I believe she is a 1/2 ton with a low ratio transmission. But my question regards the brake master cylinder. I have had issues with the pedal going down to the floor, but only when driving not sitting still in the yard. I have bled them and overhauled a wheel cylinder. I replaced the master over a year ago. I noticed the fluid in the master will shoot out if the cap is removed and press the brake. It even bubbles out around the cap (there is no gasket or "O" ring on the cap.
Is this normal for the master to shoot oil around inside when pressing the brake pedal?
Thanks,
Glenn
