Wilwood Dynapro Radial Front Drag Brake Kit - Manual (Page 3)

General Information and Disassembly Instructions
Parts List
•Installation of this kit should ONLY be performed by persons
experienced in the installation and proper operation of disc brake
systems. Before assembling the Wilwood front disc brake kit, double
check the following items to ensure a trouble-free installation.
•Make sure this is the correct kit to match the exact make and model
year of the vehicles spindle (i.e., hats for a 1980 Mustang spindle will
not fit a 1997 Mustang spindle).
•Verify the factory hub stud pattern matches the brake hat in this kit.
•Verify your wheel clearance using Figure 2.
•Inspect the package contents against the parts list to ensure that all
components and hardware are included.
Disassembly Instructions
•Disassemble the original equipment front brakes:
Raise the front wheels off the ground and support the front
suspension according to the vehicles manufacturer’s instructions.
Remove the wheel. Remove the two bolts from the backside of
the spindle that hold the stock caliper mounting bracket and lift off
the bracket and stock caliper as one unit. If space is a problem,
you may have to unbolt the stock caliper from the caliper bracket
before removal. Slide off the stock hat and rotor assembly.
•Clean and de-grease the spindles. Remove all nicks or burrs on the
spindle snout and threads.
