Question for you guys.. I am in the middle of a brake job for my Civic Si and noticed for both the front and rear calipers there is a grooved and smooth caliper slide pin..?

Well, I did not notice until I had everything torn apart and cleaned and when I started reassembly I never took note on which pin goes in the top and bottom?

So, for the front caliper does the grooved pin go in the top or bottom hole?

For the rear caliper does the grooved pin go in the top or bottom hole?

Thanks guys.

 

Im looking up at the parts blow up and i can only see that one pin has a plastic washer type thing on the end of one of the pins....Ill assume that it is 06/11?
Let me know

Edit... Groved pin goes on the bottom and the smooth one on top...

 

For both front and back calipers, the slide pin with the taper/groove goes on the bottom.

 

Thanks guys, may I ask why they are different and what effect it would have if they were reversed?

 

the same thing happened to me when i did my brakes about a year and a half ago. I got them mixed up and had to switch them around the next day.

I was told that if left alone, eventually the pins would lock up the caliper after some amount of time, causing it not to slide properly, and drag the pads on the rotor.

 

so what does the g stand for on caliper?

 

This guys knows what he is talking about
