is dielectric grease == silicon grease?

I went through autozone, advance auto parts, consumer auto parts, pepboys, home depot... to look for silicon grease, and none of the sale person know what the hell am I talking about, they keep giving me silicon adhesive or lithium (white) brake grease in which I didn't see any mention of silicon on the label.

The closet I can find in all stores is a small tub of silicon dielectric tune-up grease from 3M in which I been using for electrical contacts...

The question is, is this the silicon grease that Honda and Fred use in various component in the bike such as brake pin, brake & clutch levers...?

Good question. I always assumed they were about the same thing but I really don't know for sure. Hopefully someone can tell us the answer.

I've always used Dow DC-4

Just a tiny dab ... a tube like this will last the rest of your life

Silicone grease is readily available in the PLUMBING DEPT. of your local hardware store. Its most common use is to lubricate o-rings. It comes in tubes & tubs. Silicone spray is also available in the hardware store.

Auto parts stores may not carry these silicone products because their use in automotive applications is limited.

"Dielectric Tune-Up Grease is a silicone dielectric
compound whose dielectric and lubricitous properties facilitate
and improve tune-ups. The compound prevents voltage
leakage around any electrical connector thereby insuring a
strong spark in high energy automotive ignition systems. The
compound is also an excellent lubricant on rubber, plastic and
ceramic surfaces and it also has good high temperature
properties, thus preventing fusing of spark plug boots to the
spark plug. It will make installation of the boots easier."
So I guess you can call it whatever you want. It's still a silicone product and can be used for electrical connections as well as a high temp lubricant for rubber spark plug boots. I use it on all my electrical connections as well as lubricating the brake pad pins and caliper sliders.
It's a handy compound that should be in everyone's garage. I also use it on light bulb bases before installing them in my lamps. keeps them from corroding and sticking.

Quick thought is the "high temperture silicon grease", that is moucho deniaro $$$$$. Used in industry applications, yes a dab will do ya too. Guessing like few hundred a lb.

autozone di-electric grease
any scuba shop has the real deal used a lot in scuba diving, scuba 100% silicone is the best quality

Find a supplier who carries Raybestos Brake products.
Order the following: Raybestos Silicone Brake Lubricant, Part # DBL-2

Do not choke when you pay the bill.

Use sparingly.

I currently have 5 different brake lubes for various brake parts, the Raybestos grease is the best IMHO and works in the majority of applications.

Do not use dielectric ignition grease on brake parts or Brake lube on Ignition parts. Do not use plumbers grease. Do not use petroleum grease.

From the web site, www.brakeandfrontend.com I've pulled the following quote:
TYPES OF GREASE
For brake work, technicians actually need two different types of grease: one for lubricating the mechanical brake components, and another for lubricating seals and boots and other internal parts when assembling calipers and wheel cylinders. In other words, you need one type of lubricant for external mechanical components and another type for lubricating internal components.

There is a variety of brake lubricants available in the market today. To choose a lubricant that best suits your needs, you need to know something about the different types of products.

Synthetic-based boundary-type lubricants that come in a tube, paste or stick form have a high solids content and typically contain a variety of friction-reducing ingredients, such as molybdenum disulfide (moly or MOS2) and graphite. Moly and graphite are both "dry-film" lubricants that can handle high temperatures and pressures. Some of these products are rated to withstand intermittent temperatures as high as 2,400 degrees F! Moly and graphite have excellent staying power and won’t evaporate or burn off over time, and they won’t attract or hold dirt like "wet" lubricants can. This type of product is ideal for high-temperature applications where long-lasting metal-to-metal lubrication is essential for good brake performance.

Silicone-based brake grease is designed for caliper and wheel cylinder assembly work because silicone is an excellent lubricant for rubber and plastic. It is compatible with all rubber compounds including nitrile, Teflon, nylon and other synthetic rubbers. Silcone’s normal working range is -40 degrees F to 400 degrees F. But, it is a "wet" lubricant that can attract and hold dirt, making it less suited for lubricating external metal-to-metal contact points such as caliper mounts and shoe pads. This type of product is best suited for assembling calipers and wheel cylinders.

Another synthetic-based brake grease uses polyalphaolefin (PAO) as its main ingredient. PAO-based brake lubricants are also excellent for assembly work and lubricating seals and boots. PAO offers superior rust protection, making it well suited for brake systems operated in wet environments. PAO brake grease may also include various amounts of moly, graphite and Teflon to enhance its lubricating properties. This type of product can withstand intermittent temperatures of up to 600 degrees F, and can be used for both assembly and external lubrication.

White lithium is a low-temperature grease that can be used to lubricate drum brake hardware, but lacks the heat-resistance for front disc brakes.

Regardless of what type of brake lubricant you choose, always follow the supplier’s recommendations as to how their product should be used. And, always be careful not to get any grease on the brake linings.
