Maroon belly 7000 brakes

The left brake pedal is a bit stiff to push, not hard but not the usual, right side is fine, and both brakes work how they should. Decided I was goingto take the brake covers off and fluid started to come out of the bottom bolt hole on both sides so I put both bolts back in. There shouldn’t be any fluid in there right? What would be the cause and solution of such? Is that why the left pedal is stiff? Hydraulic fluid is full, dipstick behind the cab shows that is slightly low. Any help is appreciated

Cab mounts are good, plenty of space between linkage and bottom side of cab floor

As for the fluid coming out of the bolt hole, no there shouldn't be any fluid at that level, but I do believe those holes are through-drilled into the final drive section of the rear casting.  The final drives should only have oil up to the level plug, which is a little under the centerline of the axle on the side of the housing behind the lift cylinders.  If they are overfilled, there are only 2 ways oil can get in there outside of being overfilled through the breather by operator mistake.  1) The bearing caps on the axles have come off.  2) The pinion seals are leaking by.  You can remove the top cover and use a mirror or really contort yourself to see if the bearing caps are on or not.  If off, you will need to remove the rear end housing to seal them and reinstall them.  If those are in place, then you have leaking pinion seals.  Either one of these would cause the oil from the differential/PTO reduction gear case to drain over to the final drives.  You can also check by draining the final drives down to the level plug (or all the way) and seeing if oil starts coming over from the differential housing well past the amount it would take to get under the pinion bearings.  If the bearing caps are off, it will drain out that housing much more quickly and down to a much lower level than leaking pinion seals.

I disconnected the linkage and the pedal feels the same, I looked at all the springs I could and they looked ok and I couldn’t see the cab touching the linkage anywhere

Keep the dipstick underneath the SMV sign FULL  !!!!
