Price List
•Installation of this kit should ONLY be performed by individuals experienced in
the installation and proper 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.
•Verify the year and model of your spindle. This kit is designed for direct bolt-on
installation to 1998 through 2002 model year production spindles that were
originally equipped with twin piston calipers. This kit will not fit 1993 through
1997 production year spindles originally equipped with single piston
floating mount calipers. The correct spindles are identified by casting
numbers 18023021 and 18023022. 1993 through 1997 model year vehicles
may be updated with the later model spindle to accommodate installation of
this kit.
•Verify your wheel clearance using Figure 2.
•Verify that the factory hub and stud pattern matches the stud hole pattern in the
hats supplied with this kit. Hubs 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.
•WARNING: Brake pads included in this kit are intended for high temperature
race use only. Extended use at low temperature can cause accelerated rotor
and pad wear. Please see the associated components list on the last page of
this data sheet for alternative brake pad compounds for other uses.
Disassembly
•Disassemble the original equipment front brakes and support the front suspension according to the vehicle 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. Save the stock caliper mounting bracket bolts, they will be utilized during reassembly, then slide off the stock hat and rotor
assembly. Optional: Removal of the dust face plate to facilitate easy removal of additional parts and/or for aesthetic purposes if you
will be running spoked wheels and would like to see the slotted rotor.
•Clean and de-grease the spindles as well as the stock caliper bracket bolts. Remove all nicks or burrs on the spindle snout and threads.
