AP Racing 2-piston brake caliper CP6120 (left), 12.7 mm brake disc

The AP Racing CP6120-3S0 brake caliper is a 44.5 mm 2-piston aluminum caliper designed to work with a solid brake disc up to 282 mm in diameter and 12.7 mm thick. This version is intended for LHT or RHL mounting, depending on the caliper’s position relative to the wheel axle.

Part of AP Racing’s competition range, the CP6120 features a radial mounting configuration with a 130 mm mounting center distance. Its two-piece cast aluminum alloy body and aluminum pistons result in a weight of 1.5 kg, excluding brake pads.

AP Racing specifically recommends this family of calipers for Formula Ford applications and rear braking in rallying. The pad support is provided by a pin, and the manufacturer also offers a version with hose protection for certain rally applications.

Part number CP6120-3S0 uses brake pads from the AP Racing CP5119D50 series. For integration into a specific braking system, the disc sizes, center distance, offset, and caliper mounting position must be verified prior to installation.
