dual wilwood 0.625 master cylinders on my car

 

cheers!

 

 

Interesting, I am running 2x 0.75's on my brakes and they work just fine...I do have Wilwood Powerlites front and rear, should that make any difference

 

 

I have the std handbrake calipers at the back on my kit, I think it does make a difference! The piston area will be quite a bit smaller than yours..

I had the 2 0.75 and the pedal felt good but there was no pressure at the calipers I have now got a .625 for the front and .7 for the rear now the pedal is a little spongy but the brakes are there just they won't stop you in a hurry tho I have got to do something with them I am scared of driving it incase I run in the back of someone I am at a loss as to what to do next I am thinking about binning the braided hoses and putting copper pipes it would be nice if all the kits had the same brakes on them would make eliminating stuff a lot less hassle

did you try switching the master cylinders around?

0.7 for the front

0.625 for the rear brakes

 

by the way, my car had zcars flexis all round (the blue ones). No copper pipes...

It is properly bled isn't it? Spongy brakes makes it sound like there is still air in the system. You should get a solid pedal once fully bled and thus shouldn't feel spongy.

Alright Alex yeah I have sent 2 bottles of fluid through it I toke it to a lad who has a couple of rally cars today and he said the pedal feels fine good travel and solid at the bottom so I am stumped now I am going to have a mess about with the bias bar but I am not sure if that's an issue because neither front or rear will lock up

I've got the big brake kit on my car with Clio? rear callipers. The brakes were awful even though it passed the MOT brake test with the polymatrix pads that came with the kit . I swapped the front pads to FERODO DS2500 and instantly they felt better, the car now stands on its nose. My master cylinder is 0.75
