Ford 555 brakes

So I took my 555 out today, pushed the brakes to release the parking brakes and it felt like something popped and now no brakes and the peddle goes to the floor. Any help would be appreciated
 
I can't see the linkage from here. Follow the mechanical linkage between the brake pedals and the point where the rods enter the rear axle trumpet housings on either side. look for missing pins, broken pieces, etc.
 
There are two sets of brakes on that tractor one inside each of the axle trumpets. There should also be two brake pedals next to each other with an interlock on the left pedal to connect them together so they work as one. Each pedal is only linked to the brakes inside one side of the rear axle or the other. So when you say that you followed the linkage to "where it enters the axle", it sounds like you only followed the linkage from one pedal back to one side of the axle. What about the other side?

If you try to drive the tractor does it feel like the brakes are being applied? If you pull the brake pedals up by hand, does that free up the brakes?

Each brake pedal should have it's own return spring and if your brake pedals are linked together, it may just be that you've been running with one return spring for a while, and that spring finally gave way.
 
Sir
The pedals return to the up position once I push on
them but when I do apply the brakes the pedals go
to the floor and does not stop the tractor at all,
hopefully this clears it up a little
 

If everything is intact outside the rear axle, sounds like time to do some wrenching on the axle. CNH has a parts look up on their web site, so you might want to go there first to see what's in the axle.
 
Ouch.... sounds like one of the pins came loose inside on the actuator ball ramp linkage. PARK it until you open it up. You don't want sloshable parts finding their way to the planetary...

Pull the axle housings. I'm assuming that this thing has manual lever operated brakes and not hydraulic brakes. It would possibly depend on what generation machine it is...

Rod
 
They would definitely be manual brakes...
Just to clarify.... are you saying it has NO brakes on either side?

Rod
 
I know you said you checked the linkage.... but I think you should check it again. If it was just one brake affected then I'd say it was probably an internal problem even though that is odd. Given that you say BOTH are affected... that to me would be almost unheard of. I'm just wondering if one of the mounting points for a linkage fulcrum has come loose or something. That might allow you to see some movement in the linkage but not apply any real braking force. But if you are truly seeing a full steady range of movement on the brake actuator rods at the axle housing on BOTH side.... then I pity you. As Bern said, those axles are a pain in the arse to remove, heavy, etc. It's not a bad job on a tractor but on those hoes... it really sucks.
I think Rick is the one to give you a tutorial on that subject...

Rod
 
I appreciate the assistance and if it is worse case scenario is it possible for me to use the machine around our ranch without doing any internal damage?
 
I agree with Rod. The likelihood of both brakes completely failing at the same time is extremely rare, unless someone really stomped HARD on both brake pedals at the same time.
 
If there's something broken internally I would not move it. You run a considerable risk of parts gravitating into either the outer planetary reduction gears or the differential itself. If you think you have a problem now.......

Rod
 
Wherever it sits. Get a friend and work the linkage while you watch and also closely inspect any mounting points for the linkage in the cab, the actuator rods, the cross shaft in the center housing, etc.
Depending on how desperate a situation it's sitting in might move it slowly to a location more convenient...

Rod
 
Yes, but those brakes are very basic anyway. If the problem is internal I'd suspect it will be missing or broken pins in the actuator linkage which will be quite obvious.

More likely one side was already NFG and he managed to break the other side when he hit the pedal. I was always amazed at all the stuff that was messed up on some of the cars I wrenched on, and got the 'It didn't do that before' when they wanted me to fix it for free....
