CPP 64-67 Nova Stock Spindle Front Disc Brake Conversion kit install
This page describes the installation of Classic Performance Products' 64-67 stock spindle front disc brake conversion kit. Aside from the obvious improvement of a disc setup over the stock drum brakes, this kit has two major benefits. First the kit is designed to work with the stock 5-lug (64-67) front spindles. No need to modify the bracket mounting boss as with the 68-74 retrofit approach. Second, this kit is designed to keep the track width the same as it was originally. Again, the 68-74 retrofit approach falls short, as that will push the front wheels out about 1/2" per side. That can cause your tires to rub if you are tight for space.

10/6 - Just getting started with this install...boxes arrived earlier today, haven't had time to do much more than open the boxes and see what's inside. MUCH more info to come later, but thought folks would like to see the new shiny bits ASAP. Some quick photos of what arrived (pretty raw, haven't sorted through these yet, some are dups to avoid flash glare...)
boxes!
This is what's in the kit
rotor/hub - one piece
back of rotor/hub
brake pad ASA-350-FF 7070A
6110
new hoses!
caliper brackets
hardware kit...spindle nuts,
bearings, bracket bolts, dust cover
This is not part of the kit,
but I got the new CPP master cylinder with built-in proportioning valve
It's tough to take good pictures
of shiny stuff! Very nicely polished...
Brake line set (also not
part of kit) that I'll use as a starting point. This will need to be modified
to fit the new master cylinder.
