When you press the brake pedal, you push a piston within the master cylinder, which forces the brake oil through rigid metal lines. This pressure is then transferred evenly to the pistons in the calipers or wheel cylinders, pushing the brake pads against the rotors.
Understanding Brake Oil Fluid Types and Their Importance
The Critical Need for High Boiling Points Not all liquids behave the same way under heat, and brake oil faces extreme thermal stress. 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.
Because the fluid cannot be compressed, the energy from your foot is transmitted instantaneously and reliably to stop the vehicle. The most common types you will encounter are DOT 3, DOT 4, and DOT 5.

Signs of Degraded Fluid. Conversely, DOT 5 is a silicone-based fluid used primarily in military or classic cars due to its unique properties, but it is not compatible with the rubber components found in most modern vehicles.
