Why risk it anyway? You'll need to change your fluid every time you track the car. Bleeding some fluid during the pads swap is only good.

changing out fluid everytime you track the car may be a little excessive. i'm on the same fluid that i have been for a year (about 9 track days?) and will be changing it soon.
DOT 4 tends to absorb more water from the atmosphere, so it is best to change it out sooner than normal DOT 3, but every track day is excessive imho.

I've never heard of the contaminated fluid thing, but I usually do change my fluid before an event.
Opening a bleeder valve to change pads sounds a little messy, I barely have to move the pistons to swap pads. Then I hook up my bleeder bottle and have someone work the pedal and I'm done.

Just open on of the bleed valve (install your bleed tube) and "twist" the rotor against the pads. This will loosen the pads enough for removal.
Then it's just a matter of using an old pad or simply your thumbs to push the pistons back. With the bleed valve open, they won't offer much resistance.
Do not push the pistons back in without opening the bleed valves. A fluid reservoir overflow is the least of your problem. Think contaminated fluid being pushed back into the ABS module... Not good.

That is exactly what I do. It's quick and painless.

Between my 2000 Cobra R track car and my SSC Mazda3 I think I've changed front pads at least 25 times and I never have bled the brakes after a pad change..
And with the Brembo's on the 350 pad changes are very easy, I played with 3 different compounds at BeaveRun and was amazed at how fast I can get it done. I just push the pistons back and install the pads. No bleeding here......
I change brake fluid 1 time per season, not after every race. Might have something to do with the Motul racing brake fluid.
Now if I could only get the pads not to kick back............

I usually do about 3 pumps of fluid from each caliper after every track event, just to get the fluid that has been cooked the most out of the system.

I bought this to push the pistons back in my Brembo's. Soooo much cheaper than that $300 piston reset tool posted above.

You're all wusses! ![Big Grin](https://my350z.com/forum/images/smilies/biggrin.gif)
I've been changing the pads on my Z for five and a half years (and similarly on a 944 Turbo for two years before that) without special tools or bleeding or anything. The only tool I need for changing pads is a pair of needle-nose pliers to remove the clips and pins.
Slide out one of the old pads (leave the other one in place!), turn it 90 degrees and put it half-way back in, centered between the pistons, so that it's in contact with both. Then use it as a lever to push them back. It sometimes takes a little effort, but it's not too hard. When the pistons are all the way in, slide the new pad in.
Repeat the process with the other pad on that caliper, then go to the other corners.
You should check the level in the reservoir to make sure it doesn't overflow. I use an eyedropper to suck a little fluid out if it gets near the top.

Check out www.m-workz.net if you need OEM Brembo replacement pads. They have tons and are selling them for SUPER CHEAP.

I'm with you commasense. All this fuss about moving caliper pistons a few mm back in
If you apply pressure evenly on the piston you can use anything as a suitable lever. I use the old pads, but even a tire iron or big screwdriver works just as well . Just wrap them in a rag to avoid scratching the rotors or damaging the dust seals, try and make sure you are pushing on both sides of the piston and be gentle.

I never did it before on this car. On my Audi you needed a special tool as the piston screwed in. Now that I took my pads out I see how easy it is. However I still don't mind I bought the tool. It works well and was only $40. The tool also assures the piston goes back in perfectly even to avoid scrastching the piston bore.
