a slight idle problem with brakes!!!!

[accordtunerf22]

when im at a dead stop idling and i pump my brakes my idle will rise and if i pump them for a repeated amount of times the idle will jump but once i stop it will idle normal but at 1100 rpms... does anybody have an idea of what it can be?

Brakes use vacuum, vacuum is created by the engine.....

if your brakes are hard...its your vacuum assist most likely. Check your vacuum lines running from your booster to your check valve, and from your check valve to your intake mani, then check your check valve, then check your booster. IF your brakes are hard that is

try not to pump your brakes at idle. I first noticed this on my car and it thought it was wierd so i kept pumping them untill i found out that eventually this will cause your idle to bounce around and youll end up cleaning all of the valves and it still wont fix it... end rant/// or at least i wouldnt be pujmping my brakes liek that any more.

Doing that won't do any damage... Any issues you experience with idle are a result of something else. As said above, the brakes work with a vacuum created by the engine. When you make the brakes work, you make the engine work. It's normal.

mikes right (as usual) i've seen this in many cars.

yeah idle should be like 750 +/- 50rpm i think. yeah, double check all of your vacuum lines and make sure none of the hoses are pinched or whatever. Look on your plenum to make sure everything is connected there in all the ports.
