TESLA 2021 MODEL S PLAID BRAKE GUIDE FOR HIGH-PERFORMANCE DRIVING

When the 2021+ Model S Plaid / Model S comes out of the factory, the vehicle is delivered with rubber brake lines. While rubber is a great option from both the carmaker’s and owner’s perspective, as it is durable, resilient, long-lasting, and most importantly, low cost. However, there are some compromises that come with rubber brake lines, including the ability for the rubber lines to expand and contract under hard braking. This expansion leads to a spongy brake pedal feel, which is actually a loss in the braking capability and response that can be felt.

TESLA 2021 MODEL S PLAID BRAKE GUIDE FOR HIGH-PERFORMANCE DRIVING

When the 2021+ Model S Plaid / Model S comes out of the factory, the vehicle is delivered with rubber brake lines. While rubber is a great option from both the carmaker’s and owner’s perspective, as it is durable, resilient, long-lasting, and most importantly, low cost. However, there are some compromises that come with rubber brake lines, including the ability for the rubber lines to expand and contract under hard braking. This expansion leads to a spongy brake pedal feel, which is actually a loss in the braking capability and response that can be felt.

In turn, to further improve the factory braking capabilities of the 2021+ Model S Plaid / Model S, we’ve developed our Stainless Steel Sport Brake Line Set. For those who demand higher performance and better brake feel from their Model S, this upgrade is something highly recommended. After upgrading to the Stainless Steel Sport Brake Line Set, you’ll notice a firmer and more consistent brake feel during spirited driving. The more-responsive, high accuracy feel will allow for higher confidence and greater precision in braking.

We strongly recommend pairing these upgraded brake lines for your Tesla Model S Plaid or LR with high-temperature racing brake fluid such as Motul RBF 660, PFC RH 665, Endless RF 650, Castrol SRF, or similar racing brake fluids, for maximum performance, as should be done with any brake upgrade.  While these brake lines will function just fine with OEM Dot 4 fluid, the OEM fluid will produce a mushy pedal feel in performance driving conditions, regardless of how stout your brake lines are.

This set includes:

  • 4 stainless steel brake lines tested to 3000+ psi.
  • Laser-cut brackets to replicate the original factory mounting locations and procedures exactly.
  • Crush washers and banjo bolts.

Notes:

  • Customers purchasing our Carbon Ceramic Big Brake Kit aka BFB Kit for the 2021+ Tesla Model S and LR do not need to purchase this brake line kit, as we include these lines with your BBK purchase.
  • Professional installation is recommended.
  • This set replaces the following Tesla PNs:
    • FR LH, BRAKE HOSE, MS, P2 1420723-00-C
    • FR RH, BRAKE HOSE, MS, P2 1420724-00-C
    • LH RR, BRAKE HOSE, MS, P2 1420731-00-C
    • RH RR, BRAKE HOSE, MS, P2 1420732-00-C

      Finally!!!! Been waiting on UP to both have a decent Black Friday sale and to have this item on it and whatdoyaknow…..HALF OFF! I wish it was all gray everywhere, but I’ll do the touch up myself and get it 100% how I need it!!!

      Who likes shredded tires? Nobody! Fix the wonky camber on early Model S vehicles with this easy upgrade.
      bluetrevian March 20, 2024
      Im impressed at the High quality. Love the subtle and clean look.
      Adam M. November 21, 2025
      I've just transformed my Cybertruck into an even more formidable beast, and let me tell you, this is the upgrade you didn't know you needed until you see it. The installation was as straightforward as it gets - a quick clean with alcohol, peel off the tape, press, hold, and voilà! It was like...
      Richard S. February 08, 2025
      Incredibly well tuned for the Model 3. My car is completely flat and on rails through every turn. Very firm in all settings yet still just comfortable enough to daily drive in the first 4 clicks with the oil bypass feature. Super easy to adjust back and forth from weekend driving to daily driving....
      Andrew P. November 03, 2022
      I was tired of replacing my rear tires all the time, between the power and weight of the Model Y P, this camber finally allowed me to dial in my alignment for tire wear and better traction. Will pay for itself with tire savings.
      Jorge (. August 23, 2022
      Great complement to my Model Y's coil overs and sway bar set up. Significant handling improvements overall. Best of all, these camber arms give me the peace of mind of not worrying about uneven tire wear after dropping my ride height 1 inch. Car looks and feels great on the road.
      James_M September 05, 2022
      Worked great, much less brake fade throughout my runs and lets me have more confidence in my stopping power as the heat builds.
      Andrew P. August 23, 2022
      These wheels are insanely light and strong! And, they look the bomb! If I didn’t look while picking them up, I would have thought they are carbon fiber! The same spec as was originally used on the Bionic Phoenix Model 3 race car! I put in my fastest time at Buttonwillow on these wheels running...
      Sof October 03, 2023
      Purchased the sway bar for my plaid about a year ago after hearing good things about it on the Tesla forum. Unfortunately, I got super busy and I didn’t get a chance to install it until recently. Very happy with the purchase and there’s a very noticeable improvement in handling. The car also...
      ANDREW G. May 25, 2023
      I loved upgrading my front brakes to BFB Carbon, after a few track days and realized I want the rear as well, plus now the aesthetics are on point! (look weird with only the front carbon IMO)
      Jorge (. August 23, 2022
      You can see my photos under Steve Guevara. WHEELS, what to say about this indescribable addition. There are so many incredible things added to my SMG3, but this wheel set altered the car drastically. The RIDE is much improved with the grip around tight corners like Topanga Canyon with the other four...
      smgdcw November 17, 2022
      Sway bars changed behavior of car. It was straight forward to install. Thanks to the Unplugged team for providing guidance on the correct way to setup sway bar with the adjustable end links. Very happy with product!
      juanlop687 May 09, 2023
      So this review is based off of two things, product: how well it performed and customer service. So with the pre-yoke model s and x, they’re known for their shutter issue and tire wear, so to fix this, I torn between the links from native or UP. So I decided to go with UP, I got the complete kit...
      quimai25 October 19, 2022
      I recently purchased the UP-03 Race Spec Wheels for my Tesla Model 3 from Unplugged Performance. Although the wheels look great and undoubtedly enhance the driving experience, I encountered a few issues during the process. Firstly, I was not informed that I would need spacers for the UP validated...
      David S. April 19, 2023
      This is a necessary product if you want to properly raise or lower your vehicle. Part is super high quality.
      josephschneider77 November 04, 2022
      Psychologists say that the more you pay for something, the more you like it. Maybe that’s what’s happening here, but the front fenders are now my most cherished upgrade. I love that I can unlock up to a 315mm square setup with a track camber and 305-295mm with a daily camber. I’ll never be...
      David S. November 15, 2022
      Outstanding coilovers, even BETTER customer service! Driving is truly believing. If you’re looking for a smoother ride in your Tesla Y/3, look no further. I can honestly say that with my current setup, the suspension is like night and day compared to stock. Shortly after this install, I just...
      jamesmagno93 August 09, 2022
      These are best brakes I’ve ever experienced on any car! Like Randy Pobst said, just looking at these brakes gives confidence. In practicality, they work so well on the street with instant bite and heavy stopping power. Check out this post of my Tesla Performance Model 3 stopping from 60Mph in 2...
      Sof October 11, 2022
      Love the look of the spoiler, improves efficiency, mailing up for some of the battery degradation.
