3. Ensure the length of each service hy-
draulic cylinder (1, 14) to be (207
±
2)
mm, if measured from the cylinder at-
tachment point to the axis of pin
which connects the levers (5, 9) with
the forks (3, 12), respectively, with
the piston of the working cylinder fully
drawn in.
Carry out the adjustments by means
of forks (3, 12), link bolts (6, 10) having
performed the following operations:
•
Loosen the locknuts (2, 13) by sev-
eral turns.
•
Uncotter and remove the pins (4,
11) having disconnected the forks
(3, 12) from the levers (5, 9) of the
right- and left-hand service brakes,
respectively.
•
Adjust the dimension 207
±
2 mm
by screwing the forks (3, 12) to or
from the rods of the service brake
cylinders (1, 14).
•
Lock the locknuts (2, 13), insert the
pins (4, 11) and fix them by cotter
pins.
4. Fill the hydraulic drive system with
brake fluid and bleed air from it; to do
this, proceed as follows:
•
Fill the reservoirs (17, 18) of the mas-
ter brake cylinders (16, 15) with the
“Neva-
М” brake fluid, Technical

-053-
36732629-2003, to the “Max” marks
on the reservoirs (to the level of 15
±
5
mm to the top of the reservoir). In the
process of bleeding keep the fluid
level from dropping below the “Min”
mark.
•
Latch the brake pedals (19, 20) with
the interlocking strap “A”.
•
Clean the bypass valves (7, 8) from
dust and dirt, remove the caps from
them, fit a tube onto the head of the
bypass valve of the left-hand working
