Brake fluids are hydraulic fluids used in brake systems to transmit force from the brake pedal to the brake components. They must withstand high temperatures and resist moisture absorption.

Types:

• DOT 3: Glycol-based fluid, suitable for most vehicles using disc and drum brakes.
• DOT 4: Higher boiling point than DOT 3, suitable for vehicles with ABS systems.
• DOT 5: Silicone-based fluid; non-hygroscopic and suitable for specialty applications.

Applications:

Used in all types of automotive braking systems, particularly in sport and heavy-duty vehicles where performance is critical.
