What grease for brake caliper guide bolts???

[Gly]

as per title, what greese do i need to use for this...

did the rear brake pads today...
and found that the greese on the rear right brake is completely dried up
and not letting the caliper move very well..

and wore down the pad on a funny angle...

according to Kieran's guide this is some special stuff...

anyone know what it is???

I've used a copper based grease without any ill effects.

It use to be called Copper Slip

The debate rages over copper slip. Some argue that it can shrink rubbers. It's certainly not the grease that Mitsubishi specify, but several members (including myself on Isaac's GLS) have used it with no ill effects.

The 'correct' grease appears to be a silicone-based one - doesn't attack rubber components, but I can't find anyone manufacturing/selling the recommended stuff. It looks not unlike red rubber grease, but it can't be that?!

Didn't you just know that we have it. I'll check in the morning but am pretty sure its the Series2000 Amsoil grease. Personally I thought copper slip worked OK.

Goodness me! Amsoil having a special super-dooper grease for the job! Who'd have thought it!!

/Do check.... This Thursday is payday and so I'll be ordering the final parts to do my brake overhaul.

...or you could look into the world of mountain biking for high grade lithium grease - used this on my old GLS to solve all manner of funny noises from front brakes with no ill effects....
it was even red too!!!

That's interesting..... Wonder if the Mitsubishi OEM grease is Lithium based then? Don? What say you? Is lithium grease used on slide and pivot pins?

I'm going to have to look this one up, I know that the guy who does servicing next door to my warehouse swears by copperslip but then again he puts copperslip on everything. The coloured greases are generally special and expensive. I would have thought from the problems the pins will encounter that the most applicable would have been our water resistant grease as its the sticking through corrsion thats the usual problem. The water resistant grease besides being fairly cheap is usually used for bearings and brakes on boat trailers that are reversed into the sea! If the bearings and brakes can survive this then I'm confident that it will stop corrosion and sticking on a road car. But I do welcome your comments.

Gly bro, I have some German stuff that Audi allows on the RS6 and the new RS4, want me to send u a tube of it??

[Gly]

yeh that would be sweet... ill send you a pm with my addy

[amsoil]

Having asked I'm told that the best stuff to use would be Copperslip, the real stuff not Comma or someone elses version.

While on the subject.. Does anyone know if we can just purchase the Rubber bits for the ends of the guide pins or do we have to order a complete New braking System including Discs, Pads, Brake Pipes, Master and Slave Cylinder, Brake Booster, ABS System etc..

[I-S]

See my other post for background...

Where did we get to on this? I've just done a bit of searching, and looks like lithium-based greases can handle up to about 250C (around the same as the boiling point of brake fluid). Is this enough for brake pin usage? Copaslip will go up to about 1100C (think at this point you might have a whole other heap of problems).

g6acb - So far the best grease I've found for mtb use is Amsoil GHD.

We need an Amsoil smiley.

Cheers for the info - may just tag some on to my next order


Made a smiley just for you Isaac

What do you ride g6acb? I've recently come up with a lovely concoction for fox float rear shocks, which consists of a mixture of Amsoil GHD and Amsoil ATF. Makes the consistency wetter than the plain grease, which is perfect for the air sleeve of the fox. GHD by itself is great in headsets and bearings. I'm just waiting for amsoil to come out with a 15wt fork oil (but I might brew my own out of 10wt and ATF)

Gah, double post...

[g6acb]

Cannondale f800sl - no rear shock here and front 'headshok' full of floaty light air (when it decides to keep it in ithat is)

its racked up 2500 miles in 3 years all off road and is starting to show its age a bit and require more and more tlc ...... been looking at an Orange 5 Pro - getting very tempted

Follow up on this one... as you may have read, this weekend I was mostly removing my calipers and I decided to check the condition of the pins, especially the fronts, which had previously stuck.

Based on what I found, I will *not* be using copaslip on my guide and locking pins again!

There's more to this story, which I will post when I get back from work.
