Clio 172 track car - pedal box issue

[Y8 TMP]

hi, I'm new to the Renault world. Always had track cars but this is my first Renault.

It's a Clio 172 (53 plate), cage, coilovers ect, with a Megane 225 engine and box. Came with a print out for 281bhp.

It has an aftermarket pedal box fitted- with 3 master cylinders attached. The servo from under the bonnet has been removed. I'm guessing because there would be no room for the turbo with the servo fitted?

Anyway- the pedal is absolutely solid and you have to push the pedal through the floor to get the brakes to work!! Does anyone know what I can do to improve the pedal? I want to do a track day but I'm sure the thing won't stop as the pedal is at the moment!

Any advise appreciated

Cheers

Change the brake m/c to a different bore.
Can't remember which way to go though (bigger or smaller)

You need to increase the leverage on the brake pedal/master cylinders, will mean re-designing the pedal box. I've looked at one briefly before and to get the correct ratio you basically need to start again, the main reason im still running a servo on my car until I come up with a decent layout for it.

Smaller bore will give a longer pedal but more leverage as I see it.

I actually misread that its an aftermarket pedal box, can you put a picture of it up? also find out the size of the MC's .625 & .7 are common sizes for the cylinders.
