Chances are you've never thought about your hydraulic brakes being anything else -- unless you're in love with classic cars. When we say classic, though, forget those muscle cars and hotrods and think older. And then go a little older. To find a car without hydraulic brakes, you'll need to find a pre-1940s era vehicle -- a real antique.
When cars were first made, they used just rear brakes. They weren't powerful or heavy enough to require a second set of brakes, and most people thought that braking on the front wheels could cause the car to flip over [source: Joseph]. But generally, by the mid-1920s, cars became more powerful, and the two-wheel braking system wasn't cutting it. Once people realized they wouldn't automatically crash with front-wheel brakes, the four-wheel drum brake system became popular.
Unfortunately, these early four-wheel systems were very complex, with lots of carefully constructed hardware to properly proportion out the force between the front and rear brakes. This system was replaced, but it wasn't until the 1940s that hydraulic brakes became relatively standard on cars [source: Joseph]. Most people now convert their classic cars from mechanical brakes to hydraulic brakes to get better braking efficiency. Don't expect to have the stop-on-a-dime power of a brand new Jag or Mercedes, though. Your revamped braking efficiency still might be only 65 percent [source: Waller].
Should you choose to perform a hydraulic brake conversion, the Internet is a great resource for do-it-yourself kits for purchase. Such kits can be simpler no modification kits, all the way up to complex kits that reroute lines and cost several thousand dollars. No matter how you choose to perform a hydraulic brake conversion, be sure to do it thoroughly and carefully -- brakes are probably the most important safety feature on your car!
