More brake feel needed.
Looking to upgrade my brake setup which feels very `unservoed` at the min.
I have the std Sierra master cylinder and Willwood midis at the front with drums to the back.
The pedal is hard which is great but has no feel to it at all.
Do i need to upgrade/change the master cylinder and if so to what?

MC with a smaller bore will make the pedal travel further and feel softer under foot
(same/similar can be achieved by changing pedal ratio)
I went with a smaller bore MC from a Fiat (only because it was cheap...and easier than footling around with pedal ratio's)
BENDIX 132233B (19.05mm) is what I went with in the end
See http://www.locostbuilders.co.uk/viewthread.php?tid=164431

I did exactly the same as Rob with good results.
My brake setup is standard Sierra discs / drums with EBC Yellowstuff pads

Yup bolted straight up...no fettling required
Used early Sierra pov spec solid disks from a 1.6 IIRC
(so center bore is correct etc which IIRC the KA and Fiesta solids weren't)
It's a bolt up and go affair with the Sierra disks :-)
(although I did buy some shiney new braided hoses from Russbost on here as my original hoses were a little tight on full droop and full lock...not
sure if it was the angle of the oulet on the KA callipers being slightly different places/angles to the sierra venteds??)

Rob

heh i thought you had sierra uprights Rob, i have mine all apart atm so looking at a more modern lighter alternative to the old M16 calliper without
going to the expense of 4 pot alloy which i think is not needed for my application.
if i can get hold of a KA or early puma calliper i will try it out just to see

What pedal box do you have? Is there room to drill another hole closer to the pedal pivot without the push-rod catching on the edge of the m/c? A few
mm makes a lot of difference (or so my mrs tells me...).

Not sure Owelly, just wanted to put a different one on TBH as im sure that the problem
Was looking for something that is an easy fit w/o much modding etc.
Might have a look into this one that Rob has mentioned.

Early Fiesta (mk 1or2) non-servo master cylinder will do the job as well as the Fiat one. Don't know for sure but I think the bolt spacing is
the same as the Sierra.

Thats the one. I'd check new prices though 'cos they might not be that expensive and depending on how old that "old stock" is,
the seals might have gone a bit hard over time

tried a ford KA caliper on my cortina hubs and its not going to work
also they are not actually much lighter than the good old M16 caliper which surprised me

I used a nice small, light weight nissan MC on my MK, twin outputs front and rear.
You couldn't pwn your way out of a wet paper bag, with "PWN ME!!" written on it, from the "pwned take-away" which originally contained one
portion of chicken tikka pwnsala and the obligatory free pwnpadom.
