Purpose and Specifications

MOTUL 105836 DOT 5.1 Brake Fluid is a premium 100% synthetic fluid in a 1-liter bottle, compatible with DOT 3, DOT 4, and DOT 5.1 systems. It excels in anti-lock braking systems (ABS) and electronic stability programs, delivering smooth, reliable performance by resisting heat buildup that causes brake fade.

Key benefits include a dry boiling point of 270°C (518°F) to stay effective during hard stops, and a wet boiling point of 185°C (365°F) for long-lasting protection even when moisture creeps in. This means firmer pedal feel, quicker response, and safer braking in daily drives or track days.

When to Use / Replace?

Use MOTUL DOT 5.1 for modern vehicles with ABS, ESP, or high-performance brakes needing superior heat resistance over standard DOT 4 or DOT 3 fluids. Ideal for cars, motorcycles, and clutches under demanding conditions.

• Replace every 2 years or 40,000 km to prevent moisture absorption that lowers boiling point and risks fade.
• Flush if brakes feel spongy, during pad changes, or after track use.
• Shelf life up to 5 years when unopened; operates reliably from -40°C to over 270°C.
