| -2- of the brakes. We cannot. I can spring the foot pedal easy two inches. On the road, can get up out of the seat and put all the weight I can on the foot pedal without an atom more braking. We had the servo down last night and noted that the back plate was doing little or no work, the shaft showed it to be too tight. We eased this. The anchor bearing is sloppy and once more demonstrates the wretched design of this piece. There is a strong tendency for the spring plates to stick. It is getting over lubricated, the front Ferodo disc was oiled up. To put it mildly we are disgusted with the servo. We note your remarks re. the omission of end movement for the ball bearing, our having eased the shaft may help us, but as we are taking the clutch down, we will make sure of this point. RE. SHOCK DAMPERS. You do not say in your memo. whether the gland has been strengthened up. In our opinion this is the cause of the trouble, and until this is made right, no kind of packing will be oil tight. RE. SPEED AND ROADS. We can assure you that the car is being driven fast enough. If you will glance at the average yesterday, it will assure you, and as for bad roads, at the present moment we have a job to see anything underneath the car, it is solid with sludge. Our previous moderate average speeds was, as I have stated, due to head winds and hilly district, although driving really hard. RE. LOSS OF OIL FROM ENGINE. I carried out another test yesterday without the help of the wind catcher on the clutch cover. We collected for the 500 miles just over an 1/8 of a pint. With the wind catcher in position, or in other words creating a positive pressure in the clutch casing, we collected none. We are again proving it out today. DAMPER ANCHORAGE. Since putting an extra 3/8" packing under the rear buffers, our dampers have remained firm. Previously we could not keep the bolt in the aluminium bracket tight. | ||
