Master cylinder leaking
Got a good stiff pedal, I don't think there is air in the system. At this point I'll try anything. I was wondering if the bore was to large for the system...
My mentor taught me the difference between "thinking" you got all the air out,, and "knowing" you got all the air out,, is that test.... lol
On my first brake job as apprentice,, while bleeding, he asked me if I knew how to tell if all the air was out.. He took me to 3 vehicles parked on the lot and pumped the brakes, had me remove the cover and watch, very little fluid movement on release.. We went back and did test to car I was working on,.. lol,, had about a 3 inch fountain,, and I "knew".....
That was the final test on every brake job..
We'd find air in cars that never lost fluid...
I've passed that on to all my apprentices, and everyone who worked for me..
hope it helps
