Pyroil DOT 4 Brake Fluid
Pyroil™ DOT 4 Brake Fluid is specially designed for vehicles with anti-lock (ABS), disc or drum braking systems and is compatible with systems requiring both DOT 3 and DOT 4 brake fluid. By maintaining a high dry boiling point, Pyroil DOT 4 Brake Fluid effectively reduces the risk of fluid evaporation. The low moisture formula ensures maximum braking performance and the addition of corrosion inhibitors protects and prolongs the life of brake system components.
- Provides superior braking power
- Low moisture content
- Mixes with conventional DOT 3 and DOT 4 brake fluid
Consult owner’s manual to find out exactly what kind of brake fluid to use. 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. Store brake fluid in its original container with the lid securely tightened and store in a dry place.
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 do DOT ratings mean?
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.
