  1. I flew with an old A-model captain when I was an FE with Transafrik in Angola. He enjoyed telling the story of departing somewhere in the very cold icy north. The funny thing is that he departed with the parking brake set and when he landed at Pope AFB (I think), he blew all 4 mains! Before you ask about the anti-skid light, I also asked that question. He said the early A-models had no anti-skid inoperative light. Some of you old heads may remember Bonzo Von Haven -- a legend in the Herc world. Don R.

  2. Assuming you performed fault isolation and normal operational checks, Check back pressure of brake system (should be under 70 PSI at each wheel, if one brake reads 10 psi or more higher, look farther) , check minimum brake pressure (should be over 1700 psi and max around 2030 and should be equal between left and right under same pedal pressure), check electrical grounds for anti-skid control valves (ensure they are tight and not corroded), check anti-skid control valve filters (if dirty, replace), check brakes for ability to return (watch pressure plate return after pressure release, should return equally), check tranducers for smooth operation and check voltage output with drill. If you find nothing, replace parts in this order. 1. anti-skid control box. 2. anti-skid control valve. 3. transducer Without being there and being able to look at it, this is about best I can offer. Tons of things that could cause this but most involve electrical signal between transducer/box/valve.
