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

      Dominic Marcu - Racing Driver Just perfect for my car

      Want to stand out among other Cybtertrucks? This is a great place to start. If you're trying to decide between the 30mm and 50mm, go with the 50mm. The 2" that it kicks each tire out absolutely toughens the stance of the Cybertruck. I found these spacers to be EXTREMELY well made and easy to...

      Love the look of these as they add a more aggressive look for the front. Same subtle style that goes along very well with the front lip for non-performance M3.
      Christian N. December 23, 2025
      These brakes have been a game changer for the Plaid. It's a bulky 5000lb 1000hp monster and needs brakes that fit the bill. Unfortunately, the stock setup left a lot to be desired especially when climbing towards the higher speeds. At that point, the brake application felt more like a suggestion and...

      The Willans Safety Harness kit along with the Ascension-R Racing seat just arrived from Unplugged Performance (https://www.instagram.com/p/Cv8f-5cvDuE/) The 6-point Harness kit goes hand in hand with the design of the racing seat. It looks absolutely well made and high quality making it a must have...

      Added these high quality RAC arm set to the D&S PRO coilover suspension lift kit. The ride is amazing after installation and alignment. Highly recommend.
      Mike N. January 18, 2025
      Had UP install the HD front bumper with the 11" LEDs. Robust steel construction, makes the truck look more aggressive but lines remain clean. This bumper is what Tesla should have equipped the truck with out of the factory! LEDs are super bright as well. Simply the best looking, best designed,...

      I love the front ascension fascia! Really changes the whole look of the Model 3. My least favorite part of the car was the front bumper and this changed it all for me. Noticeable improvement in downforce as well which is a nice touch. Totally transformed the car and I couldn’t be happier. Also...

      Real cool suspensions the car drives smooth and quite. Made a real difference to the drivability and now I really enjoy driving the car. Absolutely recommend it if your factory shocks have failed. Mine failed in 5 years.
      kerbad October 01, 2024
      Drove on these for 60,000 miles and they were perfect. Never heard any noise from these and it’s such a great and affordable way to increase the performance of your car easily and without a huge financial commitment. Super impressed with what these could do. Highly recommend.
