6. When adjusted correctly, the lever travel should correspond
to 4–6 clicks of the pawl, and when controlling the travel the force
to the lever must equal to 600+10N (60+10 kgf). After adjusting
lever 3 must be lowered and lifted rear wheels should be turned
with hands.
It is forbidden
to check the parking brake system while moving.
It should be done only on a slope.
Drive-line parking brake, affecting the driving system
(Fig. 9.28).
Clean the brake shoes from dust and dirt and sand them, if they
get greasy. Replace greasy linings or keep them in clean gasoline
for 20–30 min and grind them with sand paper or wire brush.
Replace the linings in case of their excessive wear (the rivets are
sunk less than 0.5 mm).If the linings are glued, replace worn brake
shoes, if the linings wear to a thickness of less than 1.5 mm.Grind
the linings on new shoes so that their diameter is 0.3–0.4 mm less
than the brake drum diameter.
Despite labyrinth seal of the release and adjusting mecha-
nisms, they gradually collect dirt, therefore dismantle and clean
the mechanisms (especially the release mechanism), adding new
grease (Litol-24). Do not let the grease contact the drum and the
linings.
Adjust the brake
when the brake lever travel gets more than
half of its maximum travel and when braking effect is insufficient.
WARNING! Use a pit or a hoist for adjustment.
Adjust the air gaps between the shoes and the drums
as follows:
1. Shift the transfer case lever into neutral position.
2. Lower parking brake lever 1 (Fig. 9.28) into its extreme
position.
