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

      We are loving our new UP Luxury Coilovers on our 2021 Model Y! The improvement is noticeable at level 8, the car handles bumps much more smoothly, and the handling seems to have improved as well. I worked primarily with Kirk and he was great. Very approachable and easy to talk to. He talked...

      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
      Best thing I’ve done to my Model 3- by far! Transformed the whole car. Looks better, rides better and handles so much better. Being able to just damping is awesome and super easy. Got these coilovers on in April and immediately drove it on a 4500 mile road trip and noticed the difference right...

      After lowering my car I had some bad rear tire wear because I wasn't able to get a good alignment with the stock arms. This was a quick and easy fix :) 10/10
      Andrew P. September 07, 2022
      These Rear brakes was a big help with our S Plaid drag racing car.Feels great and paired with the Front (BBK) & Upgraded to Racing brake fluid with the stainless steel lines. Thanks
      '@EvSmokeATX November 10, 2022
      The wait for these brakes was well worth it! My Plaid is now much better under braking than with the stock brakes, and I feel more confident both on the road and on the track. Ross helped me with my order and recommended the race and competition compound since I am located in Florida and the warmer...
      martinelava688 September 23, 2022
      Installed front big brake kit and noticed extreme improvement over stock model x plaid brakes. Later installed the rear carbon ceramic rotors and pads and noticed an appreciable increase in braking power and am now quite comfortable braking from speeds in the 160mph range and that was not the case...
      patch2u17 May 09, 2023
      I had my Coilovers installed by NV Auto in Hamilton Canada. They did a good job and I now have a great ride. After about a month of driving I went one step further and put new 18” rims and tires on. This really improved the ride and is is a joy to drive my Tesla again. Thanks unplugged...
      lutzlind August 18, 2023
      Loved the dual rate feature. A more comfortable ride for daily driving and a stiffer more controlled feel for spirited driving!
      Andrew P. August 23, 2022
      Great emblem to have installed and matches OEM emblems.
      Christian N. December 04, 2025
      I received the lower compliance Aft arms today (fri), after ordering on mon. I wasn't sure I'd have time to install, since I already had a lot on my plate, but this afternoon I had a couple spare hours, it ended up only taking about 45 min, including getting the Tesla on jack stands. my...
      Rob T. November 09, 2025
      These dual rate springs were the most noticeable and effective upgrade I've made to my Model Y. Much better handling and comfort compared to the stock standard rate springs.
      davidseldenbrooke March 02, 2023
      Dominic Marcu - Racing Driver perfect! with their help I can have the desired setup for the competition car.
      Dominic M. April 12, 2023
      While the overall weight reduction isn't much in totality, it is noticeably lighter compared to the original lug nuts.
      Josh H. November 17, 2025
      Tesla will just replace the entire control arm, with THE SAME inferior rubber bushing. Was happy to find these UPGRADED bushings to solve the problem for good. Excellent customer service as well.
      James T. January 15, 2025
      My Model Y's overall ride quality and handling performance SERIOUSLY improved after getting this sway bar set installed! I can't get over how much more fun my Model Y is to drive now. I was so excited to put these to the test after getting them installed. The very next day, we went on a road trip...
      James_M September 05, 2022
      I bought my spoiler as soon as my new Model 3 2021was delivered to Vancouver in March 2021. A friend of mine had suggested getting this one specifically and when we added it to my new white Tesla with its dark glass roof-and my extra tinted windows this Black Carbon spoiler added a perfect finishing...
      Brian M. September 29, 2022
      Excellent product from a great team with great customer service! The factory Model 3 Performance's suspension is rather underwhelming, so once you add the Dual Rate Linear Springs along with the Sway Bar kit and Luxury Suspension Kit it completely transforms the car! UP also stands by their product...
      Chris February 27, 2024
      Such an underrated improvement to my car, reducing unsprung weight of each wheel rotating at speed, improves steering, cornering performance and very aesthetically pleasing! It's incredible how much lighter they are from the stock lug nuts, which feel like heavy weights after handling these titanium...
      Sof October 19, 2022
      These bearings were installed for me by a shop that unplugged put me in touch with. Their service was excellent. The bearings were able to be installed with zero use of heat, unlike bearing kits for other cards and potentially from other brands. The road feel and confidence in the back end is...
