Brake caliper sliding pin grease

[Howard-]

I've searched the internets high and low and can't find a definitive answer... What type of grease should I use to lubricate the pins that the caliper slides on? (MX5 FWIW)

I know I need to use copper grease for the back of the pads and where they move on the carrier but what about the pins?

I always thought that you just gave them a good clean and NOT use grease in the sliders as dirt can mix with it and cause wear and sticking

[mcford]

I usually use a smear of copper grease. They are usually protected by rubber boots that will keep the dirt out, but not always the moisture, which will lead to corrosion and seizing up. Wear due to erosion by grit shouldn't really be a problem as their movement during operation is quite limited.

Arrgh! Copper grease is a bad choice as it is petroleum based and will soften and damage the boots on the caliper slides.

The correct grease is a silicone based one, and the only way I have managed to get hold if it is in small tubes as part of replacement slider pin kits.

You want red brake grease. Its a rubber compatiable grease.

can be quite difficult to get hold of over the counter ,i know i've tried recently !

I believe halfords sell it, failing that I also think your local Mitsubishi garage sells it, as Mitsi brakes have a tendency of being under specced for the cars and get very hot, so need the proper grease.

I've struggled in the past & then found various sellers on E bay of all things.

Had similar difficulty myself getting some. Opus oils sell it in nice big tubs I eventually found out.

lithium grease.
copper grease is the exact opposite of what you want!

Adding to an old thread - is Red Rubber grease still the best thing to use or are there better alternatives now? If so, does anyone know of any stockists I can pick up from instead of waiting several days from the net? (The squeaking is driving me berserk).

Red rubber grease is veggie based and will wash away easily so used for seal assembly.
Normal grease and lithium can react with 'rubber' components depending on the make up of the grease and rubber.
Silicone grease for sliding pins as water resistant and safe with rubber.
A 20g tube of Carlube silicone grease on ebay was £2.69 with postage.

An old post but hopefully someone will see it 😬 can I use silicone grease on the sliders, pad guides and piston

[SebringMan]

Yes, you can
