Tesla Model 3 and Model Y – BFB Carbon Ceramic Rear Big Brake Kit

Yes. The kit retains OEM functionality for the parking brake and stability control systems, so nothing on the car’s safety side is compromised by the swap. You get the braking and weight benefits of carbon-carbon without warning lights or a dead e-brake. That integration is part of why it is a bolt-on upgrade rather than a race-only conversion.

Carbon-carbon friction gives fade-free operation at high temperatures and vastly reduced pad wear, plus the huge unsprung weight saving. An iron big brake kit costs less and stops hard, but iron is heavier and wears pads faster under sustained heat. If you want the lightest, most heat-immune rear setup and pair it with a carbon front kit, the carbon-ceramic rear is the top of the range.

Between the carbon-ceramic rotors, the 20-inch wheel requirement, and the caliper and harness swap on non-Performance cars, this is a job for a competent brake shop, not a driveway first-timer. A proper brake bleed with high-performance fluid is required for the system to work correctly. We install it at our Hawthorne facility and can sort the non-Performance parts and bleed in one visit.

A professional brake bleed with high-performance fluid is mandatory for this system to function. We recommend Motul RBF 660, our go-to, or Endless RF-650. Fluid matters because heat transfers into it, and if it boils, the resulting air in the lines can cause a near-instant loss of pedal, which is different from pad fade. Flush it regularly, especially if you track the car.

It is designed as the complement to the front carbon-ceramic kit, and the page frames it as the perfect pairing with a front BBK and high-performance tires. Running a big rear alone can upset front-to-rear balance. If you want a matched setup, the Iron 6-Piston Front Big Brake Kit is a natural front partner; if you run that iron front, keep its replacement PFC pads in mind as a service item.

Adding an aftermarket brake kit does not automatically void your Tesla coverage. The Magnuson-Moss Warranty Act means Tesla must show the kit caused a specific failure to deny that claim, rather than pointing at the upgrade itself. Because it keeps OEM parking-brake and stability-control function and retains your factory parts for reversal, it is designed to coexist cleanly with the rest of the car.

This kit jumps the rear from the small 13-inch stock rotor to a 15-inch carbon-ceramic rotor. The larger effective radius multiplies the torque the brake can apply to slow the car, and the floating disc design adds thermal capacity. It is built to pair with a front big brake kit and high-performance tires so the whole car stops in balance, front to rear.

The 15-inch carbon rotor is 9.5% lighter than the stock one-piece rear rotor, dropping almost 3 lbs of unsprung weight per corner including all hardware, at roughly 2.7 lbs saved. Unsprung weight is what the suspension has to control, so cutting it sharpens ride response and reduces the mass the dampers fight. On a heavy EV, you feel that reduction rather than only reading it on a spec sheet.

You need 20-inch or larger wheels to clear these rotors. That is a hard requirement, not a suggestion, because the 15-inch carbon disc is physically large. If you run 18s or 19s, they will not fit over this kit. Before ordering, confirm your wheel diameter, and if you want tire options that suit a 20-inch setup, our team can point you to the right fitments.

It fits the Model 3 (2017-2023 pre-refresh), Model 3 (late 2023 refresh), and Model Y, but non-Performance variants need extra factory parts. Model 3 SR/MR/LR and Model Y RWD and LR require an upgrade to the performance caliper, and the page offers the needed Tesla parts, LR and RR calipers plus wire harnesses, as an add-on. Performance cars already have what they need.

Tesla’s warranty covers factory-installed parts, but it does not automatically void your warranty if you install aftermarket components like Unplugged Performance brake kits. Under U.S. law (Magnuson-Moss Warranty Act), Tesla must prove that an aftermarket part caused a failure in order to deny warranty coverage. Our parts are engineered to work harmoniously with Tesla OEM Brake systems and can be professionally installed by Unplugged Performance in Hawthorne, CA or by an authorized installer to minimize risk. That said, any damage directly caused by misuse or improper installation may not be covered. We recommend retaining all factory parts so you can revert to stock if needed. Many Tesla owners enjoy peace of mind by using Unplugged Performance products, which are extensively tested and installed by certified professionals. If warranty concerns are top-of-mind, our team can help clarify compatibility and installation best practices to ensure a worry-free experience.

Unplugged Performance offers a comprehensive warranty on all parts and installations performed by our certified technicians. Warranty coverage applies to defects in materials and workmanship on items including lowering springs, coilovers, big brake kits, brake pads, stainless steel brake lines, shocks, and more. Should any covered part fail under normal use or display premature wear, we will repair or replace it at no additional cost—assuming the component was installed by us or at one of our authorized partners.

This warranty is valid for 2 years or 24,000 miles, whichever comes first, excluding consumable products like brake pads, rotors, and tires, starting from the installation date. Coverage extends to labor for warranty repairs when performed by Unplugged Performance or an authorized installer. It does not cover damage resulting from misuse, accidents, off‑road use, improper installation not done by us, or modifications that aren’t factory-approved.

To file a warranty claim, simply contact our service team. We’ll guide you through inspection, shipping (if needed), and repair or replacement logistics. transparencia and top-tier support are what you can expect from Unplugged.

Installing aftermarket parts does not automatically void your Tesla warranty. Under the Magnusson-Moss Warranty Act (www.sema.org/sema-enews/2011/01/ftc-validates-right-to-install-aftermarket-parts), a manufacturer cannot void your warranty simply because you installed aftermarket parts. Tesla must prove that the aftermarket part caused the specific failure in question to deny a warranty claim. UP recommends retaining all factory parts to allow reverting to stock if needed.
