SOURCE: power steering problem
There is a recall on a steering problem for this year,I own the same year and remeber getting something about this in the mail. Call your dealership and it should be free to fix.

Ditto to the above poster. Your brakes work off the hydroboost from the powersteering pump. There is no brake booster per say. There is a recall on the brake system on certain HUMMER's. Not sure what year your's is but maybe worth looking into. This is for '04-'05 HUMMER's.
