bad master cylinder on 90q20v?

[WAUFX at aol.com]

Hey all-

Well I finally got the cruise and coolant gauge working again....for good I
hope this time.

Now I want to tackle my warped rotors. The car came with badly warped rotors.
I replaced them (foolishly) with Bendix rotors which began to warp after 2k
miles.

Today, I jacked up each wheel individually and spun them. The rears spun
freely but the fronts seem to be stuck. They will spin, but not as freely as
the rears and I can hear the pads bearing down on the rotors. I recently
greased the guide pins to see if that was the problem. The car had new front
calipers at 141000 and it has 160000 miles on it now. I would think a sticky
master cylinder? I have a mostly complete set of records from 96000 on and
there is no mention of a master cylinder replacement anywhere...

But then again, wouldn't a bad master cause *all four* calipers to drag a
bit? Also, I'm not noticing any of what I know to be symptoms of a bad
master: smelling burning brakes, noticing hesitant acceleration due to
dragging brakes, or feeling hot rims during and after braking.

Any ideas?

Thanks...
