Where do you add add brake fluid to a 1994 BMW 740?

To add brake fluid to a 1994 BMW 740, locate the brake fluid reservoir, which is typically found near the back of the engine bay, on the driver's side. The reservoir is usually a translucent plastic container with a cap labeled for brake fluid. Ensure the vehicle is on a level surface, remove the cap, and add the appropriate brake fluid (usually DOT 4) until it reaches the recommended level marked on the reservoir. Always check for any leaks and ensure the cap is securely replaced after adding fluid.
