I spent yesterday with some PCA members on a wonderful drive. Check out the pics.

Update on the Porsche brakes. THEY ARE FREAK'N AMAZING! I didn't realize how bad they were...what a difference.

A couple of things prior to this work raised red flags. First, is when I needed (wanted) to stop the car in a hurry one of tires (or two...no sure) would lock up. I new this characteristic wasn't efficient or safe, but I wasn't sure why it was happening at the time. The next red flag was more of a "possibility" of why one or more of my tires would lock up when braking hard and it was the brake dust...I'll explain. My rear brakes would develop a much heavier brake dust coating on the rear wheels than my front brakes would on the front wheels. This characteristic concerned me because it told me there where either two different pad compounds front to rear and/or my rear brakes were doing the majority of the stopping...which we no isn't good. Either way, it called for an investigation.

Yes, there were two different brake pads front to rear (don't know the brands), and yes there was a obvious visual problem with my front calipers. After rebuilding the front calipers, installing all new pads of the same brands and bleeding the system the car is a completely different car.

The new characteristic are; first, the brake pedal travel actually increased. Before, I couldn't rev-match during my deccel and braking because when I pushed on the brake peddle, it would only move an inch or two thus not allowing me to roll my foot over to "blip" the throttle. Now that the travel has increase, the total height of the pedal during hard braking is much closer to the height of the throttle thus allowing me to roll my foot over and "blip" the throttle.

And second, is the overall braking ability. I can push the pedal as hard as I want and there is no more lock up of a tire...the harder I push, the harder it stops...AMAZING, pulls the eyeballs out of the sockets!

As far as the installation of the pistons, I believe I did them correctly. I made the the tool from some aluminum sheet metal using some math to come up with the "20 degrees" needed to set the piston. My math isn't as fresh as it used to be, but that's what the internet is for...right? Either way, no brake noise.
