I have a 93 silverado, brakes locked up when I was slowing down to turn, can't move it now. Lines all look good, any suggestions please?

Sounds like a possible proportioning valve has failed, or wheel cylinders/caliper. Jack it up one tire at a time and spin the tire. Make sure the trans is in neutral, It will identify which wheel/wheels are locked up, then get back to us.

No one added the wrong fluid to the master cylinder did they? You can tell by popping off the top of the resevoir and seeing if the rubber seal for the cap swells and pops off the cap as soon as you get the cap off.
