03 Silverado Z-71 Brake Booster

[quote:5a4ce9d59f="julie702"]my truck just popped up the DIC message Service Brake Booster. Is this something that I can change or does a mechanic shop or dealer have to do this?? and how do i do this????[/quote:5a4ce9d59f]

When it comes to the brake system
U should have a shop /dealer look at it especially if not sure of what need to be done
Safety is first
As far what u should check :
the fluid
Open hood check all fluid and brake fluid too
Look to see if u notice any out of place
Good luck
