I've had brakes done a few times over the years before I started doing them myself this year. I believe the calipers are still OEM with the exception of one rear that was replaced at some point in the past. I am finding some conflicting information regarding where the slotted Pin A vs smooth Pin B need to go. With the calipers mounted on the vehicle (2005 TL automatic), the slotted pins on the back wheels are now on the top. On the front wheels seems like the smooth pins are on the top. If both boots move freely is the slotted pin placement so critical? If so what is the best way to figure out if it goes on the top or bottom when facing the wheel? Thanks!

You can see the different pins in the diagrams linked

 

Thanks looks like I got it right, it matches what's in the service manual. 50 /50 chance I guess it worked out

 

good enough odds for me too
