Hello All! Here's a pic of a front caliper on my MY99 Classic Wagon, showing some

markings, am wondering if anyone can identify the manufacture. There are 3 triangles which I've ringed, and thought they were Mitsubishi, BUT, Mitsubishi marks are similar but are 3 diamonds, not triangles.... I know that the '5706' marks mean 57mm piston diameter, and that's about It.

 

It’s OEM Subaru, the three triangle symbol is a quality control mark.
