The issue is that all of these cars have single-piston sliding calipers, and the caliper slides on metal pin, but with a rubber bushing. The brake can feel really squishy and cause uneven pad wear due to the flexibility in the rubber, especially as the pads get low and the piston is extended.
These metal replacements are very common for track cars and BMWCCA club racing.
