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 rear axle disc brake kit, double check the following items to ensure a
trouble-free installation.
•Make sure this is the correct kit to fit the axle housing flange, not necessarily the
rear end make. Many times after market manufacturers put a different make of
axle housing flange on the stock rear end housing (see Figure 6, next page).
Example; Big Ford rear ends with Olds-Pontiac flanges, therefore, an
Olds-Pontiac rear disc brake kit would be the correct kit to order.
•Verify your wheel clearance using figure 2.
•Inspect the package contents against the parts list to ensure that all
components and hardware are included.
•Verify The Following Measurements Before Assembly.
• Bearing outside diameter.
• Axle housing flange mounting pattern to pattern in bracket.
• Stud pattern on axle flange to stud pattern in hat.
• Dimension from wheel side of axle flange to wheel side of axle housing
flange (see Figure 6, lower right hand corner). This dimension is critical
to ensure proper alignment of the rotor to the caliper, and should match
offset given in the kit description.
• Verify that the wheel axle stud size is 0.50” diameter. The Wilwood hats
utilized in these kits are drilled for 0.50” diameter wheel studs.
• Maximum axle flange diameter must be no larger than 6.47” w/.050” x 45° chamfer (Figure 3).
Disassembly Instructions:
•Disassemble the original equipment rear brakes:
Raise the rear wheels off the ground. Support the rear suspension by placing jack stands under
the rear axle or vehicle frame. The vehicle’s weight must be on jack stands. The vehicle must
not be supported by a car jack or hoist.
Completely disassemble the stock brake system down to the bare axle. Degrease and remove
any dings or burrs on the housing flange as well as the axle flange which may interfere with the
brake assembly. Assemble the axle into the rear end housing.
