All the brake lines look fine.

Do you think it has had a calliper change to Vitara brakes then?

If it has, are they on square, I mean the calliper isn't twisting in any way is it? Are these callipers on sliders? Do they move freely?

All moves freely. If I just crack the banjo undone to release pressure everything frees up..
The strange thing is no matter where I relieve the pressure ( banjo, top of flexi, master cylinder ) it frees of. The only thing I can think of is the 6 way valve thing.

It sounds like a master cylinder issue then.

Can you get if off strip, clean and change seals as needed, or even just swap it for another?

You mean this valve?

Has your other zook not got one? Also have you tried completely draining the brakes and refilling? Might be some crap stuck in a pipe

I put the other master cylinder on and still no joy and it works perfect on the other one.
I would have thought that by now I have changed the fluid about 5 times with all the bleeding.
The other valve is on my other sj but it ends on ebay tomorrow so don't want to mess about with it incase it sells.

Not sure how the 6 way valve could cause this problem :er:
I only say this because my valve does one front, one rear from either feed from the master cylinder.
It is just your front brakes sticking on ?

Have a look at your valve plumbing as they are not all the same, some only have a 5 way valve and one side does the front brakes alone and the other side the rear brakes.

That's the same as mine. I agree with what you say but it is the only thing I have not changed and I don't know how they work. Is it unheard of for these to fail??? Thanks for the help.

Never heard of one failing.
Just wondering if it's possible for the servo to stick on applying force after you have braked :er: :er:

Strange one this !!

I thought the portioning valve was the gadget near the fuel filter?
There's three ways of doing things:

The right way,
The wrong way
And my way, which is like the wrong way but faster.
