Gimme a Brake!
By Jok Nicholson
f you have read the previous articles on our
Back-2-Basics '72 Vega, you know it ended up
running in the low 10-second range. That is
about a full second quicker than I thought it
would run with such a small hydraulic cam. Isky
Racing Cams was right; they said I would be
impressed with the power a .515" lift hydraulic
cam can produce.
Now that we have it running
almost 130 mph, the stock Vega front brakes
and the rear drum brakes on the Dana 60 just
don't cut it for stopping. Keeping with the
budget plan, I shopped all over to get the best
price and the best stopping power. I ended up
working with Aerospace Components, Inc out of
St. Petersburg, FL. They also offer a front
brake kit, but right now the budget isn't there
for that upgrade. The technical sales rep told
me I would be surprised at how much difference
the rear disc brakes would make. I trust he
is right, but for now I will just cover the
initial installation. Final brake line plumbing
and a master cylinder are still on order and
I will add that to this series later in the
is the Aerospace Components rear disc brake
kit for my Dana 60. As you can see, the machine
work is excellent and all hardware was included.
I started off by taking the drum brakes off the rear end housing and pulling the axles out. Now is a good time to replace the axle retaining bolts if they are still the original ones. I replaced mine last winter so I am okay there. If your axle bearings have been in there for about a decade, now is the time to have a couple fresh ones pressed on. I also replaced those last winter so they are good.
is the "stuff" I removed. The previous 11-inch
drum brakes served their purpose, but at 130
mph I felt it was time to upgrade the brakes.
The nice part was the total cost of the kit
was only $445. At this point you should consider
replacing the rear axle bearings, drive studs
and axle bearing retaining bolts if it has been
several seasons since you last replaced them.
