Standard Dry Boiling Point Wet Boiling Point Common Use DOT 3 401°F (205°C) 284°F (140°C) Everyday passenger cars DOT 4 446°F (230°C) 311°F (155°C) Modern sedans and SUVs DOT 5. The result is a spongy brake pedal, known as brake fade, which drastically reduces braking efficiency and can lead to complete system failure during emergency stops.
Recognizing the Signs of Brake Oil Failure
The Critical Need for High Boiling Points Not all liquids behave the same way under heat, and brake oil faces extreme thermal stress. This vaporization creates bubbles in the lines, which compress easily.
1, which are glycol-ether based and designed to absorb moisture. Brake oil, often referred to as brake fluid, is the silent sentinel of your vehicle's stopping power.
Recognizing the Signs of Brake Oil Failure and Spongy Pedals
The most common types you will encounter are DOT 3, DOT 4, and DOT 5. This specialized hydraulic fluid transmits the force you apply to the brake pedal directly to the wheel cylinders or calipers, enabling the friction necessary to halt your momentum.
