TTSPORT DOT 5.1 Brake Fluid
TTSPORT DOT 5.1 Brake Fluid is a synthetic borate-ester glycol fluid built for high-temperature stability and consistent pedal feel in demanding street and performance driving. Engineered to resist vapor lock during repeated hard stops, mountain runs, and track sessions, it helps your hydraulic system stay firm when heat builds up.
Why DOT 5.1
- High dry and wet boiling-point performance for repeated hard braking
- Synthetic borate-ester base resists vapor formation under heat load
- Low-temperature viscosity suitable for modern ABS, traction, and stability control units
- Backward compatible with DOT 3 and DOT 4 glycol fluids
- Supports firm, predictable pedal response under sustained load
Where It Fits Best
Towing & Mountain Use
Long downhill descents and loaded towing where sustained pedal pressure heat-soaks the calipers.
HPDE & Track Days
Entry-level track use and autocross where a higher boiling point reduces fade and vapor lock risk.
BBK Upgrades
A clean fluid flush is recommended any time you upgrade calipers, lines, or master cylinders.
DOT 5.1 vs DOT 5 — Important
DOT 5.1 is not the same as DOT 5. DOT 5.1 is a glycol-ether / borate-ester based fluid that mixes with DOT 3 and DOT 4. DOT 5 is a silicone-based fluid and must never be mixed with DOT 3, DOT 4, or DOT 5.1. Always confirm the fluid type specified in your vehicle's owner manual before adding or flushing fluid.
Service Notes
- Brake fluid is hygroscopic — keep the container tightly sealed and use within a reasonable time after opening.
- Follow the brake fluid service interval listed by your vehicle manufacturer. As a practical baseline, many street vehicles use a 2-year / 24,000-mile fluid service interval, while track users should flush more frequently.
- Glycol-based brake fluid can damage paint. Wipe spills immediately and rinse with water.
- Bleed in the manufacturer's recommended sequence and verify firm pedal before driving.

Frequently Asked Questions
What is the difference between DOT 5.1 and DOT 5 brake fluid?
DOT 5.1 is a glycol-ether / borate-ester based fluid that is compatible with most modern ABS systems and can be mixed with DOT 3 and DOT 4. DOT 5 is silicone-based, is not hygroscopic, and must never be mixed with DOT 3, DOT 4, or DOT 5.1. Always confirm the fluid specification listed in your vehicle's owner manual before topping off or flushing.
Is TTSPORT DOT 5.1 compatible with ABS and ESC systems?
Yes. DOT 5.1 is formulated with low-temperature viscosity characteristics suitable for ABS, traction control, and stability control hydraulic units. It supports fast valve response in modern electronically controlled brake systems.
Can I mix DOT 5.1 with my existing DOT 3 or DOT 4 fluid?
DOT 5.1 is chemically compatible with DOT 3 and DOT 4 glycol-based fluids and can be mixed in an emergency. For best performance, however, we recommend a complete flush so the system runs on a single fluid with known boiling-point and moisture levels.
How often should brake fluid be replaced?
Follow the brake fluid service interval listed by your vehicle manufacturer. As a practical baseline, many street vehicles use a 2-year / 24,000-mile fluid service interval, while track users should flush more frequently. Brake fluid is hygroscopic and absorbs moisture over time, which lowers the wet boiling point and reduces resistance to vapor lock under heat.
Is this fluid suitable for track days?
DOT 5.1 offers high dry and wet boiling-point performance for spirited street, canyon, and entry-level track use. For sustained wheel-to-wheel racing or heavy track abuse, consider a dedicated race fluid and flush after each event.
Will DOT 5.1 damage paint or finishes?
Like all glycol-based brake fluids, DOT 5.1 can damage paint and finishes on contact. Wipe spills immediately and rinse with water. Keep the container sealed to prevent moisture absorption.

Great value filters – do the job well
Pattern Name: 12x12x1, Style: Merv 8
These filters are a great value for the price, especially getting a 6-pack. They fit perfectly (just keep in mind the actual size listed), and installation is quick and easy.
I’ve been using them regularly and they do a solid job catching dust and keeping the air clean without restricting airflow. Good balance between filtration and performance.
Nice to have multiple on hand so I can swap them out regularly without thinking about it. I’ll definitely keep buying these.

Cool, Fluffy, and Excellent Value
Color: White, Size: Queen (Pack of 2)
I recently got the Utopia Bedding Queen Size Bed Pillows (set of 2), and they’ve quickly become my favorite pillows for a good night’s sleep.
Right out of the package, they fluffed up nicely and feel soft yet supportive. The down alternative filling gives a plush, comfortable feel without being too firm or too flat, and the gusseted design adds extra support for back, stomach, or side sleeping. I’ve tried them in all positions, and they hold up well without collapsing overnight.
Another big plus is that they stay cool while I sleep. Even during warmer nights, I don’t feel overheated, which makes a huge difference in comfort. The pillow covers are smooth and feel like hotel-quality fabric, giving the bed a clean, luxurious look.
The only minor thing is that they may take a little time to reach full fluffiness after the first wash, but that’s normal for down alternative pillows.
Overall, these are soft, supportive, and high-quality pillows at a great price. They’ve improved my sleep noticeably, and I’d definitely recommend them for anyone looking for a comfortable, versatile pillow set

Well priced luxury feel.
Color: White, Size: Queen (Pack of 2)
This set of 2 pillows is very luxurious and comfortable to sleep on with good height but not so much as to elevate or lower the head to an uncomfortable degree. I just received them so they need time to air and expand fully but right out of the compacted box they are full and very comfortable. The fabric is very soft and there is no odor. These pillows are definitely a good price for such a luxury item. I think I will enjoy them for some time to come.

Soft...but fluffy and tall
Color: White, Size: Standard (Pack of 2)
I've only had these pillows for about a week. They are a great quality pillow. The cover is soft and seems well made. My only complaint is that they are VERY full pillows. If you're tall with broader shoulders, you'll probably love them. If you're shorter with a smaller frame you will probably feel like your head is too high and your neck at a weird angle (my problem). There seemed to be mixed reviews about softness....I would consider these a nice medium pillow. Soft filling but firm enough that your head doesn't sink to the bed. Definitely NOT a down-like pillow, so if that's what you're looking for, this is not for you.
