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

      I recently installed the these on my Cybertruck, and they’re absolutely fantastic! Made from tough carbon steel with a sleek black powder coat, they blend seamlessly with the truck’s design, looking like a factory upgrade. They came preinstalled on the rocker panels, so setup was a breeze,...

      Getting these installed along with the moderate version of the dual rate springs on my Model 3! Very excited and I cannot wait to see the new look and feel the significant difference.
      Christian N. January 01, 2026
      I really like the new moderate lowering spring for my Model Y performance. The set lowered the car by roughly 1 inch (2.5cm) I have the feeling that the car provides a smoother ride than stock. You feel it when driving over small bumps. The car is still stiff but I like it better that stock and...

      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,...

      Product is top notch when I installed them it was like switching from a 1 piston sliding caliper to a bbk. Also cold performance and noise are really good
      Christos K. November 04, 2022
      I went with the 30mm spacers just to give the Cybertruck a slightly wider stance. These are very well-built. I have put almost 2,000 miles on the truck since installing the spacers and couldn't be happier. The driving dynamic did not change noticeably and I have not noticed a significant reduction...
      Josh H. December 09, 2025
      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...

      If you're looking to upgrade your Cybertruck with functional armor that stays true to its bold design, the Unplugged Performance HD Rock Sliders are an exceptional choice. The build quality is immediately noticeable—these sliders are rugged, purpose-built, and clearly engineered with durability in...

      Installed this on my CyberBeast in my own garage. The instructions provided were top notch with outstanding attention to detail. I installed the bar in the middle position. On the first turn I noticed the decrease in body roll. The turn in and mid turn stability is much improved. I am very...

      I purchased a set of these Sway bars along with a few other upgrade components for my Model 3 (https://www.instagram.com/p/Cv8c-F2PEYP) The sway bars improve the ride quality, reduced body roll making the car more rigid and stable. Installation and setup was easy, being adjustable is an added bonus....
