Leak around brake pedals on JD 2355 MFWD

[jon686]

Fluid everywhere where the brake pedals push the pistons into the huge block that I assume to me the master cylinder. Only appears to leak when running, and marks territory when parked after shut off. Havent cleaned all the fluid off to determine exact location, but believe it is seals around the pistons that the brake pedals push on, by pistons I mean the silver rods that protrude from the large metal block mounted under the floorboard on the right side. What is this part called, what do I need to ask for to buy rebuild parts, and how hard a job is it? Do you have to drain the whole hydraulic system? Has anyone else had this leak or made this repair? Left brake works good, right needs to be pumped up to work, so I'm thinking it is the "master cylinder" but may be called something else on a tractor.

One other question- Do your tires lean in a lot when turning sharp left or right? Not sure if this is normal, reminds me of how a road grader looks when it turns.

Thanks in advance for the help.

Thanks for the reply and diagram. I will order the parts tomorrow. I'm an ex auto mechanic and a maintenance electrician in a 55 year old power plant...think I can tackle this myself? Any thing specific I neex tool wise? Do tractor brakes bleed like truck brakes?

I can't think of any special tools and I'm sure you can probably re-seal the brake valve. The trans pump refills the reservoir so if you R&R valve from trans be sure not to block that hole on reattachment. Brake bleeders are on the top of each axle housing near the trans case.
