Purpose and Specifications

MAXGEAR 000407 is a DOT 4 synthetic brake fluid designed to safely transfer braking force from your pedal to the wheels. This 3-liter canister meets international safety standards (FMVSS 116 DOT4, ISO 4925 Class 4, SAE J 1704) and is approved for Mazda vehicles under specification MN 120.

The fluid resists heat buildup during braking, with a dry boiling point of 245°C—meaning it stays effective even during intense driving or towing. The synthetic formula provides reliable performance across normal operating temperatures and resists moisture absorption better than conventional fluids.

When to Use / Replace?

Replace your brake fluid every 2 years or 40,000 km, whichever comes first. Brake fluid absorbs moisture from the air over time, which lowers its boiling point and reduces braking safety. Signs you need a change include soft or spongy brake pedal feel, longer stopping distances, or fluid that appears dark or cloudy.

Use this fluid immediately if:

• Your brake system has been serviced or bled
• You notice brake warning lights on your dashboard
• Your last fluid change was more than 2 years ago
• You regularly drive in hot climates or tow heavy loads

Frequently Asked Questions

Can I mix DOT 4 with other brake fluid types?
No. Never mix DOT 4 with DOT 3 or DOT 5. Always flush the system completely before switching fluid types, as mixing reduces braking performance and can damage seals.

How long does an unopened bottle last?
Unopened brake fluid typically remains usable for 3–5 years when stored in a cool, dry place away from direct sunlight. Once opened, use the fluid within 6 months to prevent moisture contamination.

Is synthetic brake fluid better than mineral-based?
Yes. Synthetic formulas like this one resist moisture absorption longer, maintain consistent performance across a wider temperature range, and provide better protection for modern brake systems with ABS and electronic stability control.
