Your old brake calipers would have the old clips in them. Look at your old calipers regarding how the clips are mounted, then do the same with your new clips and remanufactured calipers.

 

I don't have the original 97 calipers because I have a 2nd gen Avalon with the single piston calipers. I am wanting to upgrade the 2nd gen back to the 97 dual piston units but I don't have an example to use. The 1st gen Avalons are pretty rare around here, I don't remember ever seeing one at the salvage yards.

I did find a video from TRQ for a 1996 Camry that looks like almost the same calipers and she shows how to put the little clips in. The caliper brackets have these little bosses on the outside of each area where a clip goes and they are different sizes so I didn't know if you had to put them in a certain way but they could be just casting remnants or something. They don't seem to be present on the machined caliper brackets she is using in the video.

 

First 8 clips go in the abutment, next 2 are sequel or wear sensors, wires into holes in pads top and bottom. The abutment holds the caliper they clip in. Wear sensors go in the direction of travel.
