Bike fell in grass while working on it now front brake doesn't hold pressure
I have a 2023 Kawasaki Z400 I was working on it in the grass when it fell over the handlebars got slightly misaligned, but I was able to fix that but now the front brake lever doesn't hold pressure, if I do rapid squeezes, it will work but is jolting and loses pressure when held down or pulled in slowly. I have tried bleeding the brakes and no air has come out my only other thought could be the master cylinder was damaged in the fall. Any help is greatly appreciated!
