Need a quick answer please

If a brake caliper exerts 1000kg on a brake pad what is the force due to the this weight?

It can't be umg because there is no g in horizontal weight.

Does g = 1

Therefore F = m

Your question does not make sense. A brake caliper cannot 'exert' 1000 kg on anything, since kilograms is a measure of mass and not force.

I have a specification for a brake caliper that states its clamping force is equal to 4136kg. I know force doesn't equal 4136 but what does clamping force mean then

Could you attach or link to the specification document?

I'd interpret it at the equivalent of 4136 kg, that is 4136 kilogram-force or kiloponds. So the force would be 4136/g or about 422 Newtons.

Thank you for your fast respones

In which case, I'd agree with alxm's interpretation,

Bloody engineers :tongue2:

does this mean the static frictional force is independent of vehicle mass?

 

[russ_watters]

The force between the brake pads and rotors is not a function of gravity. It is generated hydraulically. If that's the static friction you are talking about, then you are correct, it is not a function of vehicle mass. Judging by the question you asked yesterday, however, I'm guessing you now asking about tires and are still confused about this...

That would be 4136*g or 40,500 Newtons.

[revolution200]

That can't be true. I have a car stopping with kinetic friction as u*m*g = 0.7 * 1000 * 9.8 = 6860N

I thought static (ABS) is more effective than kinetic

Static coefficient * force = 0.5 * 422 = 211N

This can't be right

oh, cheers

 

[revolution200]

can anybody give me an example of average clamping forces for vehicles
