Extra part came with my new master cylinder?

[dkmcgowan]

I purchased a new master cylinder this weekend from NAPA, M2960.

 

It looked just like my original, bolted up, worked fine, everything seems good.

 

But...

 

There was an extra part included in the bag, it looks like the one below.  That picture is also from NAPA but it is a part included in their master cylinder rebuild kit.

 

What is this for and do I need it for anything?

 

It almost sees like it could be used to convert to work without a booster maybe?

That's a push rod from the master cylinder to the brake pedal. So the master cylinder M2960 you purchased probably has another application it can be used on besides Jeeps.

 

Or it's the new push rod you should have used.
