In this pic, you can see inside this 2LS front caliper, there are 4 pieces of metal that line the four corners of the space where brake pads sit, as indicated in the pic.
What's the name of the part, and the part number?
Thanks.

 

Hi dashan, I am like bradland, cant see very good.. but see if this helps you..

 

Toyota calls it a Fitting Kit but disregard this part number as I don't know the year of your car.

 

Thanks, but the parts in your pic are no the ones indicated in the picture of my OP above.
