ABS /D.SC. Lights on

1. ANY HELP WOULD BE APPRECIATED! my 03 limited V8 4 runner
   is down right now due to what appears to be an ABS braking problem.
   
   a lexus mechanic used a scan tool the codes come back to the Brake actuator and accumulator pump ( cant drive as the brake pedal is rock hard )
   
   has anyone fixed this problem ??
   
   what was the cause?
   
   I'm told a new complete unit with Master cylinder and acc/pump is around 2700.00
   
   a new accum. pump alone is 1600.
   
   and a used from ebay between 500-700
