SRAM 5.1 DOT Hydraulic Brake Fluid - 4oz

What SRAM brakes use DOT 5.1 hydraulic fluid?

SRAM 5.1 DOT Hydraulic Brake Fluid is the correct fluid for all SRAM and Avid hydraulic disc brakes that use DOT-based fluid — which includes the majority of SRAM's road and MTB brake lineup including Red, Force, Rival, Apex, Guide, Code, Level, and DB series brakes. The non-silicone DOT 5.1 formulation is engineered to maximize brake performance and longevity in Avid and SRAM systems. The key performance advantage over DOT 3 and DOT 4 fluids is a higher dry and wet boiling point, which means more heat capacity before vapor lock occurs under sustained braking on long descents or repeated hard stops — a meaningful difference on mountain stages or long alpine gravel descents. The fluid comes vacuum sealed to prevent moisture absorption before opening.

Hydraulic brake fluid absorbs moisture over time from normal use, which progressively lowers its effective boiling point. This is why periodic fluid replacement is part of proper hydraulic disc brake maintenance — a full bleed with fresh fluid restores the original boiling point margin and is typically recommended every 1 to 2 years depending on riding frequency and conditions. At 4oz, this bottle provides enough fluid for multiple bleeds. Use with the SRAM Pro DOT V2 Bleed Kit for a complete service setup. Never mix DOT fluid types and never use mineral oil in a DOT-specified brake system — the two fluid types are not compatible and will damage seals.
