Front brake rebuild question

I've cleaned up the brake calipers and pistons. I have a couple questions I'm hoping someone here can help me. Do the boots 49006 and 49006a have grease in them. It seems the 43044HOLDER-COMP-CALIPER had grease on it. What type of grease? Also I put them in is the 43049RING,PISTON SEAL higher on one side? I'll find out when i put it in I just thought I would get a heads up. If you have any cheats or advice I'd appreciate it.

The manual says: "Apply a thin coat of silicone grease to the caliper holder shafts and holder holes. (silicone grease is a special high temperature, water-resistant grease)"

So greasing the shaft would end up with grease on the boots, but you don't need to grease the boots themselves. A light coat, so it doesn't squish out/and or collect dirt.

Isn't there a groove in the piston for this seal to fit into? If so, it should be the same all around the piston. I may not understand the question.

Yes there's a groove. I was watching a caliper rebuild vid and I saw the ring seal that fits in the groove is higher on one side (inside or outside not sure). Thanks for the info from the manual. I need to get one of those soon. Thanks for all your help!

I should look at the video, kinda unsure about the ring sitting higher. The piston I looked at appeared to just have a straight groove around it. Could the ring have not been fully seated yet?

Get the download manual here on the site if you're on a pc and not a phone. Freebie!
