I spent some time working on the front caliper carriers for my Jetta. These are Girling 60 dual piston brake caliper carriers. They're steel, which takes some time to polish up. The plan is to powder coat these satin black, but I wanted them to be smooth first.
I've finished one so far, here is a comparison with the original piece!
Next I'm going to work on the front calipers. Here is a picture before any work... they're pretty rough!
Lots of sanding left to do!
