I have a mk5 fiesta zetec s, with racing puma rear beam + disc conversion.

Running standard 253mm set up at the front at the mo!

My back end is a little twitchy under heavy braking!

I bought a 300mm conversion for the front, which i'm guessing will make matters worse!

So got a wilwood brake bias valve! I've no idea how to plumb it in! I'm no mechanic, but learn by giving it a go!!!

Can anyone give some advice, or has anyone done this before?

I'd guess i'll have to make new brake lines. 1 line to the front brakes from the master cylinder with a t section, then from the other output of the master cylinder to the rear via the bias valve inside the cabin????

Thanks for any guidance or advice!!

 

I did it and went straight back to drums.
Performance wise your pissing in the wind.
Looks is all the good for but id go with the 180s just to show off.

Just make new rear line running into the car and fit the valve where you want and just tee it off in the boot and pop one hole either side pop the lines in and connect to rear and turn the bais valve right down.
