1963 Corvette: Braking Zone

We’re betting that a safety upgrade won’t hurt the value or appeal of our 1963 Corvette one bit.

When restoring a rare and expensive automobile, should it be upgraded? And if so, how, and with what?

The value of a 1963 Corvette is in its originality, or at least in its original appearance. But that means skinny reproduction tires, heavy and slow manual steering and drum brakes all around. So, what do you do?

It comes down to use and personal preferences, which means we need to ask ourselves a few simple-but-key questions.

Questions. Questions. Do I want to feel safe in my classic antique car? Am I building this car for me or for show judges?

Do I actually want to drive the car to more than just Sunday shows and feel safe about it? There are differing philosophies about this, but my feeling is that I can’t enjoy the car if it’s crashed because of crummy old hardware or outdated engineering. So, upgrades for safety make sense and really don’t detract from the car as long as they’re out of sight.

Keeping the original parts in a box is a good thing, too, which might sweeten the pot when it comes time to sell the vehicle.

The next question is who the car is being built for? Show judges or yourself?

I’ve never been a fan of spending hard-earned money on cars to please other people. If they like it, that’s cool. If not, hey, that’s OK, too. It’s my money and my car and I build what I like. If others have an opinion about what I ‘should’ do, then they can pay for it or do it to their own car.


Considerable time was spent painting all the bare-metal parts so that they would stay looking new as long as possible. In all the excitement of installation, this is often overlooked, which is shortsighted and will lead to unsightly rust in no time flat.


Still, there are others who want the trophies.

If that means no upgrades of any kind to win the restored class at the show, then so be it. That’s their choice. Chances are that such a trophy hound would trailer his or her vehicle to shows anyway, so the upgrades would never be necessary.


Parts that look stock but are safer than the originals are key to maintaining the visual appeal of the 1963 Corvette

So, in the interest of driving safety without visually messing up the ’63 Corvette, I kept the upgrades to stock-appearing parts that are bolt-ons. As such, I decided to change to power front disc brakes from drums.


Changing to disc brakes on a classic Corvette might be easier than the decision to make the swap in the first place. There are new brackets and bolts to mount the calipers.


There are plenty of conversion kits to do this, but there are few things to keep in mind:

  1. For retaining the stock wheels, the new brakes will actually have to fit within them. Measure, measure, measure.
  2. When changing the master cylinder and adding a power-brake booster, try to get parts that look right. Brightly coloured, oddly shaped and too-modern parts under the hood of the otherwise stock-appearing ’63 Corvette would be a visual detraction. That’s less of an issue with the hidden parts, such as the brake rotors and calipers, but it’s best to be aware of it.
  3. Often, changing to disc brakes will affect the track width, usually pushing the wheels farther apart. If clearances are tight, this could pose a problem. Also something to measure, measure, measure.
  4. Although most brake kits just bolt right in, the parts are usually bare metal and will need to be properly finished before final assembly so they don’t turn all rusty and crusty.
  5. A proportioning valve will be needed to tune the rear brake bias to match the front. Failing to do this could mean new brakes that are worse than the old brakes. No one wants that.


I purchased a stock-looking package from a vendor on Ebay for about $1,100 that included a new master cylinder and power booster as well as a proportioning valve, which is plumbed in line with rear brakes and has an adjustment knob. The kit came with everything needed, including brake lines to hook up the calipers.

Of note is that this particular package pushed the front wheels out about an inch. Since I was using narrow tires and the fender lip was above the edge of the tire, this didn’t seem to pose a problem.

The most difficult part of the operation, really, was trying to decide how to finish parts that never came with the car so that they actually look like they came with the car.

There was no hope for a match when it came to upgrading to a ‘street and slalom’ suspension, however. That’s a story I’ll save for next time.


A disc-brake package was selected that, when installed, looks like it came from the factory, even though this 1963 Corvette came with drum brakes.

Meanwhile back at the body shop, the Corvette has even more unexpected corrosion and some very shady patchwork. Check out the giant hole at the base of the windshield. That’s on both sides, by the way.
