Pedal Travel With 4 Pots

[Adnic69 0]

I have looked but can't find anything relating to four pot calipers and pedal travel. I have just bled the alcons I bought from Stew205 on here. I dont think i have any air in the system. The pedal travel is huge, goes a long way down. This is going to be slightly biased as I am use to the Elise brakes.

People that have fitted four pots, have you changed the master cylinder?

For what it's worth, Alan's 205 with 406 23mm and Wilwood 4-pots had no more travel than the standard brake setup

 

If you're keeping with the standard MC then you will have longer travel, no question.

Are they a pain to change?

Nope, straight swap.

 

Might need to adjust the length of the actuating rod.

 

You need a non ABS one, 4 port.

M/C are easy to change - providing the nuts haven't seized. You have to match the M/C to the piston size though. Just saying "4 pots" is little use.

Your pedal must feel mushy feel as if it's actually connected to nothing.

You will need to swap to a non ABS 4 port M/C, as suggested already.

Firstly, how large are the caliper pistons?

I'm using Hi - Spec 4 pots with 39mm pistons. I have a 24.5mm M/C (the largest they do) and the pedal is solid. It's far better than standard. So, if you have pistons upto 41mm or so, you sholud find a good progreesive pedal.

M/C size is dependent on your caliper piston size. I use a 23.8mm 405 non-abs M/C on my hi-spec 4 post and the pedal feel and preogressive nature of the brakes is phenominal

I made a mistake up there. I use a 23.8mm M/C. A 24.5mm item does not exist.
