Oil pressure gauge problem

My 93 Bronco's oil pressure gauge has started going to zero when I apply the brakes, like at a stop light, then returning to normal indication while driving. Can't figure this one out. Any help would be appreciated.

Get a good set of mechanical oil pressure and water temp gauges and leave the original ones disconnected. Then you will know what is heppening. Motorcraft oil filter may help also.

Check behind the dash the pedal might be yanking on a wire.

Does it only do it when the truck is up too temp? I had the same problem and the motor oil thinning out after warming up and bad main bearings did the same thing. Put a mechanical guage on there like b4 stated and go from there.
