Hey
I have KVR pads and drilled rotors and SS lines.
When i push the peddle down at a normal speed it seems a little mushie however if i push it down release it then push it down again it firms right up.
Is this normal?

Maybe you need to bleed the brakes? Air in the lines?

haha Ok
the scary thing is that no one has touched my breaks in like 2 years! That means I have been driving with air in the lines for that long?
When I jump on the breaks fast they seem solid.
How much pedle travel is normal?
What is involved in bleading them?

If you haven't touched the brakes for 2 years then you probably need to not only bleed your brakes, but bleed out the old and put new in. Old brake fluid absorbs water making the brakes less responsive. I'd say this is something you can try that will most likely make a difference and the cost is fairly minimal.

thats a good idea, use synthetic fluid for your brakes and youll experience less fade too. Synth brake fluid is definitely worth it and you can mix it with your old fluid with no problems. I just bled the brakes and replaced the bled out fluid with synthetic and I got a lot less fade.

You have a good fluid in there. A good fluid with a higher boiling point will resist picking up moisture better then a low quality fluid but it will still pick up moisture eventually. Volvo recommends replacement of brake fluid after 2 yrs/20,000 miles. So if you're going by the book it should be changed I guess. My mechanic who is excellent charges anywhere from $60-80 for a flush depending on what type of fluid you choose.

The only other possible could be the master cylinder, but I agree with the others, I would bleed out and change the fluid first. Easy DIY job

possible leaky wheel cylinders or master starting to go if not low on fluid maybe time for fullbrake inspection.

Full inspection is not a bad idea...

I have the same problem with Blue ATE and steel lines. I just wonder if the booster goes bad on an 850?

My 850 Turbo brakes have been acting funny too. Just recently when I press the brake pedal the first time it travel futher than when I release and press again. When I press it the second time, it seems to be higher. What to doooooooo?

Yea
Perfect description of the problem.
Now I havent done any tests ...but it seems to be stopping fine.
Any conclusive solutions? I dont want to have them blead only to realize it was a waste of $$.
