Bill,
I replaced the rear brakes and rotated drums a few thousand miles ago, but I
can see how not having the rear brakes properly adjusted could cause the
front brakes to "pump up" without the rear brakes offering enough resistance
to make the calipers back off. I will check that first. Do you manually
adjust the rear brakes or use the method of "backup and brake" to do an
automatic adjustment of the rear brakes? I was going to get a master
cylinder today, but I am glad to hear the proportioning valve should not
fail, there is little to it to fail anyway.
When I did replace my rear brakes, I found that the original shoes in there
had practically no wear anyway.
I appreciate the advice.

Rick, you may wanna check the rear brakes for proper adjsutment as well. I
had this same problem on my '95 and don't relly know what cured it. I too
replaced the front lines, the calipers etc. I also replaced the rear wheel
cylinders and the shoes and all the internal hardware about 2 years ago. I
also went the route of the proprtioning valve, supposedly it doesnt go bad.
If you go looking for one, it's a dealer only item... So off to the junkyard
I headed. Found out that the part number ona 98 is the same as on a 95, so
I swapped it in($25 from junkyard off a wrecked 98 with 25k on it) versus
$80 and a long backorder wait at stealership.
So before you go that route do a good rotor/drum turn if possible install
and adjust rear shooes good and do a complete brake fluid bleed.
HTH,
