Brake fluid is a crucial component of your vehicle’s braking system, playing an essential role in your safety on the road. This hydraulic fluid converts the force you apply to the brake pedal into the pressure needed to stop your vehicle effectively.
Most brake fluids are hygroscopic, meaning they absorb moisture. This property helps lubricate moving parts in the braking system and prevents rust by soaking up moisture that enters the system.
Types of Brake Fluid
There are several types of brake fluid, each with specific characteristics and uses:
DOT 3, DOT 4, and DOT 5.1: Glycol-based fluids that are hygroscopic, meaning they absorb moisture. These are the most common fluids used in modern vehicles.
DOT 5: A silicone-based fluid that does not absorb water. It is typically used in classic cars and specialty vehicles that require a non-petroleum-based brake fluid.
Important: Never mix different types of brake fluid, as doing so could lead to corrosion and other system issues. Never mix different types of brake fluid, as this can cause corrosion and other issues. Check your owner’s manual or master cylinder cap to determine the correct type for your vehicle and always follow manufacturer recommendations.

- Dark brown or black fluid
- Ineffective braking
- Spongy or soft brake pedal

Brake fluid should be changed every 2-4 years or approximately every 45,000 miles. Regular maintenance is essential for a safe braking system.
