Formulary Braking force

Braking force in disc and drum brakes

In this case, the braking force is to be determined on the effective diameter. This can be assumed as being the center-point of the brake block (disc-brake) or that of the brake-pad (drum-brake). It depends on the static friction (blocking wheel) or the dynamic friction (rolling wheel) between the pad/block and the drum/disc. In the formula it is assumed, that one tension force for each pad/block, thus two tension forces are effective. Otherwise the factor '2' in the formula must be accordingly altered.

Braking force on the non-blocking wheel:

 FU = 2 · FS · µG

 µG =
           2 · FS

 FS =
            2 · µG

Here you can check your calculation:
