benzjag,
I'd suggest 2 things:
- Check your accumulator is successfully charging from rest.
Open the bonnet and get someone to stand by the abs pump. Turn off ignition. Fully discharge the accumulator by pressing the brake pedal 20+ times. The pedal will become increasingly hard.
Leave your foot off the brake, turn on the ignition, count how long the abs pump runs for before cutting out. Are both the brake and abs light going out?
- Perform the blink test routine to identify what abs fault codes are being retained in the system
Good luck
Paul

The red Brake light is for the brake fluid reservoir level. If it was an ABS fault, the yellow Antilock light would come on. The sensor for the fluid level is built into the reservoir for the Teves IV system, and cannot be separately replaced. You have to replace the entire reservoir, but, of course, they are no longer available.
My reservoir level sensor failed on my 1995.25 V12 6.0, and the light was on all the time. I bought one of these:

Of course, it works backwards from the stock sensor. The stock sensor is closed when the reservoir is full. This cap contacts are open when the reservoir is full. So I rigged up a relay so that the contacts are closed except when energized by the new cap. It works fine.
Before you go thru all of that, clean the contacts on the connector near the reservoir. Just trace the wires leading out of the bottom of the reservoir.

Jon,
Your link did not show the cap you used. If the plugin wires at the bottom of the reservior were connected, would this turn off the light?
