The brakes were properly bled many months ago when replacing the brake fluid resevoir - like 10,000 miles ago.

So not sure the brake bleed is the solution, but I am still / forever a student here.

After turning the engine off and restarting, the lite was out and functioned normally with the handbrake etc.

Again, I often have the 3 amigos along - is this a progression of the abs module / shuttle valves going bad to worse...?

For the red brake warning coming on alone intermittently the most common is the handbrake switch but it can be the fluid sensor too, to rule them out unplug them one at a time and if it stops you know which one is making tricks... if no joy then it can become complicated, as long as this warning is alone it has nothing to do with ABS system only when it comes together with the 3 amigos

The red Brake light has reappeared. It is intermittently on (solid, not flashing) and intermittently off.

The manual indicates 3 possible reasons:
"A red brake graphic (all except NAS vehicles) or red BRAKE legend (NAS vehicles), to warn of low brake fluid
level, handbrake on and brake control system failure affecting EBD (electronic brake pressure distribution)."

Does this, along with the frequent (but not constant) appearance of the 3 amigos, suggest a bad ABS module?

No leaky calipers.

I will test the light using:

the most common is the handbrake switch but it can be the fluid sensor too, to rule them out unplug them one at a time and if it stops you know which one is making tricks..
But...
Where is the connection from the handbrake to light up the BRAKE light on the instrument cluster to unplug?

Thanks.

Info from EL.
Handbrake and low brake fluid level warning lamp
The handbrake and low brake fluid level warning lamps are connected to the instrument
pack from pin C0230-10 on a KO wire to Header C0293 LHD/C0285 RHD. From header
CO293 LHD/C0285 RHD a KO wire is connected to the handbrake switch, the handbrake
switch is locally earthed.
A second connection from header C0293 LHD/C0285 RHD is connected to the brake fluid
level switch on a KO wire. The brake fluid level switch is earthed on a B wire.
If either of the switches closes, an earth circuit via the closed switch contacts is completed
and the handbrake/low fluid level warning lamp will be illuminated. Power for the warning
lamp is internally connected to a supply from pin C0230-19. Pin C0239-19 is supplied power
from the ignition feed from fuse 27 in the passenger compartment fusebox.

For the handbrake switch you have to remove the central console and it's there near the lever
