It may be interesting to compare the specs of the dual servo to the specs of the standard Sierra servo, if the dual is giving more boost, maybe a bias would be needed when running disc all round. I gues it would be less of a problem with a drum backend. I guess the only true way to test it would be to run a car with the modified brake setup on a rolling road brake tester as used for IVA.

This ties in with a question from MBM - they were asking if we needed a brake bias valve to go with the servos?
Sounds like we may do?
Better ask Jason to go and do some more brake tests!
Stand on the brakes
Hang head out the side
Look forward - is wheel skidding?
Look rearwards - is wheel skidding?
Report back on whether break bias valve is required!
