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

      After using the fascia for over two years, this feels like a must-have Tesla upgrade. The stock Model 3 just doesn’t look the same anymore. I would recommend epoxy over double-sided tape to secure the ultrasonic sensors for a longer-lasting, flush fitment.

      An obviously better compound than stock. Once you get them up to heat they performance impeccably. One of the biggest problems I had was brake fade and fear of not having enough braking capability as I continued with my runs and this is one of the products that helped fix that.

      Billet Adjustable Rear Camber Arm Set for Tesla Model S and Model X (2012-2020)
      Essential upgrade for Model S and especially a Gen 1 which has excess rear negative camber which contributes to significant uneven tire wear. Combine that with a proper Unplugged alignment and your Model S will be driving better than it did from the factory.
