ABS removal

No I get it was asked hundreds times but since Photobucket fucked up loads of info is lost.
When taking abs pump off I suppose to swap proportion valve for non abs (single piston) one. I highly doubt that I'll find one so I'm wondering what happen if I'll leave twin piston one?
Another idea I've had, since most of braking force goes on front brakes can I just bypass proportion valve for front brakes and just fit t piece.
Or could I put small adjustable bias valve for rears?
Last one how are brake circuit split on Pulsar is it one for front one rear or is diagonally?

Thanks Mike

I've put pulsar valve on my Almera and just blocked off the extra holes with blanked brake pipe Mike, almera works fine, why not get a sunny or an Almera one and just swap??? Will that not work

Should have a sunny valve here on my shell still??

Is your Almera non abs mate? Tbh I don't care what I'll use there (might be even Renault valve) as long as it'll do the job

It is abs actually but should have a valve on my old sunny which I don't think was abs as its a shit spec lol

Will check tomo night for you Mike

Thanks a lot Tom!!
