The old O ring bushings on my calipers are totally shot, they are sqished, cracked, and just plain wore out.

Getting new ones today, I don't want this to happen again, I think it's a big source of the hard pulling to the right when I brake.

What kind of lubricant should I use on the bushings to prevent this, I'd assume axle grease would eat away at the rubber, lithium grease doesn't seem like it'd be thick enough to stay on there.

Graphite lube? It might work, and I don't think it will damage the rubber bushings. Maybe someone else knows more about that.

 

Run down to your local parts store and grab some sythetic caliper grease. That should work fine and you can use it on the slides and mounting points too!

 

Theres a synthetic grease they sell in small tubes for just that purpose. Just about anything else will melt off and be useless in a short period of time.

 

Yep, silicone.. Pep Boys is selling little packets (like a Ketchup packet) of silicone brake part lube for $0.95. Previously, I was using a Silicone Dielectric SL-4 (forget the manufacturer, it's not Permatex) for the caliper stuff. I'm not sure if the dielectric is the same stuff, but hey, they're both made outta silicone!

i've used white greese in the past with good results.

Yeah, it kinda dawned on me while I was at the store to use the thick clear silicone dieletric ****

 

Try Permatex Ultra Disc Brake Caliper Lube, p/n 24110, which is a green synthetic grease.
Pretty expensive, ~$11 for a pint, relatively a new product so you may have to go to a major brands auto parts store.
I have no long term results since it is new.
My auto parts guy says all the professional garages are now using this. My guess, probably a step up from silicon grease.
