

 

Agreed. This guy is the man.

 

Awesome videos man thank you for having a non bias straight forward approach.

Noticed that the new one is now plastic. Probably what the old one should have been.

Can't believe that they don't run into these things during their testing. So much for tearing down everything jeeze.

 

excellent video and description.

To be clear though - you still have brakes even when the vacuum pump fails. You just have no (or very little) boost from the vacuum booster. You will still meet the FMVSS stopping requirements for a non-boosted stop.

And for the change to electric vacuum pump. It was surely driven by the need to increase MPGs. A cam shaft driven vacuum pump runs non-stop (when the engine is on). This one only runs when needed so there is less energy consumption.

Any idea when they changed to the plastic pumps???
I have a 2012 EB... I'm hoping I might already have the improved pump!

 

Wow I didn't even notice till you said something.

I don't think they ever did, I think the revised plastic housing only comes as a service part, in 2013 they went to cam driven pumps.
