3. Deaeration of the brakes of the rear wheels 

 
Parking brake adjustment  

MHS16N046

 

 

Before adjustment of the hand brake secure the tractor against movement with wedges and release the hand 
brake. There is a vertical position of the lever (A). Set the length of the pull rod (B = 130 mm); the length is 
measured from the centre of the pins according to the figure. Adjust the pull rod (B) for the right brake on the 
other side as well. Adjust the pull rod (C) with the solid end of bowden so that its length from the centre of the 
pin to the bracket is (C = 198 mm). Finely adjust the full overstrain or clearance of the hand brake using the 
bowden adjusting nut (D) so that the clearance between the pin of the lever (A) and pull rod (B) is 1 mm. Lift 
up both rear wheels of the tractor, secure the lever of the hand brake to the fifth claw of the ratchet wheel 
and try to turn one wheel; the wheels must not turn. If the wheels are turning, check adjustment of the pull 
rods and finely adjust with the screw (D), if appropriate. When the hand brake is released, both wheels must 
rotate freely. Asymmetry of braking effects must not be higher than 20%.

Use the following procedure: 
1. Check the amount of the brake fluid in the equalizing 
vessel and add the missing amount of a new liquid to the 
max. amount. 
2. Remove the rubber cap, install the hose on the 
deaeration screw (1) of the brake cylinder and immerse its 
other end to the bottom of the transparent vessel partly 
filled with the brake fluid (2). The deaeration screw must 
be permanently under pressure to prevent air penetration 
through its threads. During this operation place the vessel 
at least 300 mm above the deaeration screw. 
3. Release the deaeration screw by 1/4 revolution max. 
4. Press down the pedal on the deaerated side fully and 
tighten the deaeration screw. 
5. Release the brake pedal and repeat the procedure until 
no air bubbles come out of hose.6. Repeat the procedure 
on the other side.
