I have fitted a Willwood style brake bias knob that projects above the top of the transmission tunnel about 6 inches from the front bulkhead (ie; under the dash area) I have set the bias (correctly for SVA I hope!!!) and now need to lock the knob in that position for SVA. Has anyone a method of doing this that can, er, fail shortly after. I intend to cover the knob with a foam sleeve for the test.

These have been completely banned for IVA, so I would guess for SVA they will be looking for it to be very 'tamper proof' (particularly when it's cockpit adjustable).

Remove it the --- even at minimum setting the Willwood valve only really operates at hydraulic pressures well above those you would expect to see in a Seven style car.

If you have overszed rear brakes feel you need a valve fit either an Uno or Ritmo/Strada/Lada valve or the valve from a FWD Ford that screws into the master cyilnder outlet.
