Hi to everybody... I would buy the adjustable bias valve, to increase the efficency of the rear wheels, (removing the original and not adjustable pressure-sensitive valvles screwed directly into the rear brake outlet ports of the master cylinder). But the adjustable bias valve have a cost, and now I have no money, and I am a tuner... so I think that I can take a load sensitive valve (it is mounted on the rear axle of the felicia, but It can be found in other car too).

So my question are:

1) Can I use the load sensitive valve instead of the bias valve? (removing the original 2 not adjustable valve screwed into master cylinder, and using the load sensitive valve mounting it near the handbrake e modify it to stay in correct position in base of my need)

2) How I can test the load sensitive valve (naturally i have one but I have no idea if it work)?

To test it you'd need a brake cylinder (to provide pressure) and two pressure gauges (high range for braking pressures) - one on the inlet, one on the outlet.

as darren says really no way of checking without a gauge, but why not fit it and try, also you could fit estate rear wheel cylinders which are 22mm instead of 19mm (also need the backing plate or a round file)

the non-abs models, which are the ones that have a rear load sensitive bias valve have a different axle beam. there is an extra small lever for the bias valve, also the rear brake pipes are different too

Thank you.....
