9+ DOT 3 vs DOT 4: Brake Fluid Differences You Need

DOT 3 and DOT 4 are both glycol-ether based hydraulic fluids employed in automotive braking systems. The primary distinction lies in their boiling points. DOT 4 fluid possesses a higher dry and wet boiling point compared to DOT 3. The dry boiling point refers to the temperature at which the fluid boils in a new, uncontaminated state, while the wet boiling point indicates the boiling point after the fluid has absorbed a certain amount of moisture, which inevitably occurs over time through exposure to the atmosphere. This difference in boiling points dictates their suitability for various applications.

The higher boiling point of DOT 4 offers enhanced resistance to vapor lock, a dangerous condition where vapor bubbles form in the brake lines due to excessive heat, diminishing braking performance. This increased thermal stability is particularly beneficial in vehicles subjected to more demanding braking conditions, such as those driven aggressively, used for towing, or equipped with anti-lock braking systems (ABS). Historically, the development of DOT 4 was driven by the need for improved braking performance in vehicles with higher performance requirements.
