What is the purpose of the 4-piston design?

The 4-piston design in this caliper allows for more even pressure distribution across the brake pad surface. This generally leads to improved stopping power and better modulation compared to calipers with fewer pistons.

Does this caliper come with the Anti-Rattle Spring?

No, this caliper is designed for use with the Anti-Rattle Spring, part number PM7159, but it is not included with the caliper itself. You will need to purchase that separately to ensure proper operation and quiet performance.

What does 'Black Ops' refer to on this caliper?

The 'Black Ops' designation refers to the specific finish applied to this Performance Machine caliper. It's a cosmetic treatment that gives the caliper a unique, stealthy appearance.
