D2a Brake Failure

[LandyAndy]

Just met a couple of older Landy owners that are not happy campers.
They came down from Geraldton(spoke highly of their "local" landy mechanics Whyatts Automotive Geraldton) as their son was in hospital.
Their D2 got written off in the hailstorm the other week.
They bought a replacement D2a,nice looking vehicle.
Only picked it up tuesday,its brakes failed,no pedal at all.The caryard(Perth landy dealer) fixed the brakes,new master cylinder they think.It got them to Williams today but the brakes failed again.Front left and right rear locking on this time.All the dash lights were on.I was willing to have a tinker with nanocom but seen as it was a waranty job we agreed flat topping it back to the dealer was the best bet.
Any ideas what the issue may have been??? to release the brakes the local roadhouse owner had to let fluid go ad the ABS pump.

just out of curiosity Andy was that a vienna green number from a well known Landy dealer in Perth

It sounds as though there were 2 distinct faults. Pedal to the floor when the reservoir is full and no burst lines can really only be the master cylinder. The current one is bound to be modulator valves not closed, possibly due to rubbish from never having been bled properly in its life.
