Installation Notes

Brake fluid service should be performed by a qualified automotive technician following the vehicle manufacturer guidelines. Always relieve system pressure and clean the master cylinder reservoir thoroughly before adding or replacing brake fluid to prevent contamination. DOT 3 fluid is hygroscopic and should not be mixed with DOT 4 or DOT 5 fluids unless confirmed compatible by the vehicle manufacturer. Dispose of used brake fluid in accordance with local regulations, as it is considered a hazardous waste material.
