Calculating Braking Forces of a Disc and Drum Brake .

Click For Summary
SUMMARY

This discussion focuses on calculating the braking forces and braking distance when converting a car's rear drum brakes to disc brakes. The user has the weight at each rear wheel and utilizes DAC to determine maximum speed and maximum deceleration. Key formulas for these calculations are referenced from the theory on longitudinal acceleration and braking. Understanding these principles is essential for effective brake system modifications.

PREREQUISITES
  • Understanding of basic physics principles related to force and acceleration
  • Familiarity with braking system components, specifically disc and drum brakes
  • Knowledge of vehicle dynamics and weight distribution
  • Experience with data acquisition systems (DAC) for performance metrics
NEXT STEPS
  • Research the formulas for calculating braking force and braking distance
  • Explore the theory of longitudinal acceleration in automotive contexts
  • Learn about the differences in performance characteristics between disc and drum brakes
  • Investigate the impact of weight distribution on braking efficiency
USEFUL FOR

Automotive engineers, mechanics, and car enthusiasts involved in brake system upgrades or performance tuning will benefit from this discussion.

Hello ,
I have to change a car's rear drums to discs . I have the weight at each of the rear wheels . Using DAC I know the max speed and max Decelerations sustained by the car . What are the basic formulae used to calculate the braking forces and the braking distance .
 
Engineering news on Phys.org
Look at the theory at the bottom of this page (Theory »» Longitudinal acceleration »» Braking).
 
Thank You , it was helpful .
