The braices on ail modeis are hydrauii-
caiiy actuated and utilize a wet type disc
controiied by a brake operating valve lo-
cated on right side of clutch housing. See
Fig. 162. Brake discs are splined to the
final drive shafts and the brake pressure
ring is fitted in inner end of final drive
housing. Except for a pedai adjustment,
no other brake adjustments are required.
BLEED AND ADJUST
152. BLEEDING* Brakes must be
bled when pedals feel spongy, pedals
bottom, or aher disconnecting or disas-
sembling any portion of the braking
To bleed brakes, start engine and
run for at least two minutes at 2000
rpm to insure that brake control valve
reservoir is filled.
NOTE: Brakes can also be bled
without engine running if necessary.
Remove right platform and fill brake
control valve reservoir by removing
filler plug (11-Fig. 163). Follow same
bleeding procedure used when engine
is running except brake valve reservoir
will need to be refilled after each fif-
teen strokes of the brake pedal.
Attach a bleeder hose (preferably
clear plastic) to brake bleed screw lo-
cated on top side of final drive housing
and place opposite end in filler hole of
rockshaft housing. Slowly depress and
release brake pedal until oil flowing
from bleedef hose is completely free of
air bubbles, then depress brake pedal
and tighten bleed screw.
Repeat bleeding operation for op-
posite side brake.
If you need more info please post back
I have access to the manual for this machine if you need more info.
Do you have dual brake valves?
If so I cant beleive both vavlers have failed or both brakes have failed I would think you have a fluid charging problem.
There should be a plug right on top of the square block valve for filling, I will try to get you a piture to make sure we are on the same page.
#11 is the plug for filling
Thank you for your last reply. have done all above next question is...
as you know my john deere is a 1975 2030, we have over come our problem it was a broken check valve.
The problem we have at the moment is our PTO shaft turns constantly while fully depressing the clutch and operating our PTO lever does not make any difference to the turning of the PTO shaft, well it does not stop...
could you advise us on the procedure to check the causes or would it be more a involved operation in the system????
Does the clutch dissengage the transmission when the tractor is moving?
Do you feel any type of resistance in the PTO lever when you moveit? Can it be moved withoput dissengaging the clutch?
Yes the clutch does dissengage the transmission when the tractor moving.
No we do not feel any type of resistance in the PTO lever when we move it...
And yes it can be moved without dissengaging the clutch....
hopefully this will help..
There are at least 3 different PTO systems for this tractor non of which I am familiar with I did find some info on them and posted in a file share in the links below.
