Using anti-seize or synthetic grease on brake caliper bore to prevent rust

[oly]

How many people do this?

My DE instructor, who is also a mechanic recommended it. Specifically, he puts copper anti-seize on the bore surface that is behind the dust seal and on the non pressure side of the o-ring. This seems like a very good idea because the dust seals don't survive very long in a track environment.

Also it seems like an even better idea would be to use nickel anti-seize or ceramic brake caliper synthetic grease instead. Permatext information:
copper anti-seize to 1800F
nickel anti-seize to 2400F
synthetic brake grease to 2800F

What does everybody think?

since its just on the non pressure side of the oring, and behind the dust seal, it couldn't hurt to do that.

As long as it's not on the wet side of the piston I don't think Therese any problem as long as this is a track car (brakes rebuilt every season). But for everyday drivers, not nessary.

The piston bores should be lubed w/ Unisilikon TK 44 N paste

the pad seating and pad sliding points should be lubed w/Optimoly HT which is a Cu based paste

the Permatex products noted are probably equivalent

Bill,

Does "The piston bores should be lubed w/ Unisilikon TK 44 N paste" mean behind the dust seal and on the non pressure side of the o-ring? Or the whole bore?

What is Unisilikon TK 44 N paste and where do you buy it?

And where do you buy Optimoly HT?

Yes, use Unisilikon anywhere under the outer seals and a dab of HT along the sliding edges of the pads.

Both are available through the Porsche parts systems but are considered hazardous materials. Some places won't ship them as a result.

Unisilikon is Porsche part # 000.043.117.00 for a 50 g tube
Optimoly HT is Porsche part # 000.043.004.00 for a 90 g tube


I have used Permatex for the Cu based high heat lube also Optimoly and Plastilube

PP sells plastilube; I used it last time and it was good times, man. Good times.

Okay, thanks for the posts everybody!
