Hey guys

quick background car ae86, im running a zenki jdm disc rear end. up front there is some magna rotors and holden single pot calipers. running a nissan r32 master. I have also gutted the preportion valve as the rears were not doing enough work. im pretty happy with the brakes she stops well BUT under really hard braking the front locks up.

now i have been scoping flea bay and there is some wilwood brake bias valves. to me these just look like a restrictor and normally fitted to the rear brake lines.

my problem is the fronts are doing to much work can i fit one of these valves on the front brakes? to try and let the rears do some more work?

any light on the subject would be great
cheers
