Question Brakebooster pushrod adjustment?

Hi does anyone know if the brake booster pushrod of a 2004 WJ is adjustable? My pedal sinks almost all the way to the floor before the brakes take.

There is no air in the system. That has been confirmed by a mechanic. Just thought I'd put that out there to avoid a bunch of replies mentioning it.

Thought I'd ask before tearing into it.
Thanks!

Did the mechanic check the abs system? There was a post the other day where a guy just changed his rotors and pads and, I think topped off his mast cylinder with fluid, and somehow got air into the abs system. His pedal sank abnormally low and even though he had flushed it over and over, the air in the abs made the pedal sink. Don't know how to check it though, hell, don't even understand how the abs is tied in...

How do you know there's no air in the abs....without bleeding with the factory drb unit it's just about impossible to get air out of it with a conventional bleed.....the fluid will come out of the caliper air free but it will still be trapped in the abs. About the only ways a pedal will sink is with a faulty brake booster or air in the system.

If you can't fix it with a hammer, you've got yourself an electrical problem!

Here is the thread about it.

It seems he activated the abs unit a few times on jack stands to bleed the system. Might want to send him a pm for more details.

No air.
I can kind of hear the pushrod making contact when the pedal becomes firm.
