The Wilwood SRP brake rotors are directional, due to
the angle of the cooling vents and slots, so it’s important
to orient them properly. The flush side of the rotor mounts
against the rotor adapter. The rotors feature Wilwood’s Black
Electro Coat finish.

The kit comes with a new keyed washer for the outer
wheel bearing. It slides into place and then we install our
original spindle nut, tightening it until there is no slack.

Once we’ve designated the left rotor from the right, we
can attach the rotor to the aluminum rotor adapter
supplied with the kit. Wilwood also supplies the hardware,
and suggests applying Loctite 271 to the threads before tight-
ening them to 25 ft-lb.22
If the hole doesn’t line up for the cotter pin, you can
tighten the nut a little more without running the risk of
wheel bearing damage. Then, install a new cotter pin.18
Next, we attach the rotor and
adapter to the hub assembly, mak-
ing sure that the rotor adapter is pushing
the rotor away from the wheel mounting
flange. These also get the Loctite treat-
ment and we tightened them to 45 ft-lb.

Using the palm method, we pack
the outer wheel bearings. The
grease is standard “disc brake grease”
available at all parts stores. It’s cheap
and it will take you years to go through
a tub of it.20
The hub and rotor assembly is
ready to slide onto the spindle.
We weighed the drums versus the disc
brake setup. The complete drum assem-
bly weighed 32 pounds per side and
the Wilwood disc brakes weigh in at 15
pounds per side.40 VETTE 19.07
