05 T5 with 190k miles.
When brake pedal is touched brakes lock up and the car stops. If I try giving the gas it just starts brake torquing. If I let of rest for a min or Restart it goes normal unroll brake is touched and than it locks up. No warning lights illuminated. Any ideas?

Maybe , I thought maybe a bad hydraulic block?

I'd hope for a vacuum assist valve issue on the brake booster, it would be a lot cheaper than replacing the BCM/ABS-hydraulic unit. But it could be either one. Does it happen when the car is stationary? How about with the key on but engine not running? Last but not least, is the assist pump running (the little silver cylinder in front of the battery)?
