The front brakes on any vehicle do most of the stopping. When you apply the brakes the weight shifts to the front of the vehicle. For this reason the front brakes are needed more than the rear. Try stopping a vehicle with just the hand brake which applies only the rear brakes.
yes they do most of the stopping
Front brakes provide about 70% of stopping force. Disc brakes have an advantage over drum brakes in that they can provide more stopping force without overheating (and thus loosing their stopping efficiency). I believe drum brake units are less costly to manufacture than disc brakes, so using them on the rear also saves manufacturing costs.
most all newer vehicles have disc brakes, they are engineered for size and weight of the vehicle, they produce more stopping power than drum brakes
There should be more braking power to the front wheels for two reasons. As the brake is applied there is a change in the balance of weight distribution on all four tires caused by the vehicle pitching down on the front. This places more weight on the front tires. If there was more braking taking place on the rear tires than on the front, there would become an oversteer condition and the back of the vehicle would skid out.
There are several reasons, the main one relates to the weight transfer that occurs when applying the brakes, making the front wheel brakes work harder, thus needing more effective stopping power and more efficient cooling. It is basically a matter of cost. Drum brakes are cheaper to produce than disc brakes thus saving the manufacture money. Another reason is that on a vehicle without independent wheel suspension, as in a pick up truck, disc brakes are a little more difficult to design and produce. It all boils down to manufacturing costs. They will use drum brakes whenever they can.
In general they SHORTEN your stopping distance as they can apply more force to the breaks.
power brakes are more powerful
Braking power transmitted to the front wheel is high compare to that of rear wheel normally(60:40 or 70:30) in motor cycle.Disc brakes which has high magnitude of braking power compare to that of drum brakes are used in motor cycles to absorb the more braking power.
It varies go greatly there is no real answer. Depends on your driving habits and so much more. I have known a Corolla to need front brakes at 20,000 miles and another went 75,000 miles, Keep in mind that the front brakes do 70% of the stopping and the replacement interval is directly proportional to that.
Foot brakes are used to stop a car. In an emergency however both the foot and hand brakes can be used to stop a car.
If you have rear drum brakes, you have to adjust your rear brake shoes. That will also give you a better pedal and more stopping power.
