ok so if i speed up quickly the brake light goes out
as soon as i let off the gas the light comes back on

then after a while to goes out again

all the lights work ive had my friend drive behind me


then this morning my batt light came on

so im thinking that the alt went out


the power steering pump was replaced by the original owner but not the alt

so im guessing after 14 years it punked out

so i need advise since i dont want to be stuck on the road

1. Check the level of your brake fluid. If its low, fill it. The brake light should go out. Check your pads before you do this because it might be time to replace them.

2. Go to an auto parts store and they will test the batt and alternator. If you need brakes you are already there so pick some up.

nope brake fluid is fine cheacked that too and added extra just to be shure

ok ill have the alt tested ill have to wiat till i have a day off thnx for your imput very helpful

Next thing you can try is checking the sensor on your ebrake. Those are the ONLY 2 things that will trip that light. I'm surprised that it wasnt the fluid. The way you explained it I was sure that's what it was. If its not the ebrake sensor then its a bad sensor in the fluid reservoir.

Anyway, it wouldn't be the bulbs themselves. They wont trip the "BRAKE" light. There is a separate warning light for those.

My money is on the alternator since it's a 400, and the power steering pump was replaced. Probably had a bad leak right onto the alt.

good call.....at least the parts stores will usually check them for free.

yepp thats why i thought it was the alt cuss i read some where that they do leak on the alt.

ok so im almost positive its the alt cuss i ran out and looked under the car on my break at work and the alt is covered in dirt build up from that old leak from the power steering pump

Might just want to replace both depending on how old your battery is.

Do not over fill the brake reservoir! If you are up to the Full line keep it there. There might just be a loose wire to the sensor since it affected by acceleration.

oh ok i wont fill more then ill cheak the harness when im on lunch
the batt is only 3 months old (ill cheak that later too)

Then Id say its definitely NOT the battery. Either way get them both tested at the parts store. If the battery is shot Im sure you'll have a warranty on it. You live in a warmer place so Its not likely the fluid level in the battery was affected by temperature.

ok thank you every one so the problem with the brake light was the connector to the tank

and my alt is out

if brake fluid is good to the top, then it can very likely be a weak or going dead alternator.
Happened to me before on my other car, and out of nowhere, car died on me.
