Re: Wierd noise while driving
that diagram is courtesyt of krayzie. he posted it a few montsh ago and i saved it. as far as weak vacuum goes. it'll just make it harder to press the brake pedal. it wont do much to gein you stopping power, it just helps you so you dont have to press the pedal so hard.
#40 does look like teh prake pedal sensor switch. they go for about $10 at the parts store. they are very simple on the inside, but just a PITA to replace because there isnt much space around them. i have done it on my truck...just to find out that the old one was fine. there was a fuse i didnt check.
mike, replacing this will not turn off the switchin the dash. i mean it could, but that light being on is generally indicating that there is a problem with the system....like the ABS isnt working, or low fluid...stuff like that
