Motul Dot 3 & 4 Brake Fluid

Motul DOT 3 & 4 Brake Fluid – 100% Synthetic Hydraulic Brake & Clutch Fluid

Motul DOT 3 & 4 Brake Fluid is a 100% synthetic polyglycol-based fluid designed for hydraulic brake and clutch systems requiring DOT 3 or DOT 4 specification fluid.

Suitable for a wide range of road, performance and everyday vehicles, it offers reliable braking performance, good thermal resistance and compatibility with common non-silicone brake fluid types.

With a dry boiling point of 245°C and wet boiling point of 158°C, Motul DOT 3 & 4 is a dependable choice for routine servicing, brake fluid replacement and clutch hydraulic maintenance.

DOT 3 & DOT 4 Compatibility

Motul DOT 3 & 4 is designed for vehicles where the manufacturer specifies either DOT 3 or DOT 4 brake fluid.

This makes it suitable for a broad range of hydraulic brake and clutch systems.

Always check the vehicle manufacturer's specification before use.

High Boiling Point Performance

Brake fluid is exposed to significant heat, particularly during repeated braking.

As brake fluid temperature rises, its resistance to boiling becomes increasingly important.

Motul DOT 3 & 4 offers:

• Dry boiling point: 245°C / 473°F
• Wet boiling point: 158°C / 316°F

The dry boiling point refers to fresh fluid, while the wet boiling point reflects performance after the fluid has absorbed moisture over time.

Why Brake Fluid Boiling Point Matters

Brake fluid operates under hydraulic pressure to transfer pedal force to the braking system.

If the fluid reaches its boiling point, vapour can form within the hydraulic system.

Unlike liquid brake fluid, vapour can compress, which may result in:

• Increased pedal travel
• Softer pedal feel
• Reduced braking consistency

Using the correct high-quality fluid and replacing it at suitable service intervals helps maintain reliable braking performance.

Suitable for Brake & Clutch Systems

Motul DOT 3 & 4 can be used in compatible hydraulic:

• Brake systems
• Clutch systems

This makes it a useful fluid for general vehicle servicing as well as brake system maintenance.

Mixable with Compatible Brake Fluids

Motul DOT 3 & 4 can be mixed with:

• DOT 3
• DOT 4
• DOT 5.1 non-silicone brake fluid

It should only be used where these specifications are suitable for the vehicle.

Silicone-based DOT 5 fluid is a different formulation and should not be mixed with conventional polyglycol brake fluids.

Ideal for Routine Servicing

Brake fluid gradually absorbs moisture from the atmosphere over time.

As moisture content increases, the fluid's boiling point can decrease.

Regular brake fluid replacement helps maintain:

• Consistent pedal feel
• Reliable hydraulic performance
• Suitable boiling resistance
• Brake system reliability

Motul DOT 3 & 4 is well suited to routine brake fluid changes and scheduled maintenance.

Road & Performance Use

Motul DOT 3 & 4 is a strong option for:

• Everyday road cars
• Performance road cars
• Brake system servicing
• Clutch hydraulic servicing
• Vehicles requiring DOT 3 fluid
• Vehicles requiring DOT 4 fluid

For dedicated track or motorsport applications where substantially higher fluid temperatures are expected, a more specialised high-temperature racing brake fluid may be more appropriate.

Standards

Motul DOT 3 & 4 meets:

• FMVSS 116 DOT 4
• FMVSS 116 DOT 3
• SAE J1703

Important Information

Always confirm the correct brake fluid specification for your vehicle before use.

Brake fluid is safety critical and should be handled carefully.

Avoid contamination with water, oil or other incompatible fluids.

Once opened, the container should be kept tightly sealed because brake fluid is hygroscopic and absorbs moisture from the atmosphere.
