HAMMER DOWN!
Today on my way to work i glanced up into my review mirror. i saw out of the corner of my eye a red light pop up on my dash. i looked and it was my red brake light. by the time i looked down and saw what it was it went out and never came back. my stopping power never really changed, but the firmness of my brake pedal increased a little bit. i am sure some of you remember all the brake problems i was haveing a few months ago. my pedal has always been soft, but the braking power was never in question. today when the light came on the pedal feel became what a normal pedal would feel like. i drove for a couple more miles and stoped at a stop sign and stop light and then my "normal" pedal feel and brake power came back. it was fine the rest of the way into work with no light coming back. everything was fine coming home as well. i checked my MC fluid level and it was right up there.
I don't know of any vacumm pump history on my truck but does my symptom sound like a dieing vac pump? is there anyway to tell if the original vac pump is still on the truck?
When i had my truck in school my teacher hooked up a vac tester and said it pulled 25 inches at idle and held steady.
Another thing....When i am coming to a stop if i hit the brakes the pedal is soft with decent stoping power. if i let off and hit it again right away the pedal gets firmer by quite a bit and the brakeing power goes away by a noticable amount. if i keep pumping the pedal it gets harder and harder and brakeing power goes down and down. if i wait a few seconds between pumps then everything is "normal'.
Thank in advance.
