Braking coefficients ?

[Big Bob]

Hey

am looking for some advice on brake pads have a compbrake kit and am wondering how braking coefficients work i take it the bigger the coefficient the better the stopping power but what about the weight issue as the clio doesn't weigh much i find it hard to get the temperature into the pads i have at the minuite am currently using DS2500, and was wondering if i would be better using either the ferrodo 4003 or EBC green stuff ?

Don't know much about those pads I'm afriad but the coefficient of friction between 0 and 1 dictates the amount of braking force you get for a given pad force. The greater the number the bigger the braking force.

Im not sure if braking is the same but friction coefficients are symbolised by the greek symbol mu and the higher the number the greater the friction. The range is normally from 0 to about 2.

I agree with you regarding the brakes. I have an awful time getting heat into my cars brakes and had to remove 4 pots and go back to standard pads and calipers to get any decent heat in them at all.

Anyone interested will note that the friction coefficient for the pad to disc is higher than that at the tyre to road mainly because the force of the caliper pushing the pad to the disc is higher than the force of the weight of the car pushing onto the tyres.

This means that the weakest link in the braking point is the tyre to road interface and means that you cannot reduce braking distance by fitting stronger bigger calipers to a clio (ie 4 pots) but to improve braking distance must improve the grip of the tyre.

Therefore standard calipers, discs and pads with a soft tyre will stop you more quickly than a standard tyre with 4 pots and race pads.

Yes see you guys know the biz this is all kinda what im thinking, but do i go with the DS4003 pads as they claim they are for use in formula 3 and lightweight vehicles they hava coefficient of 0.48 or do i go with cheapo EBC green stuff which have a coeffiecient of 0.55, now on paper the green stuff look like a better pad but they say they are not for track use presumably cos the will fade with heavy use well i now need something to sustain haevy use but that is for use with a light vehicle.
