Bias valves
Hi wondering if anyone can tell me what cars had bias valves screwed into the brake master cylinder like 3/20 3/25 etc that would be suitable for my nova that has rear disc conversion it has 3/35 but it's a death trap! Rears just lock up
if anyone where I can get them that would be great thanks
Apparently some saloons have them, early mk2 astras with discs. I did look and it's not easy to tell best bet is get to a scrap yard and check old gm cars. I ended up running a wilwood
Mk2 Astra has them but they don't fit novas master cylinder. Had to change mine to one from a corsa/tigra
this ecat24 page might be of some use. [click]
a quick google search of them shows that they are about £75 each, so a bias valve, or a decent scrapyard find is in order.
I'm not sure what master cylinder is on it tbh but it's dangerous the way it is.
thats them on that ecat page. Gonna struggle to find them by the looks off it
Just plumb an axle load valve off a corsa or Peugeot/citroen into the car and have a thumbscrew to adjust it.
sorry for butting in, but what do the valve numbers mean ?
3/20
3/25
3/35
some sort of pressure ratio im guessing ?
What do the corsa Sri s use. Is the proportioning done in the abs unit?
I'm not sure what the corsa use but certainly the abs obviously stops if from locking up.
Jimbob-mcgrew I'm not sure what the first number means but I know the smaller the second number the more restrictive it is. Mine is a 3/35 just now but it's applying to much pressure to the rear
Are you after some 3/25s ? Second hand ones-be better with new ones really though I would think.Originally Posted by mutchy_Nova
Might have some if you are struggling to find some up by you.
