Bias valves

[jimbob-mcgrew]

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

ahh i see. cheers.

corsa b uses the weird pressure box valve thing, mounted near the rear beam. which has a spring attached to its lever, thats controlled by the amount of weight in the car or something. i couldnt figure it out on mine, it was useless.

ive had an ABS tigra before, that uses pretty much the same layout as the corsa B, and that had the box valve at the back, it went through the ABS pump first, before hitting the valve.

i dont like that system myself, the brakes felt horrible to me, and i had random lockups now and then when on bumpy ground, from both the front and the back, randomly, almost like the system couldnt make up its mind about what to do.
plus there operated by an external lever, and 8 out of 10 that ive seen, the levers were usualy seized, and the weight control spring was rotted away.

keep the regular nova system i think, and try look out for a narrower valve.

or if no luck, you could do what meritlover said, and fit an adjustable valve, with a thumbscrew on, and have it setup totally custom for your style of driving.

Jonesfach how much you looking for? I would prefer new 3/20 valves but I can't seem to find them unfortunately, I have searched for many hours with no luck! Thanks for all the info folks!

Just thought I would let people know that vauxhall can get the valves from Germany for about £80 a pair so if anybody is stuck thats where to go. Didn't they would be able to get them but nice surprise to find out they can
