Master cylinder activation

[Big Daddy]

I was wondering if anyone has used cables instead of mounting the cylinders directly to the pedal via a mechanical linkage.

Be careful with cables...you need alot of force t actuate a master cylinder. Also, cables tend to fray if they are put in tight radius's, limiting their percived benefit.

Agreed I was just wondering if any one had done it before and if so where there any safty issues from the judge's stand point. I have some really nice cables in mind http://fsae.com/groupee_common/emoticons/icon_wink.gif

As a judge I would have no problem with remote mounted master cylinders operated by cables, as long as it was done safely and correctly.

There would be two cables incase one broke so you would not lose braking. Thanks Pat.

Two cables is the correct way to go, but would there be any way for the driver to know that one of the cables is broken? I would imagine that it would be dangerous to drive the car with one of the cables broken because then you have no backup. Of course if one cable broke, then it also signals a high likelihood of the other one breaking, unless it was a manufacturing flaw in the first cable, and not a design problem.

I would be most worried about lost motion. I know that at least in our footbox, we don't have a lot of room, and having even a little lost motion can really throw off your braking setup.

I know from the prevoius 2 Australian competitions that Tokyo Denki ran with a twin cable setup. The master cylinders were placed behind the dash, and the cables ran from the pedal to them. I dont know where the bias bar was. I am unaware of any problems suffered from them.

The promary reason to un them in this way was to make the car shorter.
