Looking for some troubleshooting help with the ant-skid system. During taxi after flight, below 15 knots, with anti-skid sytem on we have no nomal brakes, when anti-skid system switched off normal brakes work fine. We have already changed two control boxes, both control valves, all 4 transducers and normal brake selector valve, no joy. Anti-skid system works as advertised during system checks.
We are currently checking all wiring, but so far all seems good.
Any suggestions would be great.
