Thread: Brake booster

Tweet

Have a 2003 chevy silverado. The computer says SERVICE BRAKE BOOSTER,what does this mean,do I stop driving it ,is this serious?

Any malfunction of the braking system is potentially dangerous Frank, have it checked out immediately.

That model has an extra vacuum booster motor on the system. Here's a link to an answer that goes into lots of detail about how it works, what the code means, and several different things that may cause the code. Scroll down to #3

still working on 2003 chevy siverado,has anyone worked on the break booster? any tips for repairing it outside of a shop. if you took it to a shop how much did it cost. right now i am still driving it with service break booster message on. have you heard of any recalls on this. on one trip the speedometer was not working, now it is working,could this problem be related?

Frank, have you googled 2003 Silverado brake booster, or 2003 Silverado Recalls? You might be surprised at the mass of information out there in vehiclde specific forums.

Frank,there is a G.M. srevice bulletin on this. Bulletin # 02-05-23-004
I would post it up for ya but it is 5 pages long and I'm sure its copy righted.
The short of it is intake replacement for a vacuum starvation and re program the instrument panel. You could do the intake yourself but usually you'll hafta take it to the dealer for the reprogram. also says you'll need a new owners manual after the re program ??
part numbers on the intake are 89017230,throttle body gasket 17113561, intake gasket 17113557.

I did check on recalls and there is a recall if it is equipped with a hydra boost system.
