Brake Light On?

BT-22 · #1 (**permalink**) 02-25-2003, 09:03 AM

I just noticed this morning that my brake light went on when I hit my brakes a little hard.

I noticed this before they changed my O2 sensor but didn't think much of it. It seems to only happen in cold rainy weather that's the only other time it's happened.

What could be the problem?

It's only happened twice i the last couple of months. It doesn't happend when it's warm, I've tried it already.

Check your brake fluid level. The level is VERY sensative to making the light come on, even an 1/8" low can cause it to come on. Happened to me too, I added a little bit of fluid, no light since then and thats been almost a year ago.

Remember that cold shrinks, could be just enough to trip the light. Let us know.

yeah what kind is needed?

I checked mine at lunch and it was at the min level. I'm assuming that the level dips when I break plus the shrinking that SA talked about causes the light to go on!

Thanks for the replies!

Dot 3 according to the manual and haynes book!

I just got my haynes manual today looks pretty good!

Was dipping low when breaking so I filled up and no more light!

Thanks guys!

Glad you got it figured out. Like I said earlier thats what fixed mine as well.

Glad you reminded me, I need to order that Haynes manual, thanks.

A very good buy, the Haynes manual! Only $17 and it's light too. Has a lot of info and it's not extremely heavy.

You could do work at your truck and not have to worry about flipping through pages or dropping it cuz it's a little too heavy.

Good investment!

Like the picks on the back inside cover page with the picks of the different spark plugs and conditions that cause them to look like they do.

Very informative!

They told me that was a sign on my '01 that the pads were worn....sure enough about 2 months later they were gone.
