Greasing Caliper Slider Pins - what's the best way?

[Guido]

Is there any easy way to grease slider pins? Mine are covered with a tight fitting thick rubber boot that I'm afraid of tearing if I pull it back too much to access the pin.

Also I'm afraid I'd never get a good seal again once I'm done.

What if I use some type of syringe to inject the grease inside there?

How do you do it?

Thanks Martyn for the detailed reply - it was very informative and I will keep it for reference when I need to rebuild the caliper. Right now I'm just looking for an easy/safe way to grease the slider pins that allow the caliper to move slightly when the brakes are applied. Every time I take my wheels off (twice a year) I'd like to lube these because they seized on my previous car.
I'm wondering if prying back the rubber will damage them and if the caliper has to be removed. This is for preventive maintenance, not as a repair.

The dealership charges $70 for this which makes me think they don't remove the calipers.

Most of the boots fit like a tounge groove board, take an old tooth brush, clean around there real good you should see it, remove boot and lube away, I suggest copper never sieze, if the boot does not come off remove holder assembly and work from the oppisite side. Hope this helps.
