Rear Disc Brakes for Performance and Safety We tend to look back at the muscle car era of the 60’s and 70’s through rose-colored glasses. Everybody remembers lumpy solid lifter camshafts, big compression ratios, and blinding straight-line acceleration. But in the six decades or so that have passed since those big block-powered dinosaurs ruled the roads, we’ve gotten used to some modern performance and safety features that become conspicuous in their absence when we jump in the old Chevelle or Camaro for a trip across town. Those drum brakes that were just fine in 1969 can lead to some panic inducing near misses in modern traffic. To add some performance and peace of mind, don’t drop the bucks on a rebuild of those archaic rear drum brakes. Instead, consider a bolt-on rear disc brake conversion that won’t cost much more than a drum brake refresh, but will add some serious performance and safety to your GM midsize or ponycar.
