Does different brake fluid make a difference?
Their primary differences are their wet & dry boiling points and their composition. DOT 3 is the most common type used in cars and trucks today. DOT 4, however, is gaining popularity due to widespread use of anti-lock braking systems and traction control, which benefit from DOT 4 fluid’s lower viscosity.
Does it matter what type of brake fluid I use?

What type of brake fluid do most vehicles recommend?
DOT3
Most vehicles in the USA take DOT3 or 4 which are amber in color, like a light beer. They are glycol-based and will absorb moisture out of the air (hygroscopic is the science term). Thus, you’ll want to keep the top of your bottle tight and don’t open the master cylinder reservoir unless needed.
What can I use as a substitute for brake fluid?

Since DOT 4 and 5.1 are both glycol-based brake fluids they are compatible with each other, which means they can be readily mixed without harming your brake system. It is important never to mistake DOT 5.1 (glycol-based) with DOT 5 which is silicone-based and should never be mixed with any other DOT fluid.

Which is better dot 3 or DOT 4 brake fluid?
DOT 3 is the winner in this comparison section between DOT 3 vs DOT 4 brake fluid. It functions well in both water and open air because it has both wet and dry boiling capacity. DOT 4 has an excellent dry boiling capacity but it does not work well in water.
What are the different types of brake fluids?
The three main types of brake fluid now available are DOT3, DOT4 and DOT5. DOT3 and DOT4 are glycol-based fluids, and DOT5 is silicon-based. The main difference is that DOT3 and DOT4 absorb water, while DOT5 doesn’t. One of the important characteristics of brake fluid is its boiling point.
