5 - §2 DISC BRAKES
BR
(10) Install new cotter pin in hub nut. Tighten nut
as needed to align cotter pin hole in shaft with open­
ing in nut.
(11) Install disc brake caliper. Tighten caliper
mounting bolts to 51 N-m (38 ft. lbs.) torque.
(12) Install wheel and tire assemblies and lower
vehicle.
(13) Tighten wheel lug nuts to following torque:
• 108-150 N-m (80-110 ft. lbs.) on 5 stud wheel
* 163-203 N-m (120-150 ft. lbs.) on 8 stud single
wheel
(14) Apply brakes several times to reseat brake-
shoes and caliper piston. Do not move vehicle until
firm brake pedal is obtained.
FRONT WHEEL BEARING REPLACEMENT
On models with tapered roller front wheel bear­
ings, the bearings and races can be serviced sepa­
rately when necessary. The bearing races do not
require special tools for removal. Either race can be
removed with a long tapered brass drift.
On models with unit style wheel bearings (Fig. 41),
the rotor, hub and bearing assembly are all pressed
together. However, it is only necessary to drive out
the wheel studs with a copper mallet, in order to sep­
arate the rotor, bearing and hub for replacement pur­
poses (Fig. 44).

WHEEL NUT TIGHTENING
The wheel attaching nuts should be properly tight­
ened to ensure efficient brake operation. Overtighten­
ing the nuts or tightening them in the wrong
sequence could cause distortion of the brake rotors
and drums.
Impact wrenches are not the best tools for tighten­
ing wheel nuts. A torque wrench should be used for
this purpose at all times.
The correct tightening sequence is important in
avoiding rotor and drum distortion. The correct se­
quence is in a diagonal crossing pattern as shown
(Figs 45 and 46).
Seat the wheel and install the wheel nuts finger
tight. Tighten the nuts in recommended sequence to
1/2 required torque. Then repeat the tightening se­
quence to final specified torque.
Wheel nut torques are:
• 108-150 N-m (80-110 ft. lbs.) on 5 stud wheel
• 163-203 N-m (120-150 ft. lbs.) on 8 stud single
wheel
• 176-217 N-m (130-160 ft. lbs.) on 8 stud dual
wheels
