I think all of us C3 owners know by now that C3 brakes are pretty horrible. Well, I got to find that out a couple of weeks ago when they failed on me. That's right... pedal went all the way to the floor! Fortunately, I was only around the corner from my house, and I did manage to come to a stop as the pedal hit the floor.
I spoke with one of C3VR's members, 4webers (George), about it and he immediately knew what I should do. He told me about a set of "O-Ring Caliper Pistons" he had put in his C3 and how the difference was like night and day. He said I should absolutely buy these and install them. Well, I'm taking his advice and I ordered a set yesterday. The manufacturing company is called Zero Tolerance Industries (or ZTI).
Here are some details about the pistons according to their website: Eliminates Air Pumping, Stops Leaking Brakes When Sitting, Eliminates Brake Squeaking, Superior Technical Design Reduces Pad Wear, Maximizes Braking Potential 25%-30%, Manufactured From 606IT6 Aluminum Billet, Aircraft O-Ring Technology, May Be Installed In Original or Stainless, Brake Calipers, No Special Tools or Machining Required for Installation, Made in U.S.A., Years of Successful Testing.
I spoke with the owner of the company, Mike when I placed the order and he definitely knows his stuff! It is recommended that you don't wait for your brakes to tell you they have a problem, like mine did. You should be proactive about it and buy these pistons now! I'm lucky I was so close to home, and didn't run into a tree!
Mike said he should be sending me out the set of pistons this week, so hopefully I'll get to install them within the next couple of weeks. I will keep you updated on the progress through posts on the C3VR Forums.
In the meantime, I recommend you check out their website, read-up on them and perhaps buy yourself a set. They are only $275 and that includes shipping and handling!
Click here to go to ZTI's website now. The site isn't 100% complete yet, and you have to place your order by phone, but the info on the pistons is there. If you do speak to Mike and/or place an order, please be sure to tell him that Adam from C3 Vette Registry sent you!
Here's a photo of the pistons from the website:
