SUMMARY

The discussion centers on the impact of brake pads on a car's stopping distance, specifically comparing two vehicles, Car A and Car B. It concludes that if certain conditions are met—namely, no skidding or locking and equal total applied force—the stopping distance should remain consistent due to the linear nature of dry friction. Additionally, the conversation highlights that braking in a straight line versus at an angle does not significantly alter braking distance or time.

PREREQUISITES
  • Understanding of basic physics principles, particularly friction.
  • Knowledge of vehicle braking systems and components.
  • Familiarity with the concept of stopping distance in automotive contexts.
  • Awareness of the effects of tire conditions on braking performance.
NEXT STEPS
  • Research the physics of friction and its role in vehicle dynamics.
  • Explore the differences between various types of brake pads and their performance characteristics.
  • Learn about the impact of tire tread and condition on braking efficiency.
  • Investigate advanced braking techniques and their effects on stopping distances.
USEFUL FOR

Automotive engineers, car enthusiasts, and anyone interested in understanding the factors affecting vehicle braking performance.

TL;DR
Say: CAR A =has 4 correctly tightened brake pads.

CAR B = has 3 correctly tightened brake pads and one overly tightened brake pad (let's take front right).

The cars are the same except for the differences written above.

When a driver pushes down the brake pedal with the same force, how will the braking distance and time differ? (Car B obviously starts turning to the right, leading to change in affecting forces, even if insignificant)
My guess is that distance Car A needs to travel until it stops is longer than car B (not by much), and so it the time.

I also posted this question to reddit, if you want to check it out :

I got the answer, but unsure of it's legitimacy.

I don't think we have enough information to answer without adding in some assumptions...

1. No skidding/locking
2. Equal total applied force

If these are true, then I would think the stopping distance should be the same, since dry friction is pretty linear.

Alright, thanks. I figured out what I asked for, however it is interesting to know that breaking in a line compared to braking in an angle does not drastically affect the braking distance / time. Thanks

What do you mean "overly tightened"?
