Tech Tip: CJ Pony Parts has confirmed that the Factory 2013-2018 Y Spoke Focus ST wheel will clear this brake kit.

Included in this kit are a pair of Red or Black Combination Hydro-Mechanical Parking Brake Calipers. These calipers use hydraulic pressure from the stock master cylinder for maximum stopping power. With a functional parking brake, these calipers use an internal mechanical lock within each caliper for the parking brake. The calipers are coupled with oversized two-piece rotor assemblies with aluminum hats and high friction BP-10 compound pads.

Also combined with the rear brake calipers, come larger 12.88” drilled and slotted rotors. With a drilled and slotted design paired with a larger surface area for braking, you can count on a drastically reduced chance for heat-induced pedal fade. This cross drill & face slot design improves the responsiveness of the brakes and capitalizes on pad performance throughout the full range of light-to-heavy braking. The venting and cleaning of the holes and slots will diminish pad glaze along with dispelling hot gasses and heat that is generated from the friction of high-performance track driving.

The 2-piece 12.88" rotors are incorporated with big brake series hats that are specially made from premium aluminum alloys for quality strength and attention to minimized weight. The hats also come with a black e-coat finish to help fight against rust and corrosion. Each rotor is also finished with a black electro coat that protects against both rust and corrosion.

DOT approved flexline kits are included which are required to adapt these Wilwood calipers to your chassis brake lines.

*This kit only fits 18" or larger wheels. Check the wheel clearance diagram in the installation instructions before purchase.
