try the brake proportioning valve is working and correctly adjusted.
cheers brett

i adjusted the bias valve by grinding out the holes to set the spring to a length of 207 mm as per the w/shop manual dont have any gauuges to test the brake pressures though.

does any one know about the rear brake bias valve? the front pads are worn out and the rear ones are like brand new, over brakes on the front (locks front too easily).
