Orange grease?

[Calan]

In many areas of the FSM (especially brakes), Mitsu says to use the "repair kit orange grease". I have yet to see any of this stuff in any rebuild kit I've gotten. I've always used plain old caliper grease on brakes, and moly or axle grease for lower heat suspension components.

Just out of curisosity, what are you guys using as substitutes for the "orange grease"?

I use reybestos synthetic lube for the back of my pads;

Honda/Acura Synthetic Moly Lube Its that burgundy/Metallic Colored grease, I purchase from Wurth for my hardware.

As for my slide pins, I have had a lot of issues with the reybestos stuff gumming up, and the moly lube/napa synthetic black stuff, and a few others "caking". So I now use white lithium grease. It has been about a year since I switched to it for the slide pins, and have found no issues yet.

Just make sure your slide pin boots have no tears or they have not swelled; thus allowing dirt and ect. to enter into the pin/bore assembly.

I also use white lithium grease occasionally, but wasn't sure how it would stand up to caliper heat so I've never tried it there.

What do you use inside the calipers (like the rear emergency brake components under the piston)? I think caliper grease would be to tacky and would gum up the needle bearings that the pivot arm rides in. I think I used moly grease last time, but not sure what I want to try this time around.

I like white lithium grease for any rear drum or e brake drum application.

As for when I do brakes, I normally, sand the hub surface and rotor surface, spray on CU800 which is an anti rust/corrosion along with aids in absorbing brake noise.

Then I do as follows above; Reybestos for back of the pads, Wurth CU1100 for the caliper hardware.

I just spoke with my Wurth rep, he said they make 2 products one call true glide, and one called assembly paste that some of the other shops use for the slide pins, I guess its worth a shot.

However, that orange grease you are referring to that sometimes comes with factory boxed pads, use ment to be used for your slide lube, and the metallic colored grease, is for the hardware, is EXACTLY like the CU1100.

Have you ever torn into the rear calipers? The lever and self-adjuster that the emergency brake ties into rides in a needle roller bearing that sits at the back of the piston bore. The joint between the actuator and lever, as well as the needle bearings themselves are heavily lubed with grease. But...the whole thing is also exposed to brake fluid on the other side of an o-ring, and I'm sure there is some overlap between fluid and grease in that area of the bore.

I'm wondering if the factory grease is specifically formulated to be compatibile with the brake fluid environment. I would think that most types of grease and brake fluid wouldn't play nice together.

Not a big deal... I just got to thinking about it last night as I was wrestling with the caliper disassembly.
