ok I have a 2950 with hyd brakes, the brake "master" cyl sits under the rt floor and the pedal attaches, if I press the pedal lightly on the rt brake , the pedal seeps down to the bottom,if I hit the pedal hard it stays hard and stays fully up, its only when I depress the rt pedal softly that it drops to the bottm , the left pedal is fine works as it should,,

im guessing the cyl on the master s rt side is seeping, if so can I get a rebuild kit
 
yes brakes were bled and it may help for a little while then the pedal does the same thing on the rt side ,press easy goes to the bottom , press hard and it stays
 
Possibly check valve.
Sometimes piston ring will act that way.
Cap the line to be sure.
 
If it acts the same it may just need cleaned out good,,seals are available for them as well as check valves,,a lot of time it's the equalizer valve located under the housing,, they are a 1/4" ball and spring,, I have pulled them ,,cleaned them and put a little extra "stretch" in the spring and go back together and all would be good. Number 4 in the circle is the check valve,,the lower circle is one of the equalizer valves. The equalizer valves are to keep even pressure on both brakes when they are both applied,, the check valve gets tilted a bit to let oil into the pressure piston then seats as the pedal is applied,,it is not a good design,, and the only pressure you get is dictated by the foot pressure applied to the pedal,,they are not power brakes..

ok best place to get valve or parts for this if I need any, im used to rebuilding master cyl, wheel cyl etc
im old school
 
The check valves are Deere only:#4 is AL69179, #1 is a plug R35286 ,#11 is a spring T21816 , two gaskets not shown are L63387
 
ok silly question, di I just bolt this cylinder unit back on the side of the tractor? how or where does it fill with hydraulic fluid? I see the small hole what's best way to bleed system I know the two bleeders on back but the cylinder has to have fluid
 
I took the line loose from the master and the same re action, it has some sort of bypass , I have taken apart cleaned and stretched spring and now I put it on, how does it fill with fliud to bleed?
