I recently cleaned and put new seal kits in the brakes on my SC. Read the DIY tutorial and watched the videos from the PMB website since that's what those guys do. Appears they are using a Permatex Ceramic Extreme grease on the pistons and seals. It's purple in appearance. I looked over the Permatex website and their TDS info and it appears their Silicone Ceramic Extreme grease is a newer product supposedly safe for all rubber components. It's orange in appearance. That's what I went with at the local FLAPS. Part no. 24129 about $5. Had plenty to do all the calipers with plenty left over even with a little 0.5 oz. tube.

My inner bores and pistons looked fine once getting them out. I had 3 calipers that were seizing up hence the reason to do the job. The pads upon inspection were on the last mm's of their life. It was very evident that the corrosion in the bores outboard of the seal in the caliper and under the dust boot was the culprit of my hanging brakes, along with the old flexible brake lines I also replaced. That being said, I used the grease in the bores and under the dust boots. I don't think just using brake fluid will do much outboard of the seal and under the dust boots....but initiate and enhance another round of corrosion. My brakes are wonderful now, and I've actually got a car that rolls even on the slightest incline.
