Brake bias valve
Hi all,
I've got a new AP Racing brake master cylinder I'm fitting to replace the standard Sierra item. I was wondering if anyone knows of a
decent brake bias valve which has a single inlet (the master cylinder is only a single type) but two outlets (one for front and one for rear brakes)
which can be adjusted to alter brake bias front to rear.
The only ones I've seen are single inlet / single outlet in-line type adjusters that basically shut off flow to the calipers it's
connected to (generally fitted to the rear I presume?).
Thanks,
Carse

I maybe reaing your post incorrectly but it sounds like you are trying to use a single master cylinder to operate all the brakes which is a big no
no.
The valve you are looking for doesn't exist, a dual master cylinder would normally be sized to operate the front brakes correctly and then the
pressure reduced to the rears and a tandem setup has two mc's and a bias bar.
Sorry if I'm barking up the wrong tree
Cheers

bias
Hi
Sorry but I cannot understand why you need a bias valve
If you have that facility on the master cylinder ?.
I know the sierra had one but you should not need one with this one.
Good luck

I suspect the OP is a bit lost, I would suggest forgetting all about the AP single circuit master cylinder and use the well trodden path of
either a Fiat 124 or early VW Polo (or Golf) dual circuit tandem non-servo cylinder.
If you have 8" rear drums will are unlikely to need pressure regulating valve in the rear brake line, but with 9" rear drums
or rear discs you may need one, again the well trodden path of a Fiat Ritmo/Strada/Panda/Lada pressure regulator is the way to go.
