- Discs are self cleaning and durable in offroad conditions, no
more worn out drums from running in mud sand or silt.

#GU6102 - Long studs for 14 bolt,
many 3/4T 14 bolts will have a wheel stud that's too short when
used with the disc kit and some thicker center wheels,
especially aluminum ones, may need longer studs -
installation is shown below:
To complete the kit, the customer will need to supply the brake
rotors from a '73-'87 GM 3/4T front axle and calipers from a
'73-'87 1/2 or 3/4T front.
brake rotors have small pockets machined into the back of the
rotor for the head of the stud to seat into. If the stud head
will not fit into the rotor pocket, they can be ground to fit or
turned on a lathe to fit. Not all rotors are machined the same
so you may or may not have this problem.
works with any single wheel GM Corporate 14 bolt full float axle
with the drum secured BEHIND the wheel bearing hubs. This kit
does not work if your drums slip off from the outside or with
dual wheel axles.
Many 3/4T 14
bolts will have a wheel stud that's too short when used with the
disc kit and some thicker center wheels. Most 1-ton axles have a
longer wheel stud that's generally fine. If your studs are too short, use a 14 bolt
dually stud and you'll have plenty of thread.
applications will require an adjustable proportioning valve to
turn down the rear braking power to avoid rear brake lockup.
Swapping to a larger front caliper will help this situation
GM used a
larger piston front caliper in the heavy duty brake option or
high GVW 3/4T trucks. This
caliper bolts in just the same as the standard 1/2 and 3/4T
category you would like more information on.
