Hi Robert, you will have to bleed the brakes. There is a bleeder screw on top of each rear axle, looks like a grease zerk.

Require clean bucket and 1/4 or 5/16 inch clear tubing that will fit over bleed screw nipple.
To bleed the brakes run the tractor until the Hytran hydraulic fluid reaches operating temperature.
Run engine at fast idle 1400-1600 RPM, block rear wheels.
1)With tubing connected to nipple on bleed screw and other end in clean bucket, loosen bleed screw and let hydraulic fluid drain until air bubble free, then close bleed screw. Repeat on other brake. Do not pump brakes while bleeding.

Top up hydraulic fluid with fluid caught in bucket, make sure transmission fluid level is full or over full. Also check for leaks by bottom of dash and along top of transmission cover. Brake lines run from under battery box along top of transmission to rear axles.
May have to repeat bleeding and if bleeding only lasts a few days then repost and I will give a procedure to diagnose if it is leaking seals in brake piston.

Good Luck
JimB
