An Inexpensive Upgrade to Serious Stopping Power In the 60’s and early 70’s, drum brakes were generally considered to be just fine for safely halting a muscle car in traffic. Disc brakes were a luxurious, extra-cost option that often only ended up under performance packages like the Super Sport or Z/28. But as time has marched on, we’ve grown accustomed to our late models with electronically assisted disc brakes on all four corners that will stop on a dime. Meanwhile, a trip across town in that old drum brake equipped Chevelle, Nova, or Camaro is an exercise in constant vigilance and planning ahead for a panic stop. It’s almost enough to take the fun out of the drive. It doesn’t take much to drastically improve on the 19th century design of those drum brakes, especially in the front. A simple, inexpensive front disc brake upgrade using OE-style components can make a night and day difference when compared to those old, fading drums. That’s where this kit fits in. While there are bigger, more trick brake kits out there, the Speedway Motors ’64-’74 GM Car Front Disc Brake Kits comes with everything you need to ditch the drums and add a disc kit to keep your GM A/F/X body car safe in modern traffic at a price that doesn’t break the piggy bank.
