{"product_id":"rear-brake-kit-with-2-or-4-piston-calipers","title":"Rear Brake Kit with 2 or 4-Piston Calipers","description":"The calipers are constructed from a single piece of aircraft-grade aluminum, ensuring lightweight strength and resistance to corrosion. Inside, aluminum pistons are employed for superior heat resistance and consistent operation.\n\nThis particular rear big brake kit features lightweight 4-piston aluminum calipers, which are designed to improve pad wear and increase caliper rigidity compared to factory components. Complementing the calipers are two-piece rotors, which offer a balance of light weight, fade-free performance on the track, and comfortable operation for daily driving. The kit includes Ksport's SC5 Street Pads (NAOC Ceramic), optimized for street use with occasional track days, providing reduced dust and noise while operating effectively between 194°F and 1022°F.\n\nFurthermore, the kit includes D.O.T. compliant stainless-steel braided brake lines. These lines prevent hose expansion under pressure, leading to a quicker pedal response and a firmer pedal feel compared to standard rubber lines. Customers can also choose between slotted or cross-drilled rotors, with cross-drilled recommended for daily drivers due to better cooling, and slotted rotors favored for track use.\n\nKsport Big Brake kits are built to order and typically require 4-6 weeks for production and delivery. This specific kit is confirmed to fit the 2014-2016 Mazda 3. If you encounter any fitment issues and our sales team confirmed compatibility, we will work with you to make the return process easier, potentially waiving restocking or return shipping costs if the error was on our part.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868628873528,"sku":"BKMZ320-443CO","price":3566.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687994018.webp?v=1787915605","url":"https:\/\/store.motormia.co\/products\/rear-brake-kit-with-2-or-4-piston-calipers","provider":"MOTORMIA","version":"1.0","type":"link"}
