Default FS--Stainless Steel brake pucks

I purchased these to install about a year ago, but ended up buying a Wilwood front brake set-up. I do not know the manufacturer of them, but as you can see, there is some great machining done to them.

This is the set that Doug Rippie sells at $140.


This is the ones that I have:


The Machining around the top should do a better job of keeping the heat from from getting to the pads.

I'd like to get $150 for the set of 4 pucks. I'll ups them. No pay pal.

Those aren't SS, those are Titanium! In addition they are 2 piece for even better heat isolation and correct thermal expansion. They are the cat's meow for anyone who has the stock calipers.

my buddy and I were debating the effectiveness of those a while ago.

The heat is created in the pads / rotor, (correct??, yes)
The object is to dissipate the heat out of the pads & rotor. (correct?, yes).
I like answering my own questions so far.

Certainly some heat is transfered to the caliper / pistons, and brake fluid in the caliper. I believe that is a good thing, as long as your not boiling the brake fluid. Otherwise where is all the heat going to go ??

Now we start introducing vented caliper pistons, titaium backing plates, which effectively locks the heat in the pad & rotor. Now your more prone to brake fade, and rotor damage.

so in my opinion, it's ok to have the heat sinking into the caliper, and fluid, and pistons, as long as your brake fluid is capable of handling the heat. get that heat out of the pads!! disipate it as much as possible, anywhere and everywhere.

all in my opinion of course

A couple incorrect assumptions here.

The most glaring one is that it is ok for your brake fluid to get hot. The MOST COMMON braking problem at HPDEs is a soft pedal (or even worse) caused by boiling your brake fluid. Anything you can do to keep heat out of your brake fluid is a good thing.

I use Motul RBF600 which has a dry boiling point of 597 degrees F, I have brake ducts blowing directly into the center of my rotors, and I still need to pump my brakes a little near the end of a track weekend.

These pistons would surely improve my brakes.

please re-read my post.
I never said it's ok to boil your brake fluid. obviously then your pedal goes to the floor.

certainly good and fresh fluid can withstand heat.

Yes, but even the best brake fluids have trouble dealing with the heat caused by racing. So it's best to keep the heat away from the brake fluid.

This is a great discussion on heat and how to keep it out of the brake fluid, but back to my original post: Does any one want to buy them?

all in my opinion of course
From the Wilwood catalog:Piston material is selected based on the caliper's intended operating environment. Stainless steel pistons are used most often in calipers intended for high performance or competition applications. Stainless steel is selected for its low heat transfer properties and high resistance to corrosion. For extreme temperature environments, Wilwood's exclusive multi-piece insulated Thermlock® pistons provide ultimate protection against heat transfer from the brake pads into the caliper body, piston seals, and brake fluid. Aluminum pistons are only used in low to medium temperature applications, usually in conjunction with rubber piston boots that protect the pistons from corrosion and debris.

Be sure to call them, I am sure they need some engineering advice.

A very stupid question: are these for a C4, C5, or C6?

Install them using only brake fluid for lubrication. Do not use anything else, and everything should be super clean.

The square face seal is in the caliper bore.

Ahh ok. Ive yet to take my calipers apart so I didnt know the seal was in the caliper bore. Shows how much I know...

They look like trick pistons. I would goto something like this if I didnt already decide to goto the Wilwood setup.
