Nigel Riches Posted October 28, 2019 Share Posted October 28, 2019 Being lazy here, does anyone on these pages know the lever ratio of a standard Caterham brake pedal? Just doing a bit of fettling and one thing lead to another, as they do.Any assistance gratefully received.Regards. Nigel. Link to comment Share on other sites More sharing options...
Area Representative Richard Price Posted October 28, 2019 Area Representative Share Posted October 28, 2019 Nigel,I've got a drawing that I did when working out dimensions for a dual master cylinder setup, which works out at 3.25:1.However, having modified several brake pedals, I know that I've seen several different patterns of pedal.Why do you want to know?

Nigel Riches Posted October 29, 2019 Author Share Posted October 29, 2019 Thanks Richard, the one I have measured this afternoon is 3.75:1, admittedly this is a modified pedal for shorty pants drivers like me, and the standard one from the 1982 car is 3.09:1, approx.I am trying to sort out a long pedal travel, and understand longer arc of movement for the same M/C piston rod travel, but there are other things which could cause this, as I have recently had all the wheel cylinders and calipers off, and apart to fit new seals, the M/C was replaced, and also had new seals, as it was an old unit covered liberally in anti corrosion fluid, it worked.The pedal always was a bit long, but not as much as now, and the man from the ministry has to give it the tick, or it's not on the road, don't thinks it's going to meet his requirements as it is.I had a new one piece pedal made to meet the regulations, that used the same dimensions as the longer pedal mentioned above. I still feel I can get a higher pedal with some more fettling, bleeding, adjusting etc.Nigel. Link to comment Share on other sites More sharing options...
