[s-cars] ABS fuse pulled- Brake bias/proportion gone?

I'll third the opinion that this sounds like a sensor backed out a little bit.

ABS OFF switch went away after 92.  My 93 did not have one.

The 1995.5 switch to the EDL also meant a switch to later ABS which
took care of the proportioning using the ABS valves. ( aka EBD
(electronic brake distribution) or DRP (dynamic rear proportioning) ).

Until the 95.5 w/ EDL, the rear proportioning was still being done by
the load sensitive prop valve somewhere near the rear suspension -
this bit is prone to sticking.

Technically with a 93 you should be ok without ABS, as long as your
rear prop valve is in proper working order.
