Hi mate. I would not re pipe it. It needs to be a front rear split circuit.

U need the bias valve to get the balance right. I would say it is air in the caliper. I have seen it before - i think u need to alter the height of the car or something when bleeding.

By all means check the piping over, but assuming its a front rear split, then the piping isn't the problem.

is he bleeding the rears with the wheels on the ground?

if not thats your problem

and are the bleed nipples on the wilwoods at the top ie has he got them on the right sides?

just now its basically both front calipers are piped together to the same conection on master cylinder and rears are plumbed together through the bias valve from another connection on the master cylinder. does it matter which take off point on the servo goes to front or rear?????????

Rick

u mean master cylinder?

That is only the case with the std bias valves?

rick, true, i missed that lol

is the mater cylinder not a 3 output thing?

should have one line from M/S to each front

and 1 single split to the rears
