The one I did I used a hydraulic brake kit from a Chinese pit bike, worked perfectly. Only Issue I had was I had to fit the caliper on the underside of the disc and this put it close to the ground and exposed it to grass clippings in a very harsh condition. I did think if I did another one I might try one of the cable operated pushbike type, might be easier than running the brake lines
I have a small quad bike here and that has front discs and those kits are fairly cheap to buy from places like Blygo Bit of a job to mount them or it might be easier to pick up a quad bike and fit the front end to the mower. Always more than one way to skin a cat if you can put the time into it and you might end up with suspension on the front as well
