Why would my brake fluid reservoir be empty?
Why would my brake fluid reservoir be empty? Don't be surprised by finding out an almost empty reservoir after checking it days ago. It's probably due to a leak somewhere in the brake lines, calipers, or the master cylinder. To check for leaks, inspect if there are drips under the vehicle (normally along the undercarriage in a corner of the vehicle's rear). Is the brake fluid in my car empty? To my surprise the brake fluid reservoir was empty. It took about 200-250ml to fill up, I had to push the pedal a few timesand refill to bring it up...
