These zinc-coated caliper bolts are the perfect replacement for your old and corroded factory hardware. They come as a set of 4 for either the front, rear, or both and are intended to replace the bolts securing the factory 4-piston Brembo calipers to the knuckle.
 
This is for the stock foot brake calipers, not to be used with the StanceCo. Dual Caliper Bracket.
 
Wrench size: 16mm
