Parts List
General Information
• Installation of this kit should ONLY be performed by persons experienced in the
installation and proper operation of disc brake systems. Before assembling this Wilwood rear disc brake kit, double check the following to ensure a trouble free installation.
• Inspect the contents of this kit against the parts list to ensure that all components
and hardware are included.
•Make sure this is the correct kit to fit the axle housing flange, not necessarily the
rear end make. Many times aftermarket manufacturers put a different make of axle housing flange on the stock rear end housing (Figure 6). Example; Big Ford rear ends with Olds-Pontiac flanges, therefore, an Olds-Pontiac rear disc brake kit would be the correct kit to order. Also, shock clearance may be a problem. They may have to be modified and/or relocated to clear the Wilwood kit after final assembly.
• Verify your wheel clearance using Figure 2.
•Verify The Following Measurements Before Assembly.
• Bearing outside diameter. • Axle center register diameter is 2.80”, Figure 3. This kit may be supplied with
Wilwood’s removable center register adapters for rotors with larger 3.06” registers. Other rotors may have smaller 2.80” register and will not require or be supplied with register adapters.
• 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.
• The Wilwood hat utilized in this kit is drilled for 1/2” diameter wheel studs.
