There is a very good chance that your front rotors have become warped.
Two of my older Subarus had developed this syndrome, as heat
dissapation seems to be a problem for Soobs. If it turns out this is
the problem, I would recommend investing in a set of slotted/
cross-drilled rotors.
Does this sound reasonable to others?...Carl1luckytexan?
Yes, it does. I have also found bad tires to cause the same thing. The
difference is often whether or not the tires are getting 'old' (not so
much in wear - but in years too.) 'Warped' rotors are also likely to be
felt as a pulsation in the brake pedal. THAT is very likely to be warped
rotors. Since you have a '99, you tires can't really be 'old', so unless
you have tires that are getting worn, have never been rotated, etc.
,you probably need to have the rotors turned or replaced. In an effort
to keep unsprung weight to a minimun, nowadays rotors are somewhat less
'beefy' and if they have been turned before you may need new ones. Also,
some folks have reported that, severely heated/warped rotors are likely
to go bad again after being turned. I would probably opt for an entire
brake rebuild with new rotors. If you want a little higher performance,
get slotted rotors. Factory replacemnets will likely give you the
quietest and most durable combination of rotor/pads. After markets like
stoptech, brembo, Axxis, EBC ,etc. are good too - but may be noisy or
decrease rotor life and are more for 'track' or high performance
driving. Stoptech has some interesting reading on 'warped' rotors at
their website that corresponds to what another post mentioned about
applying the brakes and holding them following a hard stop.

Bottom line - most likely rotors - most likely the fronts.
