Our 6-lug disc brake kit contains all you'll need to put
modern discs on your stock 1/2 ton spindles, and uses your stock hub. The
1-1/4" thick, 12" rotor uses a GM full-floating caliper. The 8"
single diaphragm booster master cylinder and proportioning valve mounts
in the stock location. We recommend that you upgrade the stock ball bearings
to tapered roller bearings when using this kit. Some stock wheels may rub
the calipe, it may be necessary to use a spacer. May not work with some
stock wheels. Also, 1947-50 trucks may need to drill out lower spindle hole
from 7/16" to 1/2". Note: Frame mount brake boosters may require
#CP9424 transmission mount.
