Vehicle is 1997 Galant ES, 2.4L, I4, SOHV. I am in the process of replacing the front brake pads and after dismantling noticed that the caliper pins are different. One has a groove for a rubber bushing (to reduce vibration, I assume) and the other is just plain without the groove. The trouble is now I don't know which goes where or even if it matters. Would be grateful if someone can lead me in the right direction. Thanks.
