Brake Grease argument throughout the world.

[Rust_Belt_Pete]

I know we go back and forth here about grease for caliper pins and rubber safe grease. I was watching russian speaking youtube automotive videos and they have a very similar argument. Apparently they are stuck on temperature resistance thinking that its the main issue with brake caliper grease.
I have watched many (mis)use the red toyota assembly grease for caliper pins or just outright use oil based products that swell the rubber bushings and seals. But many think that temperature resistance is why the grease fails and causes issues?

I know I have zero issues with the silicon grease I use. That has excellent oxidation resistance of course, as well as being hydrophobic and as good as it gets in regards to seal swell.

The factory grease does break down, often very quickly, and does swell seals.

So apparently the Mitsubishi RM grease is almost universal among Asian manufacturers and is also somewhat popular to be used for caliper pins in eastern Europe. They also mistaken use the red RX grease for caliper pins.

Lancer's service manual recommends NIGLUBE RX - 2 for the caliper pins and the pistons. An equivalent would be Seiken Rubber Grease.

I can see why, the packets included in rebuild kits have paper inserts only in japanese.

I have no luck with it anyway.

My Hyundai Accent does not seem to be affected by petroleum grease. I use a copper antiseize/corrosion inhibitor with a oil base. My Fords were not the case. The Gen Coupe has no sliders.

Do your caliper slide pins have rubber bushings?

Yes they do though it's not rubber. Top pins have a dual bushing. Same with the boots, it 'feels' like silicone but I don't know.

I use ACD silicone grease after lots of research.

I just slap a big ole glob of brake grease on the rotor and send it.

After many years of trial and error using just about every brake lube available - even the expensive ceramic ones - I have settled on this lube that works great, does not hurt rubber parts, lasts a long time and is cost effective. I have the fortune of seeing cars I service many times so I know what lube on what cars were used and when I saw many brands clump up and basically become worthless I stopped using them. This CRC brake lube has never come back bad- even after a year or more not looking just like I sent it. The lube stays working and is hi temp.

I've heard of Toyotas using siliconized rubber boots (FKM if I remember correctly). In this case, silicone grease would actually cause swelling.

BMW FSM says to use no grease at all, likely to reduce risk?

Hyundai says AI-11P grease what ever that is.

I can understand a new brake grease topic for a new to the market product, or a new type of rubber used on new vehicles. Otherwise it just creates a mess of redundant topics, when you can search for one of those and participate in it.

I just wanted to share how people look at brake grease on the other side of the world and what their priorities are. For example it appears that over in eastern Europe many people mistakenly use graphite lube for caliper pins.

I am curious have you used the orange stuff (niglube rm)? CRC silaramic?
You are in Texas so I am assuming your biggest killer of caliper pin grease is heat?
Over here in Buffalo NY if you pull a caliper pin you will likely find moisture corrosion and grease ruined by moisture.
Wondering if what works well for Texas weather is terrible for Buffalo NY lake effect rust belt central.

Yes that was one of the one's I tried and in turned into clumps. I believe there was a purple type and an orange type I tried that was made by permatex that "failed" in my opinion. I did like their green formula but it was unsafe for rubber.

UPDATE - misread your post, you said CRC brand - I have not tried that one. I will go look for it!

I am originally from Maryland and my memory agrees with what you said about the moisture and corrosion. I used good old Sil-glyde back then.
