operation of disc brake systems.
Prior to any attempt to install
this kit, please 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 exact make and

model year of your axle. This kit is designed for direct bolt-on
installation to 1994 through 2004 model year Ford Mustang
series hubs.

• Verify your wheel clearance using Figure 2.

hole pattern in the hats supplied with this kit. Axles that have
been modified with different size studs or lug patterns may
require modifications to the hat that must be performed by a
qualified machinist.

Disassembly
• Disassemble the original equipment rear brakes: Raise the

rear wheels off the ground and support the rear suspension
according to the vehicle manufacturer’s instructions.

• Remove the wheel. Loosen the four bolts from the outboard

side of the upright that holds the stock caliper mounting
bracket and lift off the bracket and stock caliper as one unit.
You may have to unbolt the stock caliper from the caliper
bracket before removal. Then slide off the rotor.

• Clean, de-grease the stock hub while removing any nicks or

burrs.
