Ask a question: 

Does dot4 handle higher heat?

ANSWER

As already stated, DOT4 handles higher heat. If your car is calling for DOT4, that means that the manufacturer does not feel comfortable that the braking system will not raise the brake fluid above a temperature that DOT3 can handle.

What is Dot 4 brake fluid used in?

While both fluids are glycol ether based, DOT4 contains a certain amount of borate ester which allows it to handle more heat. While DOT5 has a higher boiling point (500F dry/356F wet) than DOT3 or DOT4, DOT5 exhibits more compressibility than glycol ether brake fluid. Also, what happens if you mix DOT 3 and DOT 4 brake fluid?

Does DOT 4 fluid always have a higher boiling point than ? A2A-Lukas Sach Absolutely , it is a certified requirement by specification DOT 3 205 °C. (401 °F.) Dry 140 °C. (284 °F.) Wet DOT 4 230 °C. (446 °F.) Dry 155 °C. (311 °F.) Wet There are no specific requirements for the chemical structure however, a

what is the difference between DOT3 and DOT4 brake fluids ? As already stated, DOT4 handles higher heat. If your car is calling for DOT4, that means that the manufacturer does not feel comfortable that the braking system will not raise the brake fluid above a temperature that DOT3 can handle. Another point to make here is there are two boiling temperatures for brake fluid, Dry and Wet.

What is the Difference Between DOT3, DOT4 and DOT5 Brake ?

Most applications call for a DOT3 (401F dry/284F wet) or DOT4 (446F dry/311F wet) fluid, which is considered a higher performance fluid since it can handle more heat. While both fluids are glycol ether based, DOT4 contains a certain amount of borate ester which allows it to handle more heat.

What is The Difference between DOT 3, DOT 4 and DOT 5 ? It has a dry boiling temperature of 356 degrees. Most of the new brake rotors are thin and small, and thus they disperse a lot of heat. This silicon-based brake fluid is ideal for this type of car since it can withstand high temperatures. A DOT 5 brake fluid does not absorb moisture, and it does not cause any harm to painted surfaces.

What are the differences in DOT 3, 4, and 5 brake fluids ? Brake fluid serves more than one purpose. Apart from the main task of providing hydraulic pressure is it is also acts as a lubricant for the rubber components in your master cylinder, wheel cylinders and callipers. Brake fluid also has corrosion i

WHAT EVERY VEHICLE OWNER SHOULD KNOW ABOUT BRAKE …?

Generally, a higher DOT number represents a higher boiling point – so DOT4 would have a higher boing point than DOT3, making it more suitable for more rigorous applications. Choosing the right brake fluid for your vehicle is not merely based on the simple premise that if DOT5 is higher than DOT4 then choosing DOT 5 is better.

When should I use DOT 5 brake fluid? While both fluids are glycol ether based, DOT4 contains a certain amount of borate ester which allows it to handle more heat. While DOT5 has a higher boiling point (500F dry/356F wet) than DOT3 or DOT4 , DOT5 exhibits more compressibility than glycol ether brake fluid.

Which brake fluid? DOT 3 and DOT4 are basically the same, with the exception that DOT4 can handle higher heat and has extra detergents to prevent rubber failure. Stick with DOT 3 unless you are changing and flushing the entire system, there isn't any preformance gains by changing fluid, but if you change to braided lines where there is just plain rubber lines
