Carlube DOT 3 Brake Fluid 500 ml

Product Information

This brake fluid is suitable for top-ups or re-fills of clutch and brake systems in heavy-duty commercial vehicles, motorcycles, and 4WDs, and passenger cars. You can also use it on agricultural, construction, and mining equipment. To ensure the safety and effectiveness of DOT 3 brake fluid, it is important to follow proper storage and handling procedures: Advice, how-to guides, and car care information featured on AutoZone.com and AutoZone Advice & How-To’s are presented as helpful resources for general maintenance and automotive repairs from a general perspective only and should be used at your own risk. Information is accurate and true to the best of AutoZone’s knowledge, however, there may be omissions, errors or mistakes. Most people think that DOT 5.1 is a modification of DOT 5, but that is not the case. DOT 5.1 is silicone-based, and it is a combination of borate ester and polyalkylene glycol ether. DOT 5.1 brake fluid sustains more heat than other DOT brake fluids without any mushy feelings. It can withstand higher dry and wet boiling temperatures and provides superior performance over all the other DOT brake fluids. You can mix it with all the glycol-based brake fluids, but it is not compatible with DOT 5.

It is very important to take care of your brake system, because this is one of those things you really want to function properly in any emergency situation.There are several types of fluid, grouped under two headings: those that are glycol-based and those based on silicone. To choose the right brake fluid for your vehicle, it’s important to refer to the manufacturer’s recommendations outlined in the vehicle owner’s manual. The manual will specify the appropriate DOT specification for the brake fluid. Brake fluid is subjected to very high temperatures, especially in the wheel cylinders of drum brakes and disk brake calipers. It must have a high boiling point to avoid vaporizing in the lines. This vaporization creates a problem because vapor is highly compressible relative to liquid, and therefore negates the hydraulic transfer of braking force - so the brakes will fail to stop the vehicle. [14] Most modern cars use either a DOT3 or DOT4 brake fluid. In essence, these are similar fluids, as they both are glycol-based. The only difference is their boiling point, which is higher for DOT4.

The disadvantage of mineral oil is that it’s unregulated and as a result, not all mineral oils are created equal.DOT 3 brake fluid is designed to perform well under normal operating conditions. However, in extreme weather conditions, such as extremely high or low temperatures, it is advisable to use a brake fluid with a higher boiling point, such as DOT 4 or higher. This is because extreme temperatures can affect brake fluid’s performance and boiling point. Brake fluid is also incompressible, helping to ensure that all the power from the lever is transferred to the pads. It is important to note that the color of brake fluid alone is not a reliable indicator of its condition or suitability for use. Instead, following the manufacturer’s recommended brake fluid replacement intervals and performing regular inspections and testing to ensure the fluid meets the necessary specifications for safe and effective braking performance is recommended. Popular Dot 3 Brake Fluid Brands Prestone DOT 3 Brake Fluid DOT 3 brake fluid has the necessary properties to provide proper operation and performance in ABS-equipped vehicles. It is important to use brake fluid that meets the specifications recommended by the vehicle manufacturer to ensure compatibility and optimal ABS system performance. Can I use DOT 3 brake fluid for racing or high-performance vehicles?

Brake fluid needs to be able to withstand high temperatures and typically has a high boiling point, far above what a brake would be subject to in normal conditions. When we put together a product review, we usually like to give an indication of budget, mid-range, and expensive options. With DOT 3 brake fluids, there isn’t really enough variety for us to do that. These advantages contribute to the widespread use of DOT 3 brake fluid in various vehicles. However, it’s important to note that DOT 3 brake fluid does have limitations, such as its hygroscopic nature and lower compatibility with systems designed for silicone-based DOT 5 brake fluid. Because a hydraulic system is sealed and there are no cables to stretch, it offers more reliable braking. The fluid held in the lever reservoir effectively tops the system up over time as the brake pads wear down, so that braking is consistent. Avoid mixing different types or brands of brake fluid, as this can lead to unpredictable performance and potential damage to the braking system.

What is DOT 3 Fluid?

When you drive your car hard at hills or with a trailer and brake a lot, the brake fluid will heat up fast. If it is heating up too much and starts to boil, you will lose the ability to brake your car, and that is the last thing you want to happen at a hill with a trailer. Therefore, it is important that the boiling point be as high as possible. Changing the brake fluid is one part of taking care of your brake system, and you should replace it once every one or two years. Otherwise, it may cause rust inside the brake system and damage other parts. DOT 4 brake fluid has a higher boiling point than DOT 3 brake fluid. DOT 3 typically has a boiling point around 205°C (401°F), while DOT 4 has a boiling point around 230°C (446°F). And although it’s possible to use a one-person operation using a pressure bleeder for older brake systems, it isn’t recommended for a manual operation for a brake system that requires diagnostic equipment and/or a pressure bleeder.
