P38A ABS Pump and Accumulator Diagnostics

Hi, I´ve recently bought a P38 Range Rover and the latest issue (of many already!) that I have experienced is somehow related to the braking system.
Both ABS and emergency brake lights come on at every first push of the brake pedal meanwhile I can hear the pump running.

Looking at this page
http://www.rangerovers.net/repairdetails/braketc/abs.html
I guess that the problem lays either on the accumulator or... somewhere else!

I followed the instruction for the diagnosys and the pump did cycle on repeatedly during the 5-minute wait, now what is "unclear" to me is the "some sort of internal leakage (probably a seal, or check-valve)".
I would change the accumulator but I feel that may not cure the issue.
Which "seal" or "check-valve" should I check?
Should I better change the accumulator and its electric pump or the whole ABS/master cylinder box?

The ABS light should be on but go out when you go over 5mph.

Bloody advert is stopping me from typing!

If the pump is running with every push of the pedal I would flush the brakes following the procedure in RAVE to the letter. Diagnostics might help. Failing that replace the accumulator as it is quick and fairly cheap. The pump is the hardest and most expensive option.

LOL

If the pump runs on every brake application the accumulator is knackered.
