Brake Fluid DOT 4 32 oz
Pyroil PYBF4-32 is a glycol-based DOT 4 brake fluid supplied in a 32 oz bottle. It meets OSHA standards and is formulated for both disc and drum brake systems in automotive applications.
Boiling Point 311 Degrees F
The synthetic high-temperature formula delivers a dry boiling point of 311 degrees F, providing reliable performance under normal driving heat loads. Extended heavy braking or aged fluid with absorbed moisture will reduce the effective boiling point over time.
Replaces DOT 3 Fluid
This DOT 4 fluid upgrades from lower-specification DOT 3 products by offering a higher boiling point for improved safety margins. The jump is worth it when the vehicle manufacturer specifies DOT 4 or when brake temperatures regularly exceed DOT 3 limits.

Questions about this item
Will the 32 oz bottle cover a full flush on a vehicle that still uses DOT 3 fluid?
Yes, DOT 4 fluid is backward compatible with DOT 3 systems, so the 32 oz bottle can be used for a complete flush on older vehicles originally filled with DOT 3.
How can I confirm the fluid meets the 311 Degrees F boiling point after opening the bottle?
The amber colour and synthetic high-temp formula indicate the correct specification; a professional brake-fluid tester can verify the exact boiling point once the system is bled.
Does the bottle include a pour spout or do I need a separate funnel for the brake reservoir?
The product is supplied as a standard 32 oz bottle without a built-in spout, so a clean funnel should be purchased separately for mess-free filling.
