When it comes to discussing the history of Mopar, the first thing that everyone remembers and talks about is the fact that Mopar knew how to go quick and win races. The cars were often in the winner's circle, and were unsurpassed in their ability to accelerate. But, what no one seems to remember is the sometimes less-than-adequate braking capabilities of these cars. Sure, in stock form, a '70 Road Runner was aptly capable of stopping while driving through town--in 1970, but in today's traffic...
There are a lot of reasons you should consider when it comes to upgrading to disc brakes. The main reason is safety. For starters, drum brakes are easily damaged by heat and moisture. Get them wet or hot, and they will not work--period. Even when they're in good working order, they offer less-than-optimal stopping power, especially in today's traffic conditions. Chrysler actually introduced standard disc brakes on the front of their vehicles sometime in the 1950s, but it wasn't until the mid-1960s, when power-assisted units, which made disc brakes easier to operate, hit the market. Some modern vehicles still come with drum brakes on rear wheels. Rear drum brakes are cheaper to produce than disc brakes, and since a vehicle's front brakes actually do 70 percent of the work, rear brake performance can be sacrificed for cost.
Since drum brakes do have their limiting factors, and adding front disc brakes to your car is definitely an upgrade in safety and performance, is an upgrade to rear disc brakes worth doing on your car? This is a question that only you can answer for yourself. Some guys feel that rear drum brakes are more than sufficient for stopping their cars, and it's true that a good working drum brake system on the rear of a car can work properly during normal driving conditions--if you have front disc brakes. If you have drum brakes on all four corners, just think back to the last time you panic-braked when some idiot pulled out in front of you, and tell me that an upgrade isn't worth it.
It goes without saying that you can't install rear disc brakes on your car if the front has drums on it. Well, you could but when you hit the brakes, your rear tires will lock up before the front ones even start to slow down. But if a car equipped with front disc brakes and rear drum brakes is sufficient, why upgrade to rear disc brakes? For starters, the front discs can only do so much. Have you ever noticed that your rear drum shoes last much longer than the front shoes/pads? We've been told that by adding rear disc brakes to your car, you can effectively add as much as 30 percent more braking force to your braking system. This means you stop a lot quicker, which could come in handy when that idiot pulls out in front of you.
But, you might be worried that adding a rear disc-brake kit to your car is going to be too expensive, and granted, you will have to shell out a few hundred dollars for a kit that works on your car. But, how much would the bodywork be if you actually ran into the aforementioned idiot?
