Is 4 disc brakes really necessary for 1.6L and below Sedan?

[Watwheels]

In today's automotive pantheon, it's not uncommon to find four-wheel disc brakes as standard equipment on medium-priced, non performance-oriented models. The majority of new vehicles, however, continue to utilize a front-disc/rear-drum brake setup. What does this say about the current state of braking systems? Are these manufacturers sacrificing vehicle safety in order to save a few bucks by installing disc brakes on only the front wheels?

 

While a "yes" answer would certainly be great for increasing Town Hall traffic, the truth is that today's disc/drum setups are completely adequate for the majority of new cars. Remember that both disc and drum brake design has been vastly improved in the last 20 years. In fact, the current rear drum brake systems on today's cars would provide better stopping performance then the front disc setups of the '70s. And today's front disc brakes are truly exceptional in terms of stopping power. Combined with the fact that between 60 and 90 percent of a vehicle's stopping power comes from the front wheels, it's clear that a well-designed, modern drum brake is all that's required for most rear wheel brake duty.

 

High performance cars like the Viper, 911 and Corvette can justify a four-wheel disc brake system, especially if their owners participate in some form of sanctioned racing activity on the weekends. The rest of us get more of a benefit from the lower cost of drum brakes. Expecting every vehicle built today to come with four-wheel disc brakes would require an across-the-board increase in purchase price, and that could stop new car buyers much quicker than any brake system.

dics brake is the toyota's most favour, almost all toyota models except Wish regless Engine Capacity are all disc brake, but Nissan is another end, you almost can't find any 1.6L and below Nissan models c/w all disc brake, even 2.0L Sylphy still is using rear drum brake

I wonder is it necessary that 1.6L and below family Sedan equip all disc brake

 

 

Why not? Disc brakes is always recommended.

my car coming to 3 years liao ... received inspection notice letter ... stock stock stock all the way :)

 

usually changing ther rear disc callipers is more troublesome due to some having the integrate parking brake.

 

well like most safety things, it is not about the 99% of the time when you don't need the extra stopping power, but rather that in that 1% situation when that over spec'ed system is there to save your skin.

 

anyway not all rear drums / ABS / EDB systems are created equal.
