Brakes Making Weird Noise! Help Please!
Just yesterday I noticed that when I depress the brake pedal my MOTOR seems to lug. It really only does it when the motor is warm. Even when I'm completely stopped it still does it but when I let go of the brake pedal, it goes back to a normal idle. I didn't know the brakes had anything to do with the motor. Any help would be greatly appreciated. Thanks!

Could be a vacuum leak?

Perhaps. Probably has something to do with the vacuum between the booster and the intake manifold.

When he said that he let go off the brake pedal it went back to normal so I said, you have a bad brake booster. Get a replacement.

I'd check vacuum lines before replacing anything could be a simple fix...

How do I check for a vacuum leak? If thats not the problem then I will look into the booster. Thanks for the help.

No, no...it's the idle valve set too high. Read this thread. Very common.

Is adjusting the idle a easy thing to do?
