Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / October 2004Need source for grease compatible with brakes
The overhaul instructions for my hydraulic clutch slave cylinder call for using a grease that's compatible with brake fluid to pack the side of the piston exposed to the air, this grease sits on the surface that the seal rides over each time the clutch is activated. Autozone had no clue, all they had was sylglide for the pins and sliders and I know that's not compatible with brake fluid. So, what brand, model, part number, etc do I need to get?

I think it's called rubber lubricant. I have a tube of it somewhere but I can't put my hands on it right now. I'd look at Repco Brakes website or Tilton Engineering or Maybe even Girlings website.

I've just gotten into the habit of *not* rebuilding parts until I'm ready to install and then just dipping the seals in clean brake fluid. nate Signaturereplace "fly" with "com" to reply. http://home.comcast.net/~njnagel >The overhaul instructions for my hydraulic clutch slave >cylinder call for using a grease that's compatible with [quoted text clipped - 6 lines] > >JazzMan Do a search for HYDRAULIC ASSEMBLY FLUID. I have a bottle from Raybestos that I bought like 30 years ago. Still works but I no longer rebuild stuff. I NEVER see this kind of stuff in stores.

I called the Valvoline technical hotline today, and even they didn't know. The guy went and talked to one of their chemists and was told that there really wasn't such a thing, at least not that they knew about. I ny case the grease actually helps keep air out of the slave cylinder and keeps the bore from pitting. The way this slave works is that the piston travels back and forth over a surface such that it is alternately exposed to brake fluid and to air. I've pretty much decided that what I'm going to do is to convert my clutch over to DOT5 silicone and use a commonly available silicone grease. Solves that problem.

Silicone grease is compatible with regular brake fluid. You don't need to convert to DOT5.

I did a search on "Raybestos BAF 12" and got 11 hits with only ONE being the one needed and dated as recently in the post as 2002. So I am assuming Raybestos still makes this stuff. I would say the BAF above stands for Brake Assembly Fluid. ||>> Do a search for HYDRAULIC ASSEMBLY FLUID. ||>> [quoted text clipped - 9 lines] || ||So I am assuming Raybestos still makes this stuff. Yep. We have a 2-year supply here. ||I would say the BAF above stands for Brake Assembly Fluid. That would be correct.

It's just silicone dielectric grease. Here's an example: http://www.themoldersedge.com/polish.htm another: http://www.mgchemicals.com/products/8462.html Googling for silicone dielectric grease turns up many more. When you rebuild your calipers, applying this stuff to the seals and piston makes for a really nice job.
