Purpose and Specifications

Valvoline Brake & Clutch Fluid DOT 4 (883429) is a premium glycol-based hydraulic fluid designed for reliable braking and clutch performance in passenger cars, trucks, and other vehicles. This 500ml bottle meets DOT 4, ISO 4925 Class 4, FMVSS 116 DOT 4, and SAE J1704 standards, ensuring it handles severe conditions like sporty or mountain driving without vapor lock.

It absorbs moisture to prevent corrosion, flows smoothly in cold starts down to -20°C for quick response, and maintains thickness up to 260°C to avoid brake fade during hard stops. Non-mineral oil formula is compatible with most rubber seals and metals in brake systems.

When to Use / Replace?

Use this fluid for all disc and drum brake systems or hydraulic clutches requiring DOT 4 performance. Replace every 2 years or 40,000 km, whichever comes first, as it naturally absorbs water over time, which lowers its boiling point and risks spongy brakes. Shelf life is 5 years unopened in a cool, dry place.

Ideal for routine maintenance, track days, or high-heat towing where standard fluids fail.

FAQ

A: Yes, mix with other glycol or borate ester DOT 4 fluids, but never with silicone or DOT 5 types to avoid system damage.

Q: What happens if brake fluid gets old?
A: It boils at lower temps, causing pedal fade and unsafe stops. Flush every 2 years for safety.

Q: Is it safe for ABS and ESP systems?
A: Yes, fully compatible with modern anti-lock brakes and stability control.
