Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I'm currently working on the design of an e-caliper and I need to this effect to determine the linear force at which the pads have to be pressed against the disc to slow down a car swiftly.

The result of my calculations is that the pad of asingle frontbrake has to be pushed with a linear force of 35.51 kN (!) in order to bring to a halt (deceleration force of 1.2 G) a relatively weighty car (gross weight of 2353 kg) driving on the freeway at 130 km/h.

Is that a realistic value or is there something I've done completely wrong in my calculations ? It seems to be very high considering it's for a single braking unit.

I'd appreciate if you can take a gander at the attached picture and tell me if my calculations are right. (my apologies for the English typos in the text, it's just a draft and needs to be refined anyway).

Thanks in advance.

Guillaume.
