I just replaced the rear brakes in my wifes 2003 G35 sedan. I took both sides apart and sent the rotors out to be turned. When I was putting the caliper back on I noticed the guidepins are different. Does anyone know if the caliper guide pin with the roller on it goes on top or bottom or does it matter?

 

I have the same question. Does anyone know?

 

According to my 06 service manual, the bushing goes on the top "sliding pin bolt". Is that what you were asking? Usually when I do brakes, I loosen the top pin and remove the bottom. Then I just rotate the caliper out of the way.

 

Yes I think that's what I'm talking about. There is a little plastic bushing near the tip of one of the slide pins, but I don't remember if I pulled that one from the top or bottom hole of the caliper.
