I bought an old Case 780 2 months ago.Found out the radiator leaked and the brakes dont work.The compressor belt was missing and the mount was messed up.Got that figured out and done.The master cylinders were dry, machine sat for some time. Engi9ne is good. Refilled the master cylinders and see a drip on one wheel.Tried to bleed brakes and had to screw the bleeder all the way out to get drippage.The brake actuators at the masters are working with the air running but still no brakes. I cat pull wheel now I put some hydraulic fluid stop leak in the line thats dripping. Im going to try to adjust the brakes at the wheels.The emergency brakes not working either.Is there any way to tell if the linings are good?
