Master Power Brakes Disc Brake Kit - Install Front Disc Brakes
Master Power Brakes’ new assembled disc brake kit offers yet another way to upgrade your front brakes
There’s no question that replacing original drum brakes with disc brakes is one of the best safety upgrades you can make to a vintage Mustang. Today, the options include modern calipers and rotors, which improve braking performance over the factory’s optional front disc brakes. Taking it up a notch is the availability of rear disc brakes, which were never offered on ’65-’73 Mustangs from the factory.
While most front disc brake conversions are offered as kits with rotors and calipers for installation on the existing spindles, Master Power Brakes’ latest product for ’65-’73 Mustangs comes fully assembled on brand-new spindles with late-model Mustang two-piston calipers and 11-inch slotted rotors. Master Power offers two kits: DB1520B for ’64½-’66 Mustangs and DB1524B for ’67-’73 Mustangs. For the ’65-’66 kits, the spindles are aftermarket Granada-style, which bolt right up to the Mustang control arms and tie rod.
While Master Power’s latest disc brake kit eliminates the need to assemble the calipers and rotors, including the messy job of packing grease into the wheel bearings, the swap does involve the somewhat laborious job of removing the existing spindles from the upper ball joint, lower ball joint, and tie rod. Of course, for many of our experienced readers with a well-equipped tool box, that’s a piece of cake.
Also note that, as with most performance-based front disc brakes, larger wheels may be required to clear the calipers. Master Power recommends 15-inch or larger. After Merv Rego and Levi Kelly tackled the swap on Mark Houlahan’s ’66 Mustang hardtop at Classic Creations of Central Florida, we performed a test-fit with Mark’s factory 14-inch Styled Steel wheels. They wouldn’t even mount on the hub. Next we tried a standard 14-inch steel wheel, which fit over the hub but didn’t clear the caliper. Most aftermarket 15-inch and larger wheels should fit without issues. As with any brake swap that involves larger rotors and calipers, be sure to consider wheel fitment.
