The ABS unit on a 92 Imperial is made by Bendix...my 90 had a very expensive Bosch unit and I learned a lot from the Allpar website concerning FWD ABS problems. Here's a link to ABS discussion-there's more info if you dig for it: http://www.allpar.com/fix/ABS.html You may be experiencing pump failure which isn't the end of the world with Bendix...rebuilt pumps are cheap and plentiful.
