Lubricating calipers

[johndownunder]

Hi all - I'mnow assembling my newly stripped and painted E38 rear calipers and a useful youtube diy video speaks of using a 'brake paste'. Is a normal antiseize product ok?

Its one and the same though some A/S compounds are for higher temps, like braking applications. Check your label. I have used regular A/S with no problem but it doesn't last forever.

Be sure to get it on the contact points where the shoes slide back and forth under braking. Don't get any on the rotor or pad. If you do, chase it with a shot of brake cleaner.

Don't forget to "season" your pads after install. Light braking at first. Let them cool. The next day medium braking with a good cooling off period of driving. Then, on the third day, firmer braking followed by a cooling down period. Never slam on the brakes to the max, or brake hard and then park the car -unless its to avoid an accident! Heating new pads up to max temp right away can cause the friction material to separate from the metal backing. Slow heating-cooling cycles help prevent that.

"Gute Fahrt!"

I use 3m silicone paste for the sliding parts

Silicone is high temp. No problems with it "running" during summer stop and go?

I bought a set of Aussie "carbon composite" pads for my fronts on the 528. They were harder and supposedly lest dusty. In summer, they would start squealing and I'd take 'em off and clean them good, lube them and re-assemble. A month later, they started squealing again under light pressure. The anti-sieze was everywhere I had brushed it on EXCEPT between the slidey parts. Never could figure out where that was going. And that was hi-temp brake lube...

Another one of life's mysteries....

What about ceramic brake caliper grease?

3m silicone stays in place

PB,

That must be ultra-high temp stuff! Out here in Phoenix, in the summer, you need that kind of lubricant. My 528 had it easy at 0315 in the morning zipping down the freeway but the legs home at peak heat in traffic during rush hour were brutal. Fortunately I usually only made one round trip a week. The rest of the time the car sat.

JC,

Good to hear. Thanks.

What about ceramic brake caliper grease?

I use Permatex ceramic paste, also be avised that contray to what people might say , the slide pins are brass, which is self-liubricating, no need for the grease.

Sil Glyde has been around for a while. I use to use it but have bedn using the Permatex Ceramic lately. I really dont know whether one is better than the other.

+1 I use Silglyde for my DD and Permatex Ceramic ( purple stuff) for my Track rats.

Yeah, just picked that tube up for the rebuild of the wifes "new" F100 brake system. New calipers and pistons. Freaking front calipers have more slide surface than an aicraft carrier elevator..... Caliper retention design is weird......
