Brake Master Cylinder & 4 pots

[16v_paddy]

Has anyone changed their master cylinder to compensate for the increase in pedal travel when using 4 pots?

Has it made any noticeable improvement or impairment to how the car stops?

Is it worth doing?

Im guessing you run std brakes on the rear ?

Wonder what std master cylinders sizes are ...

[MAXIBOY]

iirc they are 20mm and others are 22mm.

rally cars ran a single master cylinder either 25mm iirc on four pots and 26mm on larger tarmac four pots..

swiss runs a 23.8 master with his brembos,

the cylinder is std 406 coupe so i supose they work well together.

whats the piston size of brembos? compared to the 35.1 mm of wilwoods?
