How do you use a turkey baster to drain your brake master cylinder and refill?

To use a turkey baster for draining and refilling your brake master cylinder, first ensure the vehicle is off and safe. Remove the master cylinder cap and use the baster to suction out the old brake fluid, being careful not to introduce any contaminants. Once drained, refill the master cylinder with fresh brake fluid to the recommended level, then securely replace the cap. Dispose of the old fluid properly, as it is hazardous waste.
