Brake rod removal on a front disk set up

[ACUDANUT]

 I can't seem to get the rod out of the power booster.  On drum brakes they are easy and just snap in, HOWEVER  on a power front disc set up they seem to be locked in.  The one I have is too long of a rod and will not come out.  I am wanting just to change rod length's. HELP

Huh?  There is no "rod" on a power disc set up.   Under the dash is the bell crank set up which attaches to the rod that comes out of the power booster which is non-adjustable & non removable (unless you take the booster apart)

  It is inside the rubber boot shown.

Yes but it is non removable/adjustable...

The only adjustment is on the front of the booster...the rod that presses on the master cylinder itself....

Dang, I was hoping to put in a shorter rod (between/inside the rubber boot)

May I ask for what reason?....all the adjustment you will need is on the front rod.

Are you having a problem with the brakes?

 I was thinking of putting a later model power brake booster.  However, they have different rod lenghts.
