Model S / Model S Plaid (2021+) UP x PFC Large Sweep Brake Rotor and Pad Set (For OEM Caliper)
$265.00 - $1,995.00 $212.00 - $1,995.00
TESLA 2021 MODEL S PLAID BRAKE GUIDE FOR HIGH-PERFORMANCE DRIVING
The UP x PFC Front Large Sweep Brake Package is designed to maximize braking performance with the factory Tesla brake calipers. Clever packaging is a key attribute of these kits which is made possible by integrated PFC x UP brake pad/rotor engineering. The result of this packaging provides an 11% increase in pad sweep along with a 6.5% increase in rotor thickness and approx 40% weight savings, all without relocating the caliper.
The pad sweep increase is gained by utilizing a wider annulus rotor and an appropriately sized brake pad to utilize this special pairing. This ensures more usable rotor and pad in the same dimensions, allowing 19″ performance wheel/tire packages to be used (fits all wheels 19-22″). Our engineering ethos around maximizing results with creative integrated engineering keeps rotational mass at a minimum while maximizing brake pad contact area, rotor thickness and therefore maximizing the thermal capacity of the factory calipers.

The rotors included have a world-class pedigree and come from PFC’s Porsche 911 GT3R race car program. They utilize PFC’s patented V3 hats which require no bolts in their hyper-efficient attachment to the rotor. PFC is UP’s exclusive brake partner and is world-renowned for being the global brake upgrade partner chosen by Porsche Motorsports for Porsche competition race cars. PFC engineering and production boasts the highest quality materials to stand up to the harshest of uses on the track. For all of our brake upgrades for Tesla Model S Plaid or Long Range we recommend pairing them with high-temperature racing brake fluid such as Motul RBF 660, PFC RH 665, Endless RF 650, Castrol SRF, or similar racing brake fluids and our Stainless Steel Brake Lines. For track use please combine with our brake duct kit, or competition brake pads and with Tesla’s Track Mode for best results.
- UP x PFC Front Rotors are 34mm vs factory 32mm thickness for increased thermal mass.
- UPxPFC Rotors Diameter size: 380mm
- UP x PFC Front Rotors have a 11% wider annulus than the factory rotor for a maximized sweep.
- UP x PFC Rear Rotor and Pad combination offers 55mm of sweep vs factory 47mm.
- Purpose-built rotor and pad combination for 10% more swept area and a thicker rotor.
- Efficient 2pc lightweight engineering that is approx. 40% lighter (prototypes are 35lbs vs 58lbs for front axle)
- Maximum thermal mass and maximum pad contact/sweep on the stock caliper.
- No caliper relocation is required allowing 19″ wheels/tires (and larger) to be used with the lowest rotating mass for improved acceleration and deceleration.
- Easy replacement of pads and disks independently.
- Choose either Street or Racing & Competition pads, or pick up an extra set so you can easily swap between them.
- We recommend pairing any of our brake upgrades with our UP Stainless Steel Brake Lines and Brake Ducting Kit
- We strongly recommend against attempting to use Large Sweep components independently. Large Sweep rotors should only be used with Large Sweep Pads, and Large Sweep Pads should only be used with Large Sweep Rotors.
- The Front Large Sweep Kit replaces Tesla parts: 1420611-00-C x 2 and 1621000-00-A x 2
- The Rear Large Sweep Kit replaces Tesla parts: 1420631-00-A x 2 and 1562160-00-A x 2
A NOTE ON BRAKE FLUID & HIGH-PERFORMANCE DRIVING:
Brake fluid plays a vital role in the performance and reliability of every brake system, especially in high-performance driving. A professional brake bleed with high-performance fluid is a requirement for the functionality of our brake system. We recommend using Motul RBF 660 (our go-to fluid) or Endless RF-650 brake fluid. Brake fluid should be flushed frequently for race cars in particular because over time moisture content builds and moisture inherently decreases the temperature limit of the brake fluid. Brake fluid and its temperature capabilities matter especially due to the high temperatures the heavy and powerful Model S generates.
The higher temperatures seen in the brake system transfer heat to the brake fluid and when the brake fluid boils those bubbles create air in the brake lines. Air in the brake lines from boiled fluid can create a near-instant loss of the brake pedal. Therefore, using a high-temperature brake fluid and managing brake heat is key to safe braking in extreme environments. Loss of pedal is a different symptom than brake fade and typically a symptom of brake fluids exceeding their temperature range (or alternatively a leak in the system) whereas brake fade is often a byproduct of the brake pads exceeding the operating temperature range. In both cases managing temperatures in a racing environment and adequate testing is typically found in motorsports drivers and always strongly encouraged to get the best and safest result.
We flush our brake fluid after each race and we monitor caliper temperatures for these same reasons on our race cars. Please always feel welcome to talk to our team if you have questions about motorsport use. For street driving the temperatures seen are significantly less and this plays a lesser role although the same fluids are suggested for street cars as well.

Can I run the Large Sweep rotors with my factory Tesla brake pads?
No. Large Sweep rotors work only with Large Sweep pads, and Large Sweep pads work only with Large Sweep rotors. The wider annulus is a matched pairing, so mixing in an OEM pad or rotor defeats the design and is something we strongly advise against. Buy the rotor and pad together, or order the matching replacement pad or rotor when it is time to refresh.
Do I need a brake fluid flush after installing these?
A professional brake bleed with high-temperature fluid is required for the system to work as intended. We recommend Motul RBF 660 or Endless RF-650, since the heavy, powerful Model S pushes a lot of heat into the fluid and boiled fluid can cause a near-instant loss of pedal. Fresh high-temp fluid keeps the pedal firm. Flush it often if you run the car on track.
Does upgrading these rotors and pads affect my Tesla warranty?
Installing them does not automatically void your Tesla coverage. Under the Magnuson-Moss Warranty Act, Tesla would have to show that the aftermarket part caused a specific failure to deny that claim. Keep your factory rotors and pads so you can revert if needed. Note that brake rotors and pads are consumables, so our own 2-year parts warranty covers workmanship rather than normal wear on these items.
What is a Model S Plaid brake upgrade that keeps the stock calipers?
The UP x PFC Large Sweep set upgrades your rotors and pads while reusing the factory Model S Plaid calipers, so you get more braking capacity without a full big brake kit. It uses a wider-annulus rotor and a matched pad to gain 11% more pad sweep and a thicker 34mm rotor versus the factory 32mm. Front prototypes weigh roughly 35lbs per axle against 58lbs stock, about 40% lighter, which cuts rotating mass while raising thermal capacity.
How does a wider-annulus rotor actually improve braking?
A wider annulus gives the pad more usable rotor surface to sweep across, so you generate more friction and spread heat over a larger area within the same wheel space. On this set that means an 11% larger pad sweep and a 6.5% thicker rotor for extra thermal mass, all without moving the caliper. More swept area and more metal to soak up heat is what lets a heavy, fast Model S brake harder, more times in a row.
