TIP: BE CAREFUL THAT ALL HYDRAULIC COMPONENTS ARE KEPT CLEAN AND FREE
OF DEBRIS INSIDE AND OUT. REMEMBER: DIRT IS THE ENEMY OF HYDRAULIC
SYSTEMS. SSBC WILL NOT BE RESPONSIBLE FOR SYSTEM FAILURES DUE TO AN
UNCLEAN INSTALLATION.
1. Raise the vehicle until the tires and wheels clear the floor and support the vehicle on jack
stands. Make sure parking brake is in the off position. Remove the tire and wheel
assemblies from the drum.
2. Remove drum brake assembly as follows:
a)
Remove brake drums.
b) Disconnect parking brake cable from drum assembly.
c) Disconnect rigid brake lines at rear axle junction block.
BE CAREFUL NOT TO GET BRAKE FLUID ON THE PAINT. IT CAN CAUSE
SEVERE DAMAGE.
3. Remove axles and backing plates as follows:
a)
Remove differential cover, a drain pan will be necessary.
b) Working through the opening of the case, remove the side gear piston shaft lock bolt.
c) Push the side gear pinion shaft (pin) out.
d) Push the axle shafts inward and remove the "C" locks from the inner end of the axle
shafts.
e) Remove axle shafts.
f) Remove backing plate and shoes from axle flange as an assembly, after removing
anchor bolt and lower cap screws; discard bolts and nuts.
4. Caliper mounting brackets (left and right side are different):
a)
Attach tie bracket to bottom of each axle flange (tube side), using two 1/4"-28 socket
head (allen) screws and lock washers (6mm-1 x 25mm for late models) both types
supplied. (Plate also acts as a spacer between axle flange and caliper mounting
bracket.) Mount with radial cut-out facing up.
b) Install caliper mounting bracket from inboard side of axle housing making sure that
spacer/thrust plug (pressed onto bracket) enter large hole in flange bracket from
inboard side with caliper mounting holes at the rear. Secure bracket to flange using
special 5/8" x 2" cap screw, lock washers and nut (inboard) and two 7/16" cap screws
at the bottom which thread into tie bracket.
5. Splash shields (optional).
a)
No splash shields are provided due to the size of the caliper mounting brackets which
effectively protect the rotor from road debris. Nonetheless, in the event that splash
shields are desired, they may be ordered from SSBC at an extra cost and secured with
two 1/4-20x1/2" screws and lock washers per side. Torque to 5 ft/lbs.
