FAQ

Is DOT 5.1 the correct fluid for my SRAM brakes?: Yes. SRAM hydraulic disc brakes specify DOT 5.1 fluid. Do not use mineral oil in a SRAM DOT system, as it is chemically incompatible with DOT brake system seals and will cause seal failure.

Can I mix DOT 5.1 with DOT 4 or DOT 3?: DOT 5.1 is fully backward compatible with DOT 4 and DOT 3 systems. Never mix DOT 5 (silicone-based) with 5.1 or any other DOT fluid, as they are chemically incompatible and will cause seal damage.

How often should I bleed my SRAM brakes?: SRAM recommends a full bleed every year or every 2,000 miles, whichever comes first. DOT fluid is hygroscopic (absorbs moisture), which lowers its boiling point over time. More frequent bleeding may be needed in wet conditions or with heavy brake use.

Best For

Mechanics and home wrenchers servicing any SRAM DOT hydraulic disc brake system (road or MTB) who need fresh DOT 5.1 fluid for bleeding or topping off.
