Purpose and Specifications

Comma DOT 4 1L Brake Fluid is a budget-friendly, high-performance synthetic fluid perfect for modern cars, trucks, and motorcycles with ABS and ESP systems. It delivers smooth, reliable braking by resisting heat buildup during hard stops, preventing brake fade in stop-and-go traffic or hilly roads. This DOT 4 fluid works safely with DOT 3 and other DOT 4 types, protects calipers and cylinders from corrosion, and ensures quick response even in cold weather down to -40°C for fast anti-skid action.

• 1L size ideal for full brake system flushes or top-ups
• Operates effectively up to 260°C+ (high boiling point prevents vapor lock)
• Meets FMVSS 116 DOT 4, SAE J1704, and ISO 4925 standards
• Shelf life: 3 years unopened in a cool, dry place

When to Use / Replace?

Use Comma DOT 4 for everyday driving, heavy braking, or performance needs where standard fluid falls short. Replace every 2 years or 40,000 km (whichever comes first) since it absorbs moisture over time, which can lower performance and cause rust. Check fluid level and color annually; dark or cloudy fluid means it's time for a change to keep brakes responsive and safe.
