I know this isn't an S2000 caliper but I replaced the caliper on my Accord and didn't take notice which pin was top and which pin was bottom. They are different, one of them has ridges running lengthwise, the other is smooth.

According to the pic, looks like the bottom pin has the grooves....

couldn't be sure unless I took my accord apart

Thanks for the reply billman.

Yea, according to that pic the grooved pin goes on the bottm. The Haynes (yea they suck, Helms on order) manual I have show this grooved pin on the top.

I guess I'll just have to take apart the other side to be sure and for piece of mind.


So the question remains, what is the purpose of the grooved pin?

Billman250

Good question.

The grooves alllow for the grease to have a place to go.

Billman250

So only one pin needs grease? I'd buy that if they were both grooved, but it's only one. I see it all the time.

Well, I tore apart the other rear caliper to see which pin went where and IF the left caliper has never been apart (I'm the 2nd owner) then the diagram above is WRONG. The grooved pin was on the top of my left rear caliper.

In any case, the rear calipers on my 99 Accord EX V6 are now built identical.

Come on Slows2k, you can do better than that.

As a side note, the non-grooved pin had a rubber bumper on the tip of it.

Only thing I could think of guys. I has a rough New Years, too much I'm still in recovery

This is a right rear caliper, Accord EX-V6 model, the caliper sits behind the axle. Just to prove the microfiches is wrong. Kinda' odd for Honda IMHO.

Top pin is grooved, bottom pin has the rubber tip.
