Understanding Brake Fluid: Types, Composition, and Maintenance
Brake fluid is a crucial component of your vehicle’s braking system, transmitting the force applied on the brake pedal to the brake pads, allowing your car to stop effectively. Here’s everything you need to know about brake fluid, including its composition, types, differences, and maintenance tips.

What is Brake Fluid?
Brake fluid is a hydraulic fluid designed to work under high pressure and temperature, ensuring smooth and efficient braking. Its unique properties make it essential for vehicle safety and performance.
Composition of Brake Fluid
Brake fluid is typically composed of the following:
1. Glycol-ether: Found in most brake fluids like DOT 3, DOT 4, and DOT 5.1. It is hygroscopic, meaning it absorbs moisture over time.
2. Silicone: Used in DOT 5 brake fluids, which do not absorb moisture and are commonly used in specific vehicles like classic cars.
3. Additives: These enhance corrosion resistance, improve lubrication, and ensure the fluid remains stable under varying temperatures.

Types of Brake Fluid
1. DOT 3
Composed of glycol-ether, DOT 3 is suitable for older vehicles or those with basic braking systems.
It has a moderate boiling point and is prone to absorbing moisture, which reduces its effectiveness over time.
2. DOT 4
This fluid is also glycol-based but includes borate esters for a higher boiling point.
It is ideal for modern vehicles and can handle higher performance demands.
3. DOT 5
Made from silicone, DOT 5 is non-hygroscopic, meaning it does not absorb water.
It is often used in military and vintage vehicles but is not compatible with ABS systems.
4. DOT 5.1
A glycol-ether-based fluid with a boiling point comparable to DOT 5.
It is designed for high-performance vehicles and is compatible with ABS systems.

Differences Between Brake Fluid Types
The main differences between brake fluid types lie in their chemical composition, boiling points, and moisture absorption capabilities.
DOT 3 and DOT 4 are glycol-based fluids that absorb moisture, requiring regular replacement to maintain braking efficiency.
DOT 5, made from silicone, is resistant to moisture but not compatible with other types.
DOT 5.1 combines high performance with compatibility for modern braking systems, including ABS.

How to Maintain Brake Fluid
Proper maintenance of brake fluid is essential for the longevity and effectiveness of your braking system. Follow these steps to ensure your brake fluid is in optimal condition:
1. Regular Inspections
Check the fluid level in the reservoir monthly. It should be between the minimum and maximum marks.
2. Timely Replacement
Replace DOT 3 and DOT 4 fluids every 1-2 years due to their hygroscopic nature.
DOT 5, which doesn’t absorb moisture, can last longer but should still be monitored.
DOT 5.1 should also be replaced every 1-2 years, especially in high-performance systems.
3. Avoid Contamination
Always use the correct brake fluid specified by your vehicle manufacturer.
Keep the reservoir cap closed tightly to prevent moisture and dirt from entering.
4. Watch for Warning Signs
Spongy brake pedals, increased stopping distance, or discolored fluid indicate it’s time to replace the brake fluid.
5. Seek Professional Assistance
During routine maintenance, have a professional check your brake fluid’s moisture content and boiling point to ensure its effectiveness. Here at Proride Motorsport Jln. Kulas, we are specialists in Brakes maintenance. Our team of technician is experienced in carrying out proper maintenance for your brake system.
