secondary connecting spring from shoe assembly.
8. Remove cups, springs, and pins from stabi-
lizer plates and remove plates.
9. Clean brake backing plate and all brake
parts.
CAUTION: To avoid the possibility of brake
"grab" or "pull" after brake service has been
performed, make certain that hands are clean
when handling brake parts and avoid handling
friction surfaces of drums and linings as much
as possible.
10. Tighten attaching bolts that hold front back-
ing plate to steering knuckle to 65 foot-pounds
torque.
11. Lubricate threads and socket of star wheel
adjuster and points of contact between brake shoe
and other brake parts with special heat resistant

pletely into pivot nut to permit installation of

NOTE: Black spring is used on right side of
car and yellow spring on left side. These
springs are not interchangeable.
Star wheel adjusters with three wide grooves on
O.D. of pivot nut (left hand threads) are installed
on right side of car and those with three narrow
grooves on O.D. of pivot nut (right hand threads)
must be installed on left side. The three narrow
grooves on the socket are for manufacturer's
identification only. Sockets are interchangeable,
left and right. Incorrect installation of star wheel
adjusters would result in automatic adjusters
loosening rather than tightening brakes. Be sure
