Four-Wheel Disc Brake Install
Brake Upgrade

Ask any gathering of classic Ford enthusiasts what's the first upgrade they'd do on their project. They're liable to tell you that a disc brake conversion is at or near the top of the list. Front disc brakes are a huge improvement all by themselves, but a four-wheel disc arrangement is even better. From a standpoint of safety, and also protecting your investment, a disc brake conversion belongs high on the priority list of almost any high-performance classic Ford project. It's no secret that these conversions are possible with the many offerings out there, but they can add up quickly in cost. Now the folks at Vintage Venom offer a brilliant cost cutting solution to the problem because they offer a complete kit that allows you to install SN-95 Cobra or Bullitt four-wheel disc brakes onto your classic Mustang. The 13-inch front rotors require a 17-inch wheel and the Vintage Venom kit includes everything you need to install 17-inch Bullitt, Cobra, or Mach 1 wheels onto your vintage car, including the required longer wheel studs and spacer plates. The complete kit costs just $583 including shipping and handling.

We've seen complete sets of Cobra or Bullitt four-wheel disc-brake hardware on eBay and Craigslist for between three and five hundred dollars. The wheels are also commonly available used starting at around $200 depending on the presence or condition of tires. What this all means is that you can install a four-wheel disc brake set up on your classic Mustang for a little more than $1,000 instead of more than $2,000 and up.

Get the used rotors machined and install new pads into the calipers and you should be in business. More good news is the fact that if you don't want to fuss around with finding used rotors and calipers Vintage Venom now offers the conversion kit complete with brand-new Bullitt calipers and rotors. The cost of the all-inclusive kit is $1,557 plus $90 shipping and handling.

While the installation of the Vintage Venom kit is straightforward, you'll need to be prepared to create some new brake lines, modify parking brake connections, and be able to cut off and press on new bearings. Our project included the installation of a new '94 Cobra master cylinder, which we found locally for $79.95. You'll need to purchase new wheel bearings and seals for both rear axles and several new hard and flexible brake lines.

Vintage Venom has a very informative website to help guide you through the installation process with more than 60 pages of photographs and instructions. Follow along with the crew at KR Performance & Restorations (KRP&R) as we show you the highlights of a Vintage Venom four-wheel disc brake installation on a '68 Mustang coupe it has been preparing for some auto crossing. KRP&R was able to use calipers and rotors from one of its late-model parts cars as well as a set of '01 Bullitt Mustang wheels, keeping costs super-low.

With a little effort you too can find the calipers and rotors required for bargain basement prices from late-model owners who have upgraded, and if the wallet allows it, these parts are also available new from several OE and aftermarket sources.
