what is the approx brake pedal force that a person applies while braking on the brake pedal?
vinay ks said:i want to know for disc brakes. 100 lbs is a large force! can a person apply that much of force while he is seated on the pedal? i want to know how a person who is about 130 to 150 lbs apply that amount force??
Kozy said:Go and put some bathroom scales against the wall in a corridor, sit on against the opposite wall and push on the scales with your right foot. That'll give you some idea of what is reasonable. I can assure you, 100lbs is not 'normal' braking in a modern passenger car!
I challenege anyone to generate 560lbs too. Maybe an F1 driver in an F1 car capable of braking at 3g (additive force from decelleration), but not an average driver in a normal road vehicle. Not a chance.
Brake pedal force is the amount of pressure required to push the brake pedal down and engage the brakes of a vehicle.
Brake pedal force can be measured using a dynamometer, which is a device that measures the amount of force applied to the pedal. It can also be calculated by measuring the force applied to the brake pads and dividing by the pedal ratio.
The main factors that affect brake pedal force are the type of brake system, the size and weight of the vehicle, and the condition of the brake components such as the brake pads and rotors. The pedal ratio, which is the length of the pedal arm compared to the length of the master cylinder push rod, also plays a role in determining the required force.
Approximating brake pedal force is important for designing and testing brake systems in vehicles. It allows engineers to determine the optimal pedal ratio and brake system components to provide efficient and safe braking performance. It also helps in identifying potential issues with the brake system that may require adjustments.
Brake pedal force can be reduced by using a power brake booster, which uses engine vacuum to assist in applying the brakes. This reduces the amount of force required to push the pedal. Other methods include using a larger pedal ratio or upgrading to more efficient brake components such as larger brake pads or ventilated rotors.
