The Unseen Upgrade: High-Performance DOT 5.1 Brake Fluid

Your big brakes are worthless if your fluid boils. Brake fluid is the most critical and overlooked component in any performance braking system. Under the intense heat of track days or aggressive canyon driving, factory-fill fluid can boil, creating vapor bubbles in the lines. The result is a terrifyingly soft, spongy pedal and a complete loss of braking power—a phenomenon known as brake fade.

TTSPORT DOT 5.1 Brake Fluid is the solution. Engineered with a high-purity synthetic borate ester base, it provides the extreme thermal stability and high boiling points required to maintain a firm, consistent pedal and predictable stopping power, even under the most punishing conditions. It's the essential lifeblood for any performance braking system.

Technical Specifications vs. DOT Standard

The numbers don't lie. Our fluid is engineered to significantly exceed the minimum requirements for DOT 5.1, providing a greater margin of safety and performance when you need it most.

Performance Metric TTSPORT DOT 5.1 DOT 5.1 Minimum Standard
Dry Boiling Point > 270°C (518°F) 260°C (500°F)
Wet Boiling Point > 180°C (356°F) 180°C (356°F)
Viscosity at -40°C < 900 mm²/s 900 mm²/s (Max)

Engineered for Performance and Protection

  • Elite Thermal Stability: The premium borate ester base and advanced additive package resist thermal degradation, ensuring consistent performance and a firm pedal during prolonged, high-heat use.
  • Superior Fade Resistance: With class-leading dry and wet boiling points, our fluid provides the ultimate protection against vapor lock and brake fade during intense braking events.
  • ABS & System Compatibility: Maintains a low viscosity even at extreme temperatures, ensuring a rapid response for modern ABS, traction control, and stability control systems. Fully compatible with all common seal and hose materials.

Frequently Asked Questions

What's the difference between DOT 4 and DOT 5.1?

Both are glycol-based fluids and are compatible for mixing. However, DOT 5.1 is required to meet a higher performance standard. It has a higher boiling point than standard DOT 4 and, more importantly, a much lower viscosity (it's "thinner") at cold temperatures, which is critical for the proper functioning of modern ABS and stability control systems.

Why is the "Wet" boiling point so important?

Brake fluid is hygroscopic, meaning it absorbs moisture from the atmosphere over time. This water contamination drastically lowers its boiling point. The "wet" boiling point (tested with 3.7% water content) is the most realistic measure of a fluid's long-term performance. A high wet boiling point means your brakes will remain safe and consistent, even after a year or two of service.

Can I mix this with my old brake fluid?

While DOT 5.1 is chemically compatible with DOT 3 and DOT 4 fluids, we strongly recommend a full system flush. Mixing new fluid with old, contaminated fluid will immediately lower the boiling points of the new fluid and compromise its performance. For best results, always bleed the entire system and refill with 100% fresh TTSPORT DOT 5.1 fluid.

Is this the same as DOT 5?

NO. This is extremely important. DOT 5 (not 5.1) is a silicone-based fluid and is NOT compatible with glycol-based fluids like DOT 3, 4, or 5.1. Never mix them, as it will cause severe damage to your braking system.

The Finishing Touches: Ordering Brake Accessories

The big parts get all the glory, but the right accessories are what separate a good brake setup from a great one. Here’s how we help you get the exact supporting parts you need, from high-performance fluid to custom brackets.

  1. Tell Us What You're Working With.

    Give us the rundown on your vehicle (make, model, year, VIN) and your current brake setup. Knowing your caliper and rotor specs, plus how you drive, helps us nail the fitment.

  2. We'll Pinpoint the Right Parts.

    Our team will recommend the perfect accessories for your system—whether you need stainless steel brake lines for a firmer pedal, high-temp brake fluid for the track, or custom-machined caliper brackets and rotor hats for a bespoke build.

  3. You Confirm the Details & Order.

    We'll present you with the options. You review the recommendations, finalize your choices, and complete the order easily through our website or a custom invoice.

  4. We Assemble Your Kit.

    Once you give us the go-ahead, we gather all the correct components, double-check compatibility, and assemble your tailored accessory package.

  5. We Inspect, Pack, and Ship.

    Everything gets a final quality check before being securely packed. As soon as it's on its way, we'll send you the tracking info so you can follow it to your door.
