It has only become a chronic complaint with the 7 to 1 reduction. This, we consider, is the worst point to overcome in the adopted scheme of brakes. As regards the pedal pressure required to operate the brakes. 35-PK which was sent to WW. was on the light side - some other cars have required definitely more pressure. We consider 35-PK is as light a pedal pressure as desirable. We are hoping the average will require more pressure. We have arranged with the Works not to get too g- far ahead on the levers fitted with the cams so that we can increase the pressure required if experience decides this is desirable.
