There are several possible reasons why your brakes may not be stopping well, including worn brake pads, low brake fluid, air in the brake lines, or a malfunctioning brake system component. It is important to have your brakes inspected by a professional mechanic to determine the exact cause and ensure your safety on the road.
Front brakes have significantly more stopping power than rear brakes.
BRAKES
It depends on the road conditions, as well the state of your brakes.
Larger brakes = shorter stopping distance.
Certainly, all four wheel brakes are used in normal stopping. However, the lions share of the stopping power is from the front brakes, yes.
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.
There are three main types of bike brakes: rim brakes, disc brakes, and drum brakes. Rim brakes are common on traditional bikes and are lightweight, but may wear down rims over time. Disc brakes offer better stopping power and perform well in wet conditions, but are heavier and more expensive. Drum brakes are low maintenance and durable, but may not provide as much stopping power as disc brakes. Overall, disc brakes are considered to offer the best combination of performance and durability.
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.
V-brakes and cantilever brakes are two types of bicycle brakes. V-brakes are mounted on the frame and use a cable to squeeze the brake pads against the rim. Cantilever brakes are mounted on the fork and frame and use a cable to pull the brake arms together, which then squeeze the brake pads against the rim. V-brakes are generally considered to have better stopping power and are more effective for stopping quickly.
Apply the brakes hard and steer out of danger.
No. Your stopping distance will almost double.
In general they SHORTEN your stopping distance as they can apply more force to the breaks.
