Brake Caliper Silicone Grease?

I just put new rotors and pads on my 2000 Tourer. The rotors have 99k mikes, 3rd +\- set of pads in 10 years. Wore the new pads down to the metal in 5 days ( about 900 miles ). Turns out my pins are sticking. Expensive lesson. :'( Never did anything to the brakes before exept pads and fluid change. Started doing that after the dealer couldn't do a proper R&R and screwed them up.
Anyway, I'm told I need silicone grease. Only I can't find any. I've been to three parts stores. I got some Permatex brake caliper lube but it seems a little thick and I'm afraid to use it. I've seen several posts refering to silicone grease. What are you guys using and where did you get it.
Also, if you have any other "you shoulds" aboult brakes or you would like to kick me for not rebuilding the calipers already, I'm bent over! :o

Silicone grease is also know as bulb grease or dielectric grease. I think you should use some steel wool to smooth the pins and forget the grease. Grease will catch and hold dirt.

or you can get sil-glide, but on car and truck calipers i always used thined never seize i would diloute it with wd-40 so it will spread thin

I always sand down the pins, just get them smooth and knock off the corrosion. Or put them on my bench wheel, when their bad replace them (cheaper than rotors) Then I grease them with the same grease I use on everything. Bel-Ray waterproof. I pull clean, inspect, grease these with every 10 thousand mile spline lube. This practice I've found will save you pads, froze calipers and rotors.
If you can't be a good example: be a WARNING!!

Permatex brake caliper lube is what I used on my caliper pins, it is perfect for that.



If you are rebuilding your calipers (ie - taking them apart, and replacing the seals), BEWARE: the
manual sez "coat the new piston seals and dust seals with silicone grease" - don't do that...
just coat them with brake fluid.

When I got my somewhat tired Red and White, I just changed the fluid and pads, and had trouble
with my brakes later... a full caliper rebuild, cleaning everything like brand new and changing out
the seals (I even changed out the rubber booties) is easy and results in good dependable brakes...

Thanks for the help Guys! :) I plan to roll my odometer this year if I can just keep it on the road for 800 more miles. After almost 10 years and 98K trouble free miles I've had a short riding season. Down 2 weeks for new clutch,  1 week for alternator, 3 months for broken ankle ( a cage driver supplied that  >:( ) and a week down for rear tire, shocks, front brakes and tune up. I'd sure like to ride the rest of the year out!

Thanks
