Valvoline DOT 3 and 4 Brake Fluid
Premium grade brake fluid designed for all ABS, drum or disc brake systems requiring DOT 3 or DOT 4 fluid. Featuring a high dry boiling point, Valvoline™ Brake Fluid reduces the risk of fluid evaporation and possible brake failure and the low-moisture formula provides excellent vapor lock protection for maximum braking performance, while also gaurding against corrosion.
- Compatible with all DOT 3 & DOT 4 fluids
- Low moisture activity
- Maximizes ABS performance
- Ideal for hydraulic & disc brake
- Mixes with conventional brake fluid
- Meets all Federal Motor Vehicle Safety Standard (FMVSS) No. 116 & SAW J1703 specifications
Brake fluid attracts moisture, so it should always be stored in a dry place with the cap securely tightened. Before opening the master cylinder, clean the surrounding area to prevent dirt or grease from contaminating the brake fluid. Do not open the master cylinder outdoors when it is raining or snowing. Do not open the master cylinder in an area of airborne dust or dirt. Check the fluid level and fill the reservoir to the level recommended by the vehicle manufacturer.
How does brake fluid work?
As a hydraulic fluid, brake fluid multiplies the force your foot places on the brake pedal and applies it to the brake pads, which creates friction on the rotors to slow the vehicle.
How often do I need to change my brake fluid?
Most auto manufacturers recommend changing or flushing glycol-based brake fluid every 1-2 years. This is because brake fluid is hydroscopic, meaning it attracts water. Over time, water is absorbed into the brake fluid through hoses and seals and can cause decreased performance and even brake failure.
What’s the difference between DOT 3, DOT 4 and DOT 5?
Since brakes generate friction, which generates heat, your brake fluid must be able to withstand high temperatures. DOT ratings refer to different boiling points that the fluid can withstand. Consult your owner’s manual to make sure you’re using brake fluid that’s safe for your vehicle.
