i would like to ask, whether this type of rubber grease suitable to lubricate sliding pin on caliper brake? thank you

 

Not sure what rubber grease is, but for slider pins, you should be using brake grease designed for the pins.

 

Should be sillicone grease...

Kleen-Flo | Products - Eze Slide

 

 

If dielectric grease, this also can be use on sliding pin, am i right?

 

In the aviation business we use to use DOW 4 on caliper pins but they still got water into them and rusted. We switched to anti-seize and the rust problems went away because the anti-seize stuck to the pins rather that just lubricating them. We also use Dow 4 on oil filter gaskets. You do NOT want to use it on anything with an oxygen sensor like you Fit. Silicone is death to oxygen sensors. Do do NOT use Dow 4 on anything near the engine. Use on brakes components is fine.

 

Brakes get HOT especially in the summer.

So you need a grease that can withstand the temps. Not sure if the 400F in the dielectric grease is enough?



The easy answer is to go to your local autoparts store and ask for brake grease for slider pins. You can buy it in little blister packs or in a jar.

The synthetic varieties have the additional benefit of not deteriorating the protective rubber boots on the sliders.


PS: Rubber Grease is meant to lubricate the seals inside brake & clutch cylinders...

 

napa sells stuff called sil-glyde... sounds sexy, works great.

 

I use Dow Molykote 44 silicone grease on the Harley. I see the Fit service manual recommends it, too.

 

Molykote G-3407 specially formulated for sliding pins

 

Napa Syl-Glide works fine. I use the Kleen-Flo Eze-Slide personally.

Stay away from any Permatex brand grease. They make the rubbers swell.

 

This! I found that out the hard way. I ended up having to replace all the rubber bushings in my Harley. Nothing like having both brake calipers seize up at 60 MPH.

 

Yes, I have 2 massive tubes of that, I call it Duck Butter....lol

 

I believe that stuff is petroleum based, bad on rubber.
