RE: [T3] Brake wierdness (stumped)

With *no* fluid loss, it's a mystery to me.  I'd still be inclined to check
the MC.  Sometimes fluid can sneak by the piston and the pedal does weird
things.

Also, check the hoses for swelling/weakness (if *that* doesn't scare you,
nothing will).

	Hi All-

	My brakes (68 square) are acting up in a strange way and I am hoping
	someone can help me diagnose the problem. Here's the deal -

	Today while on the freeway in heavy traffic I had to make a few
quick
	stops. I noticed a pull to the right side and immediately thought
that was
	strange. Soon after that the pedal started to feel a bit mushy, and
then it
	almost went to the floor! Because I have new replacement front
calipers,
	excellent condition discs, new rear cylinders/shoes etc.(and all
*clean*
	back there) and 6 month old 100% replaced brake fluid that was bled
right
	(I did all the work myself and the brakes have been *excellent* for
the
	last 6 months) I expected to find my master cylinder leaking like a
sieve,
	as it is the only part (besides the metal fluid tubing) that wasn't
	recently replaced.

	I got out of the car and checked the fluid level first....it was
full!
	Then I got under the front to look for the master cyl drip I was
	expecting.... Bone dry!  Then I went around to each wheel to see if
I had
	sprung a leak somewhere in the lines or at the rear cylinders. No
leaks! SO
	then I got back in t5.Snd started to nurse it home slowly, as I
was
	obviously paranoid about rearending/killing somebody. At first the
pedal
	felt strange and mushy, then, after I used the brakes a few more
times,
	started to feel normal again!  I did a few quick stops in an empty
parking
	lot to check them out and everything seems to be fine now.

	My problem is that I can't deal with unreliable brakes! Even though
they
	are working fine now I don't feel like driving it to work on the
freeway
	until I figure out what the problem is/was.  Any clues or things I
didn't
	think of/check?  TIA!!!
