Did you not see the advice I gave to your previous question on the same subject?

the two threads now merged into one. DD.

btw, once you've confirmed you've read this, I'll merge this question with your original one to avoid repetition.

Yes i did but there was no mention as to why i have no brake lights which is why i asked again. Surely a faulty sensor should not disable them as this could be dangerous?
|
Dont know what has gone before but I suspect that it is either bulbs (one blown will not put the light on but both will) or the brake pedal switch.

Simplicate and add lightness!

Ive checked both bulbs,fuses & pedal switch, all are ok.
This has only happened since the abs light has started to stay on.

Speedemon,
Have you tried disconnecting the wires from the brake light switch and connecting them together to bypass the switch and see if the brake lights work at all?
If the ABS light is on, then there is a reason for it. The system has a fault of some kind, and in which case refer to my earlier links I posted for reference. Now it could be something as simple as a loose/disconnected wire, or at worse a faulty sensor. The sensor bodies are made from aluminium, and pushed into the cast iron of the suspension assembly. Over a period of time the aluminium can corrode and swells up, thus crushing the sensor and rendering it useless.
The first thing I would do is get the ABS *fault* sorted, and see if it also cures the brake light problem as well. The two are obviously connected if the fault light came on at the same time as loosing your brake lights.
btw, I've merged this thread with your previous one.

Further to my earlier thoughts on this, I\'ve just been studying the circuit diddlegrams for the Cavalier, and the brake light switch is connected to the ABS system in some way. I know you said there isn\'t a problem with the switch, but *if* it is faulty, it will activate the ABS light. also if both brake light bulbs are blown/mising, this will also trigger the fault light. That is confirmed here after searching previous threads:-

If you use the link I posted earlier www.topbuzz1.carenthusiasts.co.uk/info/abs_codes/a...m and find the diagnostic port, hopefully you\'ll be able to trace the fault and remedy it.
Write back and let us know how you got on.
