Been working on my 480F and ended up tearing out the floor to get at the brake lines. One on the left side was rusted and leaking. The floor was also in rough shape so i cut out all the old rusted spots and replaced with new metal and painted. Now back to the brake lines. I got the old one out along with the Rubber hose going to the Slave cylinder. I did away with the rubber hose and replaced it with a steel line all the way back. My question is 1, do you need that hose for a reason or is running a steel line all the way back ok? Question 2 is, will the brakes pump up while the tractor is not running or do you have to run the tractor to bleed the brakes?
