Drilled rotors offer sharper initial bite and a more aggressive look but are typically better suited to lighter street use since they can be more prone to stress cracking under extreme heat.\u003c\/p\u003e\n\u003cstrong\u003eWhat color options are available for this kit?\u003c\/strong\u003e\n\u003cp\u003eThis kit is offered in Natural Anodize (Zinc), Red, Orange, Yellow, Green, Light Metallic Blue, Dark Metallic Blue, Silver, Black Hard-Anodize, and White, so you can match the calipers to your Gladiator's look.\u003c\/p\u003e\n\u003cstrong\u003eWhat years and trims does this kit fit?\u003c\/strong\u003e\n\u003cp\u003eThis Rotora rear brake system is designed specifically for the 2020-2023 Jeep Gladiator Sport, Rubicon, Mojave, and Overland trims.\u003c\/p\u003e\n\u003cstrong\u003eWhy does the Zinc finish cost more than the other colors?\u003c\/strong\u003e\n\u003cp\u003eThe Zinc natural anodize finish uses a more involved anodizing process than the standard color finishes, which is why it carries a higher price point than the other nine available colors.\u003c\/p\u003e\n\u003cstrong\u003eHow does this kit compare to the RFK.572.04?\u003c\/strong\u003e\n\u003cp\u003eThe RFK.572.03 uses a 1-piece 328x28mm rotor and 4-piston RF419 caliper, while the RFK.572.04 steps up to a larger 2-piece floating rotor design for greater heat capacity.

New pads and rotors should be broken in with a series of moderate stops from around 45 mph down to 10 mph, allowing full cooling between stops, and avoiding hard braking or extended highway driving for the first 200 to 300 miles.\u003c\/p\u003e\n\u003cstrong\u003eHow many pistons does the caliper have?\u003c\/strong\u003e\n\u003cp\u003eEach RF419 rear caliper in this kit uses a 4-piston forged design for reliable, even clamping force across the rotor.\u003c\/p\u003e\n\u003cstrong\u003eWhat size are the rotors?\u003c\/strong\u003e\n\u003cp\u003eThe kit uses 328x28mm 1-piece rotors sized to clear the Gladiator's factory wheels while delivering a meaningful upgrade over the stock rear brakes.\u003c\/p\u003e\n\u003cstrong\u003eWhat warranty comes with this brake system?\u003c\/strong\u003e\n\u003cp\u003eThe RFK.572.03 is backed by a 1-year Rotora warranty covering manufacturing defects in the calipers and rotors.\u003c\/p\u003e\n\n\u003ch4\u003eInstall Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003ePark the Gladiator on a level surface, engage the parking brake release procedure per your service manual, and loosen the rear wheel lug nuts before lifting the vehicle and securing it on jack stands.\u003c\/li\u003e\n\u003cli\u003eRemove the rear wheels and disconnect the factory brake line from the caliper, capping it to prevent fluid loss and contamination.\u003c\/li\u003e\n\u003cli\u003eRemove the factory caliper, bracket, and rotor, then clean the hub and axle mounting surfaces thoroughly.\u003c\/li\u003e\n\u003cli\u003eInstall the new mounting brackets supplied with the kit, torquing all hardware to manufacturer specification.\u003c\/li\u003e\n\u003cli\u003eMount the new 328x28mm rotor onto the hub, followed by the RF419 caliper and pads, and secure with the provided hardware.\u003c\/li\u003e\n\u003cli\u003eConnect the new braided stainless brake lines to the caliper and to the factory hard line, then bleed the brake system to remove all air.\u003c\/li\u003e\n\u003cli\u003eReinstall the wheels, torque the lug nuts to spec, and lower the vehicle.\u003c\/li\u003e\n\u003cli\u003eCheck fluid level, pump the brake pedal to confirm firm engagement, and road test at low speed before returning to normal driving.\u003c\/li\u003e\n\u003cli\u003eFollow the recommended break-in procedure for the first 200 to 300 miles before subjecting the brakes to hard use.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003eWARNING: This product can expose you to chemicals including brake dust, which is known to the State of California to cause cancer.
