Al,
You haven't mentioned the details of the car. It's not in your signature but I assume from your username that this is a 1995 XJS? If so, I'm also assuming that if it's what the US call a "1995 XJS" that it will then have the Teves ABS Brake system.
You mention that the car has new brakes and the fluid was flushed. Depending who did the work, this could be the cause of the problem.
There are wear issues with the Teves system that have only come to light in the last few years. For example if (like most workshops) they just push back the pistons when removing the pads without opening the bleed nipples first, you can dislodge sediment in the ABS valve block with potentially disastrous consequences. By the same token, if they don't know to bleed the low pressure side of the system when changing the fluid, before bleeding the wheel circuits, that's another issue. Or if they don't know how to bleed the rear wheel circuits properly, which is not as per a conventional brake system, that's yet another problem.
I would suggest you start with both the "blink" test of the Teves system to identify any faults thrown in the system. Then run through the defined 32 electrical tests and verify the integrity of the system. And see where that leaves you.
Good luck
Paul

Which Teves Systems Are There?
