model year Ford Mustang GT.
•Verify the hat pattern in this kit matches the lug pattern of the vehicle’s axle hub.

Disassembly Instructions
•Disassemble the original equipment rear brakes:
Raise the rear wheels off the ground and support the suspension according to
the vehicle manufacturer’s instructions.
Remove the wheel, caliper, and rotor. Do not disconnect the brake line.
Remove all nicks or burrs on the axle flange face, registration diameter, and
caliper mount lugs on the upright that may interfere with the installation of the
new components.
Clean and de-grease the axle flange and upright.
Assembly Instructions (numbers in parenthesis refer to the parts list and Figure 1 on the preceding page):
• The caliper mount bracket (1) should initially be installed with clean, dry threads on the mounting bolts. Orient the bracket as shown
in Figure 1 and install using bolts (2) washers (3) and nuts (4). Temporarily tighten the mounting bolts. NOTE: The bracket must fit
squarely against the mounting points on the axle hub. Inspect for interference from casting irregularities, machining ridges, burrs, etc.
Remove bolts one at a time, apply red Loctite® 271 to threads, and torque nuts to 70 ft-lb.
