Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}4/KW.14.5.36. Phantom III Front Brakes Binding on full rebound. With regard to the trouble that front wheels cannot be rotated when the car is jacked up to its full extent with hydraulic jacks, we were requested by Da.{Bernard Day - Chassis Design} to find out whether altering the limiting position of the brake dashpot should overcome this trouble. We find that by arranging the piston in the "off" position to be 3/16" further from the end of the cylinder, the brakes free themselves. We have run 36-EX on the road under this condition and there is no "clank" when the brakes come off. We recommend therefore that cars leave the Works with the required rod lengthened 3/16". This necessitates decreasing the length of the front brake rope an amount which must be calculated from the leverage of the idler lever in question.
