Wilwood Rear Plain-Rotor Brake Conversion, Red CPB Calipers, Honda Civic Si 2006–2015

The red-caliper, plain-rotor version of this Wilwood Civic Si conversion retains a mechanical parking-brake function within each hydraulic caliper. Its 12.19-inch vented rings and separate hats run with BP-10 pads. The specified floating calipers are part of a rear-disc conversion package, not standalone universal parking calipers. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines. Its product range serves motorsport, street-performance, and specialized applications, with individual components selected to match the requirements of the complete brake system.

Fitment & Compatibility

Match the 2006–2015 Civic Si entry and rear disc hardware, then review DS820 for bracket installation and cable adjustment. The parking cable is mechanical; there is no motor or electronic actuator in this CPB arrangement. Hydraulic hoses must be compatible with the caliper and vehicle routing. Compare the wheel's section to the drawing, because even the conditional 17-inch size does not guarantee spoke clearance. Some 16-inch wheels can be used only if the complete template fits.

Check the individual year, model, submodel and equipment conditions in the fitment table below before ordering.
