Lude Generation

In my plans I need to push a greater volume of brake fluid whilst retaining similar to OEM pedal travel.

I was thinking that Legend bits would be the automatic upgrades. What year Legends would do the job? Is the piston in the master cylinder any larger? Anyone know?

OR

What other bits could I use instead?


Edit - Update read this on 15/16" MC from non-ABS Ludes Vs the 1" MC http://www.ludegeneration.co.uk/chassis ... t4731.html

you dont need a larger piston, you need the piston to travel further with the same pedal movement so a change in leaverage would be achieved, this would mean a different master would be needed is it possible to use a slimmer piston in the original cylinder giving more travel, then some how adjust the axis point of the peddle if you see what im saying. but a bolt on alt would be easyer.

A larger piston would move more fluid per cm of pedal travel, side-stepping the need to find a way of increasing the OEM MC's cm movement/displacement ratio of fluid. I have been reading up and it seems that the Prelude's 25.4mm (1") piston is the largest that Honda do. Even the NSX uses a 1" MC. The only other method is to swap out for a purpose built MC, but thats too much £££.

Littlefeller I like the idea of using leverage to get around this whole issue. So I would need to move the arm of the MC further down the brake pedal? In what way would I need a new MC? Simply to find one with a longer arm to the MC? I wonder If I could fab up an extension? Im not sure how this would affect the angle of the MC though

ive seen civic boys using an s2000 MC with a spacer...something to do with the reservoir attached to the MC and not separate on the shock tower

this looks interesting

if you move the ram further down the pedal (the axis for the pedal movement is at the top and above the mc) then the travel of the pedal would be reduced in pedal travel vs piston travel, but the overall pressure exerted on the fluid would be lower so you would need to brake harder, although the point of lock would also be bigger giving greater feel.
if you move it upwards, closer to the pedal axis then the travel would be greater for the pedal vs piston, but the pressure exerted on the fluid would be greater alowing less pressure to be placed on the pedal. some race drivers find the extra travel usefull in finding the point of brake lock

oh yeh almost forgot, if your reading this and thinking uuumm i may be able to do something like this on my daily, be carefull, i think the brake pedal travel is checked on mot

is not that easy just oversize master cylinder or change leaver on it, you have more components in whole brake system so you need count on that as well before you start modifying brake system.

I did not think of this. I suppose that fact is usefull when trying to set up a brake bias / proportioning valve. There is a wider range in which to set the bias.

Can you expand on this? So I understand what you exaclty mean?

The lude MC is like that, although the 4G and 5G are different;

4G


5G


I dont yet know the exact differences in the two Lude MC's, they have the same 1" piston but the 5G one is clearly different. Maybe it is slightly more efficient/better to compensate for the marginal increased weight of the 5th gen. I have always found my 5G to brake better than my 4G even though they have the same pads, discs, hoses, and fluid Maybe the difference in the MC is the reason. I doubt that my brake stopper on my 5G is the reason for better braking.

pad, rotors, calipers and master cylinder/s all work together, considering weight, speed and road/track.

every component work together with another component in your brake system so you need considering what affect one component will have on another one.

Yup I get all that. I'm planning a big brake kit, hence the questions on master cylinders
