Service break booster?

  

jermacjr -> Service break booster? (2/16/2008 4:54:29 PM)

Whats up everyone? Bewby looking for info. I proudly drive a 03' Silverado w/ 48000 mi. Yesterday while going down the road i notice a loud buzz or hum that could be felt in the peddles coming from under the hood i pulled over and opened the hood and noticed the cylinder attached to the break booster buzzing. After about minute it stopped, but now every time i start the truck it does the same thing for about a 30 secs. I also noticed the " driver info center" on the dash says "service break booster" after the buzz stops so the ecm is picking up the problem. My questions are, Is the break booster servicable? I always thought you had to replace them when they went bad. Also what is the cylinder attached to the booster, and can this be replaced? The truck still stops fine so im hoping this a simple fix. Also has anyone heard of a break booster crapping out so soon? I'd just like to somewhat informed before i call the shop and they try to soak me for a new break booster. Any and all help/info would be much appreciated. THANK YOU.

i dont think you can service the booster ha ha, usually when they go bad you have to replace them, so are you talking about the master cylinder on the booster? the thing that holds the fluid ?

Well, its definately not the master cylinder, The cylinder I'm referring to is mounted on the booster just to the left of the master cylinder. It has a wiring harness on the top and what looks to be a vacuum hose coming from it. I'll try to post a picture. Thanks for the reply.

Yes, i purchased it used from a relative with 40,000 miles on it. It has always  been well taken care of.

You can go to http://photobucket.com/ and sign up for free. You can then upload your pics, after that it will give you four urls you can use (copy and paste) as a link in your post. Use the second url that way people can only see that pic not the entire album. like this:
