    Help identifying brake calipers!!!

    I have some gen 3/4 calipers that I need help identifying. Looking to sell them but I need to know which is which. Each half of the casting has a different number. I have a feeling I may have 3 left rears and one left front. There are stickers on the bottom that say "LR 493AA" with a square, and "LF495AA" with a triangle.

    Any ideas?

    Pop the pads out and measure the dia of the pistons. There will be two different sizes within each caliper. Measure the diamenter of the largest piston in each caliper. The fronts will have a 44mm (1.73 inches) large piston and the rear will have a 42 mm (1.65 inches) dia large piston.

    It does look like 1 Left front and 3 Left rears. If you measure the pistons you will know for sure.
