Wilwood Dynapro Low-Profile Rear Parking Brake Kit - Manual (Page 3)

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 5). 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 housing flange mounting pattern to pattern in bracket.
• Stud pattern on axle flange to stud pattern in hat.
• Axle center register diameter is 2.80”, Figure 3. This kit uses Wilwood’s
removable center register adapters. Rotors can either be centered on the
axle register, i.e. register-centric or centered on the wheel studs, i.e. stud-
centric.
Due to variations in wheel stud final diameters, register-centric
centering can be a more accurate method of centering the rotor to the axle.
Wilwood offers various diameter adapters for purchase in addition to the ones
supplied in this kit, see Table 1.
• Dimension from wheel side of axle flange to wheel side of axle housing flange (see Figure 5, 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. NOTE: Some OEM axles have 7/16” (0.44”) wheel axle
studs. It is recommended that you upgrade to 1/2” studs. Dependent on the type of axle, this may be a simple stud change, or
may require the services of a machine shop to perform.
• Maximum axle flange diameter must be no larger than 6.61” w/.050” x 45° chamfer, Figure 3.
