SL/R231: Power Stop Carbon Ceramic Pads Installed




The new pads did include silicone lubricant. We reused the hardware so no additional parts were needed.
The Power Stop pads fit perfectly. I have only driven about 25 miles but so far, so good. No squealing or noises. I will update this post in terms of the amount of brake dust after I have driven a couple hundred miles.
Brake sensors were located on the right front and right rear wheels. I could have reused the sensors but since I had purchased new ones we did replace the sensors with new ones. I have 2 extra sensors if anyone needs them. $8 each including shipping. The same sensors are used on front and rear.
Will stay tuned for the dust reports as I also just cleaned my wheels of that nasty dust.

After a 250 mile road trip I would estimate the amount of brake dust on the wheels is reduced by about 60-75%. Also the dust that is present is lighter in color and thus not as obvious on the wheels. No brake noise at all and braking performance seems to be equal to the OEM pads.
First photo is the rear wheel. A little more dust on the front wheel. Overall, I am satisfied with the results.

Added: I now have over 1000 miles on the new pads. Dust has been reduced by at least 75%. No noise and no decline in braking performance on the street.

I had pretty much decided to go with the Porterfield R4-S pads before reading your post. I had replaced the pads on my Corvette with Akebono pads, but they do not seem available for our cars. After a few years, the Akebonos began to squeal after the car was parked for an hour or two, like when leaving a parking space, then stopped during regular driving. I assumed it was due to some accumulated brake dust.
