LIQUI MOLY DOT 4 Brake Fluid, 1 Liter (Pack of 1)

This is my go-to DOT 4 brake fluid, and I’ve been using it on my 25-year-old BMW for years. I recently performed a full brake fluid flush and bleed, and this fluid really brought my braking power back to what it felt like when the car was new. Of course, changing the pads and rotors at the same time helped, but the brake fluid itself made a noticeable difference. Since my BMW uses the same reservoir for the clutch, I was also able to bleed the clutch with this fluid, which resulted in smoother shifting. Reliable, high-quality brake fluid that I’ll continue to use.

Excellent product, works perfectly for my 2921 BMW X4

brake fluid and good quality, been using their products for years. If you ever owned a German car likely you will run across people talking about their products price is very fair compared to other brands.

I am in the habit of changing my brake fluid occasionally. I live in a part of the country that usually has very high humidity. Brake fluid absorbs that moisture and that is the limiting factor on brake fluid life in these humid areas. If a vehicle is only rarely driven or only on short drives, it often doesn't ever get hot enough to force off the water. So, here I am, swapping my brake fluid. This DOT4 fluid is a spec-meeting fluid with a nice package of corrosion and oxidation inhibitors (yes, I checked). It also has a moisture control additive that doesn't stop hygroscopic water gain, but does stop it affecting fluid performance. Brake fluid is one of those problem fluid that the interval is so long you forget. So just change it every 50K or 3 years and you're golden. Do it yourself. It's easy.

Best price in could find, and I didn't have to search hard!

You can’t go wrong with liquid Molly.

I used this Liqui Moly DOT 4 fluid for a brake flush, and the difference in pedal feel was noticeable. After bleeding the lines, the pedal became firmer and more consistent, especially under repeated braking. Liqui Moly has a good reputation for quality fluids, and this product fits that pattern. The one liter bottle is a convenient size. It is enough for a full flush on most passenger vehicles with a bit left over, but not so large that you are storing extra fluid for years. The cap seals tightly and the label clearly shows DOT rating and specs. As with all brake fluid, careful handling is important because it can damage paint. Using a small funnel and some shop towels, the job went smoothly. For anyone who likes to keep their braking system fresh, this is a solid DOT 4 choice.

I swapped out my dot3 for this dot4 fluid in my Chevy Colorado and noticed it works just as good, if not better.
